Resumen

A diverse radiolarian fauna is described from strata of a road cut section of the uppermost part of the Bell Canyon Formation (Capitanian, Guadalupian, Middle Permian), Apache Mountains, West Texas. Fifteen new species are described: Campanulithus insuetus, Pseudoalbaillella apachensis, Astroentactinia capitanensis, Polyedroentactinia guadalupensis, Afanasievella apachensis, Copicyntra erinacea, Paracopicyntra snyderi, Klaengspongus planus, Copiellintra orbiculata, C. fastuosa, Shangella capitanensis, Rectotormentum wardlawi, Tetratormentum ormistoni, Quadrilobata? blomei, and Nazarovispongus globosum. The diagnoses of the species Follicucullus sphaericus Takemura in Takemura et al. 1999 and the genus Raciditor Sugiyama 2000 are emended. The rank of the subspecies Raphidociclicus gemellus americanus Nazarov and Ormiston 1985a is raised to species level. The genus Nazarovispongus Kozur 1980 is considered to be a valid genus and is reinstated. Established are one new genus, Afanasievella (assigned to the family Spongentactiniidae), one new subfamily Polyedroentactiniinae (in the composition of the family Orosphaeridae), and one new family Tetratormentidae (in the composition of the order Pyramidata). The radiolarian assemblage from the described section in the Apache Mountains is at least partly coeval with the radiolarian assemblage from the Reef Trail Member of the Bell Canyon Formation in the Guadalupe Mountains, allowing a straight correlation of this age strata between the Apache and Guadalupe mountains. This correlation is supported by the conodont species that define the latest Guadalupian conodont zones and that occur together with radiolarians in both areas. The radiolarian species Albaillella yamakitai in sense of Xia et al. (2005) present in the late Guadalupian J. altudaensis conodont Zone cannot be a marker for the Guadalupian – Lopingian boundary as was proposed by Xia et al. (2005).

Resumen

The conodont species Caenodontus serrulatus Behnken is a rare coniform element first described in 1975 from Guadalupian strata exposed in the Guadalupe and Delaware Mountains of West Texas. Because it is rare, coniform, and occurs long after most coniform elements supposedly disappeared, it has been hauntingly mysterious. Based on new material containing a varied assemblage of coniform elements recovered from an outcrop of the Hegler Limestone (Guadalupian) in the Patterson Hills, West Texas, it is proposed that Caenodontus is comprised of a 6-7 membrate coniform apparatus and that this apparatus is very similar to the one proposed for the genus Ansella from the Ordovician.

Resumen

Millions of devotees acclaim the Nahuatl-language Nican mopohua account of the apparitions of Our Lady of Guadalupe to Juan Diego as the foundational text of the Guadalupe tradition. A number of scholarly analyses have also examined the Nican mopohua as a prime source for that tradition. But no previous study has focused on a theological examination of Luis Laso de la Vega's Huei tlamahuiçoltica (1649), in which the Nican mopohua was first published. Huei tlamahuiçoltica is the premier Guadalupan pastoral manual and encompasses other important material, such as the Nican motecpana account of miracles attributed to Guadalupe's intercession, and the earliest published synopsis of Juan Diego's life posed as a model for Christian discipleship. This article explores Laso de la Vega's contributions and the ongoing significance of his treatise for the development of theological works and pastoral ministries centered on Guadalupe.

Resumen

Moderately well-preserved radiolarians are described from two measured sections of the Reef Trail Member of the Bell Canyon Formation (Middle Permian), exposed in the Patterson Hills, Guadalupe Mountains National Park, West Texas. The Reef Trail Member is the youngest member of a series of basinal marine carbonates deposited in the Delaware basin prior to the deposition of the Castile Formation evaporites, and represents the uppermost Guadalupian (upper Capitanian). The Guadalupian-Lopingian boundary is presumed to occur at or just above the top of the Reef Trail-Castile contact because of the presence of C. postbitteri hongshuiensis ~ 2m below the top of the Reef Trail Member in sections in the Patterson Hills. A total of 30 genera containing 51 species were recovered from the Reef Trail Member, belonging to the orders Albaillellaria, Latentifistularia, Spumellaria, and Entactinaria. The following new taxa are described: Raphidociclicus scutum, Camptoalatus volaticus, Pseudoalbaillella delawarensis, Astroentactinia porosa, Stigmosphaerostylus favusa, Polyedroentactinia quadrata, Praedeflandrella firmata, P. prolata, Copicyntra spinosa, Copicyntra irregulata, and Paracopicyntra puncta, and Copicyntroides nazarovi. The following taxa are emended: Raciditor scalae (Caridroit and De Wever 1986), and Klaengspongus Sashida 2000b. Near the top of the Reef Trail Member, there are marked fluctuations in the relative abundances of albaillellarian and latentifistularian species. Fluctuations are possibly controlled by paleoenvironmental changes associated with the onset of the end-Guadalupian extinction event. Biostratigraphically, the fauna most closely correlates with the widely recognized F. bipartitus – F. charveti Zone sensu Caridroit, which we now consider to be uppermost Guadalupian, not Lopingian, and to the Guadalupian F. charveti Zone of Sun and Xia 2006 from oceanic facies in China. Both older and younger biostratigraphic markers also occur in the Reef Trail fauna, including Pseudoalbaillella longtanensis and A. yamakitai, requiring a reevaluation of the reliability of these albaillellarian taxa in biostratigraphy.

Resumen

Despite being recognized for many years, bentonites in the Guadalupian (Middle Permian Series) type area of West Texas and southeastern New Mexico have received little research attention. These important deposits offer opportunities for long distance stratigraphic correlation and high-precision radioisotopic age dating. In this study, apatite phenocryst chemistry is used to establish a tephrochronologic framework for the Manzanita Limestone Member of the Cherry Canyon Formation. Samples were collected from bentonites in one core and five field localities including Nipple Hill, which is the site of the Late Guadalupian (Capitanian Stage) GSSP and located in Guadalupe Mountains National Park. Apatite phenocrysts from these samples were analyzed for minor, trace, and rare earth element chemistry using electron microprobe techniques. Results indicate the presence of three patterns or trends of data that are repeated at multiple localities. These groups of data are interpreted to represent coeval deposits and are correlated among several localities to form a tephrochronologic framework. This framework links the strata on Nipple Hill with that of several other Guadalupian type area localities. Absolute age time control for the Guadalupian is poor, and the precise stratigraphic position of the existing radioisotopic date from Nipple Hill is uncertain. Based on a review of published reports and a new measured section of Nipple Hill presented herein, the most accurate position is in the Manzanita Member. That placement adjusts the only radioisotopic age constraint for the Capitanian GSSP lower in the Wordian Stage than previously reported. The bentonite correlations proposed herein constrain this position to the Mz-3 cycle of the Manzanita High Frequency Sequence and allow it to be traced to several outcrop localities, and across the Delaware Basin in the subsurface. Based on the correlation of a bentonite from its locus typicus near Caseyâ€™s Last Chance Well in Culberson County, Texas, the type specimen of the biostratigraphically significant ammonoid Newellites richardsoni is confirmed to have been recovered from the basal Manzanita Member (Wordian Stage), stratigraphically underlying the radioisotopic age date. The type locality of this ammonoid has been inconsistently reported in museum records and in the literature.

Resumen

A small faunule of silicified hexactinellid sponges and root tufts has been recovered from the upper Guadalupian Reef Trail Member of the Bell Canyon Formation, from the Patterson Hills, in the southwestern part of the Guadalupe Mountains National Park in western Texas. Some demosponges from the type section of the Reef Trail Member, near the mouth of McKittrick Canyon on the front of the Guadalupe Mountains in the park, have also been documented. Included in the faunule from the Patterson Hills localities are the new amphidiscosid hexactinellid pelicasponge Trailospongia reischi n. gen. and sp., the questionable pelicaspongiid Hexirregularia nana n. gen. and sp., and the dictyospongiid hexactinellids Microstaura doliolum Finks, 1960, and Microstaurella minima n. gen. and sp., and Microstaurella parva n. gen. and sp. They are associated with specimens of the lyssacinosid brachiosponges Toomeyospongiella gigantia Rigby and Bell, 2005, Toomeyospongia modica n. sp., and Toomeyospongia minuta n. gen. and sp., and fragments of three different types of root tufts, termed Tufts 1, 3, and 4. Two specimens of the new cylindrical demosponge Mckittrickella pratti n. gen. and sp. are associated with Tuft 2 in the collection from the type section of the Reef Trail Member, and a third specimen was collected from the member in the Patterson Hills. These sponges from Localities 1-7 are the youngest Permian sponges known from the region, and possibly from North America.

Resumen

Spongy radiolarians are described from strata of the Roadian Stage (Guadalupian, middle Permian) exposed in a small quarry (Quarry section) in the Guadalupe Mountains,West Texas. These radiolarians are assigned to the orders Entactinaria (conditionally) and Spumellaria. Two new families Hegleriidae and Glomispinidae are proposed. The genus Hegleria Nazarov and Ormiston and its two species, H. mammilla (Sheng andWang) and H. mammifera Nazarov and Ormiston are discussed. Based on an analysis of the distribution and preservation of the illustrated specimens of these two species in the literature, it is proposed that the species H. mammilla should be considered as nomen dubium. The genus Uberinterna Sashida and Tonishi and one species Copicyntra simulens Nazarov and Ormiston are revised. Five new genera, Texasospongites, Allenispongus, Cutoffella, Glomispina, and Orminazarella, and ten new species Texasospongites fazleevi, Allenispongus nobilis, Cutoffella perplexa, Glomispina mirifica, Uberinterna hearstae, U. ancestralis, Provisocyntra vancouveringi, Orminazarella nuda, Paracopicyntra bella, and Copiellintra variabilis are described.

Resumen

Roadian radiolarians are described from strata exposed in a small quarry (Quarry section) on U.S. Highway 62/180 located 3 km northeast of its junction with Texas Highway 54, Culberson County, Guadalupe Mountains, West Texas. These strata were long considered as Bone Spring Limestone of Leonardian (Early Permian) in age, but in recent years have been assigned to the Williams Ranch Member of the Cutoff Formation of the Roadian Stage (Guadalupian, middle Permian) based on the presence of the ammonoid species Paraceltites elegans. Radiolarians are of excellent preservation and the fauna is very diverse with 29 species of 11 genera described belonging to orders Albaillellaria and Entactinaria.Among them, 15 new species and one new genus, Apachevella, have been described, and five species emended. New species are Campanulithus cutoffi, Albaillella exilis, Pseudoalbaillella pseudoscalprata, P. japonica, P. laevis, Entactinia siciformis, E. longiacus, E. rezedae, Trilonche belli, Entactinosphaera texana, Polyedroentactinia macilenta, P. cancellata, P. porosa, P. bifida, and Kashiwara roadensis. Emended species are Pseudoalbaillella cona Cornell and Simpson, Entactinia parapycnoclada Nazarov and Ormiston, Trilonche tyrrelli (Nazarov and Ormiston), Apachevella capitanensis (Nestell and Nestell), and Wuyia endocarpa (Nazarov and Ormiston). Conodonts are represented by Jinogondolella nankingensis (Jin) with its three subspecies, J. nankingensis nankingensis (Jin), J. nankingensis behnkeni Wardlaw and Nestell and J. nankingensis tenuis Wardlaw, and elements of Sweetina and Hindeodus wordensis Wardlaw.

Resumen

Middle Permian (Guadalupian) ostracods are described from the Williams Ranch Member of the Cutoff Formation (Roadian) and the McKittrick Canyon Member of the Bell Canyon Formation (Capitanian) from two sections exposed in Culberson County, Guadalupe Mountains, West Texas. Their taxonomy is discussed and adds to the scientific understanding of marine ostracod biodiversity and palaeobiogeography during the Middle Permian. Ostracod assemblages are represented by 51 species of 26 genera and 15 families. Eleven species are newly described: Healdia mckittrickensis Crasquin sp. nov., Healdia cutoffella Crasquin sp. nov., Aurikirkbya guadalupensis Crasquin sp. nov., Hollinella (Hollinella) williamsranchensis Crasquin sp. nov., Geisina culbersonensis Crasquin sp. nov., Paraparchites pecosensis Crasquin sp. nov., Bairdia elcapitanensis Forel sp. nov., Ceratobairdia mescaleroella Forel sp. nov., Ceratobairdia sexagintaduella Forel sp. nov., Ceratobairdia pratti Forel sp. nov., and Denticupachydomella bellcanyonensis Forel sp. nov. The diagnosis of the genus Denticupachydomella is emended. The palaeobiogeographic distribution of the species is analyzed and exemplifies the taxon exchanges between Tethyan and Panthalassic localities in the Permian. The eastern margin of the Palaeo-Tethyan realm is shown to have played a major role in radiation of taxa in the Permian.

Resumen

Spatial and temporal variations in biological diversity are critical in understanding the role of biogeographical regulation (if any) on mass extinctions. An analysis based on a latest database of the stratigraphic ranges of 89 Permian brachiopod families, 422 genera, and 2059 species within the Boreal, Paleoequatorial, and Gondwanan Realms in the Asian–western Pacific region suggests two discrete mass extinctions, each possibly with different causes. Using species/family rarefaction analysis, we constructed diversity curves for late Artinskian–Kungurian, Roadian–Wordian, Capitanian, and Wuchiapingian intervals for filtering out uneven sampling intensities. The end-Changhsingian (latest Permian) extinction eliminated 87–90% of genera and 94–96% of species of Brachiopoda. The timing of the end-Changhsingian extinction of brachiopods in the carbonate settings of South China and southern Tibet indicates that brachiopods suffered a rapid extinction within a short interval just below the Permian/Triassic boundary.In comparison, the end-Guadalupian/late Guadalupian extinction is less profound and varies temporally in different realms. Brachiopods in the western Pacific sector of the Boreal Realm nearly disappeared by the end-Guadalupian but experienced a relatively long-term press extinction spanning the entire Guadalupian in the Gondwanan Realm. The end-Guadalupian brachiopod diversity fall is not well reflected at the timescale used here in the Paleoequatorial Realm because the life-depleted early Wuchiapingian was overlapped by a rapid radiation phase in the late Wuchiapingian. The Guadalupian fall appears to be related to the dramatic reduction of habitat area for the brachiopods, which itself is associated with the withdrawal of seawater from continental Pangea and the closure of the Sino-Mongolian seaway by the end-Guadalupian.

Resumen

Several specimens of the large, discoidal, new inozoid genus and species, Gigantospongia discoforma, have been discovered in the Upper Permian, Upper Capitan Limestone in the northern Guadalupe Mountains of New Mexico, near Carlsbad Caverns. The holotype is nearly 2.5 meters across, as exposed, and ranges from 8-20 mm thick, with numerous canals transverse and parallel to the principal plane. These canals are approximately 1 mm in diameter and separated by tracts 1-2 mm thick. Thickened dermal and gastral layers, each approximately 1 mm thick, occur at tops and bases of both the holotype and associated paratypes in the “Sponge Window” exposures of Bat Cave Draw, and in specimens from Chinaberry and Hackberry Draws. Inverted Lemonea conica Senowbari-Daryan, 1990, is apparently attached to the base, and appears to have grown inverted in a void formed or capped by the tabular inozoid. Well-preserved specimens of Amblysiphonella also appear inverted, as do examples of Lemonea cylindrica (Girty, 1908), a new species of Lemonea, and Guadalupia explanata (King, 1943), which occur between the holotype and an underlying paratype. All appear coated with Archaeolithoporella crusts. Microstructure of the inozoan skeleton is obscured by diagenesis.

Resumen

AbstractThe discovery and dating of a volcanic ash bed within the upper Phosphoria Formation in SE Idaho, USA, is reported. The ash occurs 11 m below the top of the phosphatic Meade Peak Member and yielded a 206Pb/238U date of 260.57 ± 0.07 / 0.14 / 0.31 Ma, i.e. latest Capitanian, Guadalupian. The stratigraphic position of this ash near the top of the Meade Peak phosphatic Member of Phosphoria Formation indicates plausible completeness of the sedimentation within the Guadalupian–Lopingian and probably at the Permo-Triassic (P-T) transitions. The new radiometric age reveals that the regional biostratigraphy and palaeontology of Phosphoria and Park City formations requires serious reconsideration, particularly in cool water conodonts, bryozoans and brachiopods. The new age proposes that the Guadalupian–Lopingian boundary (GLB) coincides with the Meade Peak – Rex contact and consequently with the end-Guadalupian extinction event. The lack of a major unconformity at the P-T transition suggests that the effects of the Sonoma orogeny were not as extensive as has been assumed.

Resumen

The Permian reef complexes of West Texas and New Mexico are among the classic carbonate sequences in the world and have significantly influenced geologic thinking for over half a century. Study of the reefs can be subdivided into 6 broad periods. The first period involved early exploration of the region, establishment of regional stratigraphic relationships and attempts at dating stratigraphic units. The Guadalupian Fauna typifies this early period. The second period, during the 1920-30's, was a time of early petroleum exploration in the region, following on discovery of the Kendrick Field in Winkler County, Texas, and resulted in attempts to explain the complicated subsurface stratigraphy. Development of a marginal reef model and research on facies relationships between the basin and shelf resulted in refinement of stratigraphic nomenclature.The third period, here termed the King period, was a time of more intense study of the outcrops and their subsurface extensions. It was a time when facies became more clearly differentiated and when the great diversity and abundance of fossils in the region became appreciated. This period ended when World War II curtailed research in the region. The fourth period began after the war, with heightened interest in reefs and paleoecology. It was a time when carbonate petrology and paleoecology rose as major fields of interest. It was also a time of mega-paleontology. Tens of tons of fossiliferous limestones were processed at the U.S. National Museum and the American Museum of Natural History and collections of literally millions of fossils were assembled. The earlier publication of Geology of the Southern Guadalupe Mountains, Texas and the later publication of The Permian Reef Complex of the Guadalupe Mountains Region, Texas and New Mexico characterize the period.The fifth period is marked by the return of industry investigators to study the reefs and associated rocks, perhaps spurred as much by Dunham's "Vadose pisolites in the Capitan reef" as by any single paper. The period was one of concern about origins of the distinctive pisolites of the complex, nature of the massive Capitan Limestone, diagenesis of carbonates and by concern for understanding the economically significant rocks of the backreef sequence. The sixth period, termed the Wisconsin phase, continued research along lines of the fifth period but was a time when faculty and students of the University of Wisconsin, and their associates, re-examined all facies of the Guadalupe Mountain reef complexes as a major effort, while industry became less broadly involved. Those efforts, and those now initiated by faculty and students of the University of Nebraska and Rice University, bring us essentially to date, but much still remains to be discovered and understood about the reef complexes.

Resumen

AbstractThe Guadalupian (middle Permian) extinction may have triggered substantial ecological restructuring in level-bottom communities, such as turnover in dominant brachiopod genera or a shift from abundant brachiopods to mollusks, despite comparatively minor taxonomic losses. However, ecological changes in relative abundance have been inferred from limited data; as a result, constraints on important shifts like the brachiopod-mollusk transition are imprecise. Here, I reevaluate the magnitude of ecological shifts during the Guadalupian–Lopingian (G-L) interval by supplementing previous census counts of silicified assemblages with counts from non-silicified assemblages and global occurrence data, both sourced from the Paleobiology Database. Brachiopod occurrences are consistent with more pronounced faunal composition changes from the Guadalupian to Lopingian than among stages within those intervals, but only in Iran and South China, and not in Pakistan or a Tethys-wide data set. In Iran and South China, Bray-Curtis dissimilarity values comparing occurrence frequencies between adjacent stages were elevated across the G-L transition, although other intervals exhibited similarly large shifts. However, genus occurrence frequencies were less strongly correlated or were anti-correlated across the G-L transition, suggesting moderate faunal turnover among dominant brachiopod genera. In contrast to previous inferences from silicified faunas, abundances of brachiopods, bivalves, and gastropods remained consistent from the Guadalupian to Lopingian in non-silicified local counts and global occurrences, implying that the brachiopod-mollusk shift did not occur until the end-Permian extinction. Ecological and taxonomic consequences were both minor in level-bottom settings, suggesting that severe environmental perturbations may not be necessary to explain biotic changes during the Guadalupian-Lopingian transition.

Resumen

Percina sciera apristis (Hubbs & Hubbs) was described as a subspecies based on the hypothesis that the population in the Guadalupe River system was morphologically distinct from other populations and that populations geographically closest to the Guadalupe River were intergrades between P. s. sciera and P. s. apristis. Our data confirm the decision to recognize the population in the Guadalupe River as taxonomically distinct; however, western Gulf populations closest to the Guadalupe River do not show a consistent pattern of intermediacy in meristic variables. The Guadalupe population has extreme numbers of preopercular serrae, pored lateral-line scales, modified scales, caudal-peduncle scales, and anal rays. The most extreme trait is the number of preopercular serrae; 95% of individuals from the Guadalupe, but only 6% from other western Gulf drainages, have 0–3 serrae. Sixty-eight percent of Guadalupe individuals, but only 4% from elsewhere, have no serrae. These extreme values demonstrate that the Guadalupe population is genetically isolated and diagnosable as Percina apristis (Hubbs & Hubbs), the Guadalupe Darter.

Resumen

A mid-Permian (Guadalupian epoch) extinction event at approximately 260 Ma has been mooted for two decades. This is based primarily on invertebrate biostratigraphy of Guadalupian–Lopingian marine carbonate platforms in southern China, which are temporally constrained by correlation to the associated Emeishan Large Igneous Province (LIP). Despite attempts to identify a similar biodiversity crisis in the terrestrial realm, the low resolution of mid-Permian tetrapod biostratigraphy and a lack of robust geochronological constraints have until now hampered both the correlation and quantification of terrestrial extinctions. Here we present an extensive compilation of tetrapod-stratigraphic data analysed by the constrained optimization (CONOP) algorithm that reveals a significant extinction event among tetrapods within the lower Beaufort Group of the Karoo Basin, South Africa, in the latest Capitanian. Our fossil dataset reveals a 74–80% loss of generic richness between the upper Tapinocephalus Assemblage Zone (AZ) and the mid- Pristerognathus AZ that is temporally constrained by a U–Pb zircon date (CA-TIMS method) of 260.259 ± 0.081 Ma from a tuff near the top of the Tapinocephalus AZ. This strengthens the biochronology of the Permian Beaufort Group and supports the existence of a mid-Permian mass extinction event on land near the end of the Guadalupian. Our results permit a temporal association between the extinction of dinocephalian therapsids and the LIP volcanism at Emeishan, as well as the marine end-Guadalupian extinctions.

Resumen

The uppermost 5–15 m of the Douling Formation in the southern Hunan area, South China, yields a diverse fauna comprised of ammonoids, bivalves, and brachiopods. The brachiopods reported in this paper consist of 51 species in 34 genera and are dominated by the Lopingian (Late Permian) species associated with a few species persisting from the underlying Maokouan (Late Guadalupian). This fauna is of earliest Wuchiapingian in age as precisely constrained by the associated conodontClarkina postbitteri postbitteriand the Guadalupian-type ammonoid fauna of theRoadoceras-DoulingocerasZone in the brachiopod horizon. The discovery of the Lopingian species-dominated brachiopod fauna in the earliest Wuchiapingian in southern Hunan suggests a much less pronounced effect of the pre-Lopingian crisis (end-Guadalupian mass extinction) than the end-Changhsingian mass extinction in terms of brachiopods, a contemporaneous onset of the Lopingian recovery/radiation during the pre-Lopingian crisis period, and taxonomic selectivity of the pre-Lopingian crisis in terms of different fossil groups. New taxa areEchinauris doulingensisn. sp.,Pararigbyella quadrilobatan. gen. and n. sp. andP. doulingensisn. gen. and n. sp.

Resumen

A fusuline fauna consisting of 9 species of 4 genera from the Xiala Formation of the Mujiucuo section, Xainza County, Tibet, China is described. The fusuline fauna is dominated byNankinellaandChusenellaand indicates a Midian (Late Guadalupian) age. The earliest record of fusuline fauna during the Midian in the Lhasa Block suggests that the block rifted later than the Qiangtang Block to the north and the Baoshan and Tengchong blocks to the east, all of which yield much earlier fusuline faunas of Yakhtashian (Artinskian) age, but had drifted away from Gondwana to a relatively warm temperate zone in the Late Guadalupian (Middle Permian).

Resumen

The base of the Guadalupe Group, in the Tunja area of Colombia, contains cherts, porcellanites, mudstones, and siltstones with subordinate quartz arenites. The lithostratigraphic description of two stratigraphic sections showed that the dominant facies have fine granular textures and siliceous compositions, which considerably differ from those of the prevailing sandy terrigenous facies described in the type locality in the Eastern Hills of Bogotá, in the Arenisca Dura Formation, the basal unit of the Guadalupe Group in this sector. The units that form the Guadalupe Group (base of the Guadalupe Group, Plaeners, and Arenisca Tierna) markedly differ from each other morphologically, which facilitates their mapping because the base and top units generate a steep morphology, and the intermediate units form surface depressions or valleys, similar to the morphology of the Guadalupe Group in its type locality in the Eastern Hills of Bogotá. The base of the Guadalupe Group consists of cherts and porcellanites toward the NW of the study area (Alto del Gavilán section), with mudstones, siltstones, quartz arenites, and to a lesser extent porcellanites and cherts prevailing toward the SE (Vereda Salitre section). Geochemical analysis of total rock samples by XRD and XRF confirmed the primarily siliceous nature of the base of the Guadalupe Group, with SiO2 ranging from 62 to 98%, CaO less than 3.0%, and P2O5 peaking at 15.0%. Etayo-Serna (2015) conducted paleontological determinations of ammonites found in the stratigraphic section of Alto del Gavilán and assigned the base of the Guadalupe Group mainly to the Lower Campanian.

Resumen

A global database of middle–upper Permian foraminiferal genera has been compiled from the literature for 75 Guadalupian and 62 Lopingian localities, grouped into 32 and 19 operational geographical units respectively. Cluster analysis reveals that five distinct Guadalupian provinces were reduced to four in the Lopingian, following the disappearance of the Eastern Panthalassa Province. Extinction magnitudes across the Guadalupian/Lopingian (G/L) boundary reveal that, in the remaining provinces, there is a strong regional variation to the losses at low paleolatitudes. The Central and Western Tethys Province experienced a markedly lower extinction magnitude, at both provincial and global levels, than the Eastern and Northern Tethys Province. Panthalassa experienced a high extinction magnitude of endemics, but a global extinction magnitude similar to that recorded in Central and Western Tethys. This regional bias is seen in both the fusulinacean and non-fusulinacean foraminifera, although fusulinaceans suffered much higher magnitudes of extinction. The regional selectivity also persisted during the subsequent Lopingian radiations, with the Central and Western Tethys Province recording the greatest magnitudes. Thus, of 35 new genera recorded globally from the Lopingian, 27 of these are recorded in Central and Western Tethys, compared to five and 12 genera respectively in Panthalassa and in Eastern and Northern Tethys. The Emeishan large igneous province erupted within the Eastern and Northern Tethys Province and may have been a factor in the high extinction–low radiation regime of this region. Regression (and consequent shallow-marine habitat loss) also appears to have been a significant factor. A major, but brief, late Guadalupian regression is best seen in those areas that suffered the greatest extinction losses.

Resumen

The Karakaya Complex in northern Turkey is classically subdivided into two units (Upper and Lower Karakaya Complex) and located in the Sakarya Composite Terrane. The Upper Karakaya Complex includes different blocks and tectonic slices within a Triassic matrix. A new genus of miliolid foraminifera (Cornuspiroidea, Neodiscidae) is established from the late Capitanian (latest Guadalupian) neritic limestone block from the Upper Karakaya Complex. The new genus Globidiscus is characterized by a large, inflated lenticular in the axial and subglobular in transverse section and involute test with well-developed flosculinisation and a porcelaneous wall with buttresses. It was probably derived from the Praeneodiscus-Neodiscus lineage in late Capitanian (Guadalupian).

Resumen

After having been observed regularly at Seal Cove, San Clemente Island, California, since 1994, the Guadalupe Murrelet (Synthliboramphus hypoleucus) was confirmed nesting successfully in an artificial nest on a rocky ledge above the cove in 2022. The incubating adults’ identity and the two chicks’ departure from the nest were confirmed by a trail camera. Another Guadalupe Murrelet nest at Santa Barbara Island in 2021 was only the second confirmed there. Though the populations of the Guadalupe Murrelet at San Clemente and Santa Barbara islands are apparently small, they are important in representing the only confirmed sites of the species’ nesting away from Guadalupe and the San Benito islands.

Resumen

ABSTRACT Thirty-three brachiopod species from the Guadalupian Ruteh Limestone of North Iran are here systematically described and illustrated. Brachiopods have been collected bed-by-bed along five stratigraphic sections and in one fossiliferous locality in the region between Dorud and Shirinibad in the Alborz Mountains. Four new species and one new genus are erected in the present paper: Haydenella eminens n. sp. Perigeyerella rutehiana n. sp., Martinia bassa n. sp. and Bisolcatelasma iraniana n. gen. n. sp. Quantitative biostratigraphic analysis of the brachiopod data based on the Unitary Association method (Guex, 1991) has lead to the construction of a local sequence of three discrete biozones: the Squamularia sp. B-M. bassa Biozone at the base of the formation, the H. kiangsiensis-N. (N.) asseretoi Biozone in its middle part and the R. exile-R. gemmellaroi Biozone at its top. The latter however has been recognized only in the Shirinabad section. As already envisaged for the Carboniferous and Lower Permian brachiopod faunas from North Iran, the Guadalupian fauna is comprised mostly of cosmopolitan taxa, confirming the role of the Iranian microplate as a staging-post for most of the late Palaeozoic. When compared to the younger Lopingian faunas collected in the same regions of North Iran, the Ruteh brachiopods appear significantly different, indicating a marked biotic change in the brachiopod communities across the end-Guadalupian biotic crisis.

Resumen

Pure marine chemical sediments are archives of geochemical proxies for the composition of seawater and may provide information about the ancient hydrosphere–atmosphere system. The early stage of the Emeishan large igneous province (ELIP) was characterized by the subaqueous eruption of mafic igneous rocks around the J. altudaensis zone of the Capitanian Stage that has been proposed to have contributed to the Guadalupian mass extinction. However, detailed mechanisms and the impact of the eruption on the Guadalupian marine environment have yet to be assessed. Here, to examine the Guadalupian marine environment, we studied major and trace element concentrations, particularly rare earth element and yttrium data, along with high-precision Sr-Nd isotope ratios, of three types of Mn ores (i.e., clastic, massive, and oolitic) and siliceous limestones from the Zunyi Mn deposit in South China formed following the early-stage eruption of the ELIP. Our results indicate that the clastic Mn ores contain notable detrital mafic aluminosilicates. In contrast, the massive and oolitic Mn ores and siliceous limestones preserved the pristine geochemical signatures of the Middle–Late Permian seawater characterized by distinctly low (87Sr/86Sr)i and high εNd(t) values. These data indicate a strong impact of the early-stage submarine eruptions of the ELIP on the marine environment in South China and worldwide, likely through intensive seawater–rock interaction.

Resumen

Devotion to the image of the Virgin of Guadalupe in Los Angeles has a complex and multifaceted history. This article will discuss the initial celebrations of Our Lady of Guadalupe, beginning with a procession in 1928 and developing with increasing popularity in the 1930s. By 1941, the Virgin of Guadalupe had become an important political and religious symbol for the archbishop of Los Angeles, John J. Cantwell, who conducted a pilgrimage to Mexico City, during which he reconfirmed the significance of the Guadalupe image for the Los Angeles Catholic community. In commemoration of Archbishop Cantwell's historic visit, a fragment of thetilma, the cloak on which the Virgin of Guadalupe representation had appeared, was offered to Los Angeles. As the only known piece of thetilmacurrently found outside of Mexico City, this relic has great devotional significance. As this article will show, thetilmarelic disappeared into relative obscurity following its arrival in Los Angeles, only to become a renewed focus of devotion over sixty years later, in 2003. This article will conclude with the reasons behind the relic's revival through a discussion of Juan Diego and his canonization.

Resumen

The end-Guadalupian extinction, at the end of the Middle Permian, is thought to have been one of the largest biotic crises in the Phanerozoic. Previous estimates suggest that the crisis eliminated 58% of marine invertebrate genera during the Capitanian stage and that its selectivity helped the Modern evolutionary fauna become more diverse than the Paleozoic fauna before the end-Permian mass extinction. However, a new sampling-standardized analysis of Permian diversity trends, based on 53731 marine invertebrate fossil occurrences from 9790 collections, indicates that the end-Guadalupian “extinction” was actually a prolonged but gradual decrease in diversity from the Wordian to the end of the Permian. There was no peak in extinction rates; reduced genus richness exhibited by all studied invertebrate groups and ecological guilds, and in different latitudinal belts, was instead driven by a sharp decrease in origination rates during the Capitanian and Wuchiapingian. The global diversity decrease was exacerbated by changes in beta diversity, most notably a reduction in provinciality due to the loss of marine habitat area and a pronounced decrease in geographic disparity over small distances. Disparity over moderate to large distances was unchanged, suggesting that small-scale beta diversity changes may have resulted from compression of bathymetric ranges and homogenization of onshore-offshore faunal gradients stemming from the spread of deep-water anoxia around the Guadalupian/Lopingian boundary. Although tropical invertebrate genera were no more likely than extratropical ones to become extinct, the marked reduction in origination rates during the Capitanian and Wuchiapingian is consistent with the effects of global cooling (the Kamura Event), but may also be consistent with other environmental stresses such as anoxia. However, a gradual reduction in diversity, rather than a sharp end-Guadalupian extinction, precludes the need to invoke drastic extinction mechanisms and indicates that taxonomic loss at the end of the Paleozoic was concentrated in the traditional end-Permian (end-Changhsingian) extinction, which eliminated 78% of all marine invertebrate genera.

Resumen

AbstractThe Guadalupian mass extinction took place during the major global environmental changes during Phanerozoic time. Large-scale sea-level fluctuations and a negative shift ofδ13C were associated with this crisis. However, the diagenetic or primary origin of the decreasedδ13C across the Guadalupian–Lopingian (G–L) boundary and the potential causes for this biotic crisis are still being intensely debated. Integrated analyses, including detailed petrographic examination, identification of foraminifer and fusulinid genera, and analysis of carbonateδ13Ccarband bulkδ13Corgacross the G–L boundary were therefore carried out at Tianfengping, Hubei Province, South China. Our results show that: (1) some foraminifer and most fusulinid genera disappear in the upper Maokou Formation (upper Guadalupian); (2) the negative shift ofδ13Ccarbin the uppermost Maokou Formation is of diagenetic origin, but the values ofδ13Ccarbin the remainder of the Maokou Formation and in the Wuchiaping Formation represent a primary signal of coeval seawater; and (3) the bulkδ13Corgperturbation across the G–L boundary at Tianfengping is mainly controlled by organic matter (OM) source, that is, terrestrial OM contribution. We suggest that theδ13Ccarbnegative shift in the lower Wuchiaping Formation (Wuchiapingian) compared to that in the lower–middle Maokou Formation (Capitanian) were probably caused by the re-oxidization of12C-rich OM during regression. Global regression resulted in the negative shift ofδ13Ccarbat the G–L boundary in South China and led to the loss of shallow-marine benthic habitat. Large-scale global regression is probably one of the main causes for this bio-crisis.

Resumen

El presente artículo consiste en un análisis de la transformación del mito guadalupano, a partir de tres textos producidos en momentos diferenciados de la historia de nuestro país: el primero escrito en el siglo XVI y publicado en el XVII; el segundo producido a finales del siglo XVIII, en los albores de la gestación del movimiento de Independencia y el último publicado en el siglo XIX, cuando México ya era un país independiente. Se trata en primera instancia del Nican Mopohua, —poema escrito en náhuatl y traducido al español por don Miguel León Portilla, quien con fundamentos documentales lo atribuye a Antonio Valeriano; en segunda instancia hablaré del Sermón guadalupano que, con motivo del día de la Virgen de Guadalupe del año 1794, pronunció fray Servando Teresa de Mier, ante el virrey y la clase política novohispana. Finalmente, analizaré la interpretación del mito que hace el narrador de la novela Los bandidos de Río Frío, de Manuel Payno.
