Abstract:

Two mosasaur tooth crowns collected from the Maastrichtian chalk sequences of Stevns Klint and Møns Klint are here assigned to Prognathodon, a mosasaur genus hitherto unknown from Denmark. Together with previous records of the mosasaurs Plioplatecarpus, Mosasaurus and Carinodens, these new finds of Prognathodon document the coexistence of four mosasaurid genera in the Danish chalk and underscore simi-larities to coeval assemblages from the Maastrichtian type area in the Netherlands and Belgium.

Abstract:

Abstract Although the presence of mosasaurids in the Late Cretaceous (Maastrichtian) Baculites limestone of the Cotentin peninsula, in the western part of Normandy (France), was reported as early as 1873 by Henri-Emile Sauvage, this occurrence has largely been overlooked by subsequent authors. In this paper we review Sauvage’s original material (an isolated tooth – the type of Mosasaurus platyodon) and describe an additional, hitherto unpublished, tooth crown also from the Baculites Limestone of the Cotentin and refer both to the globidensine mosasaur Prognathodon. Mosasaurus platyodonSauvage, 1873 is considered a nomen dubium.

Abstract:

AbstractUntil recently, mosasaur remains from the Izumi Group (Upper Cretaceous) in southwest Japan comprised only scattered finds; now a richer material is available. From the upper Campanian Hiketa Formation in Kagawa Prefecture, Kourisodon sp. has just been recorded, on the basis of portions of skull and mandible which has small and laterally compressed teeth. A few teeth of the same or similar type have previously been described from the Maastrichtian Mutsuo Formation in Osaka Prefecture. A report of Mosasaurus sp. A, which resembles M. missouriensis and M. dekayi, is based on some cranial and mandible remains, inclusive of numerous teeth and a few well-preserved cervical and two incomplete dorsal vertebrae, from the Maastrichtian Mutsuo Formation in Osaka Prefecture. A slender tooth of Mosasaurus sp. from the Mutsuo Formation has since been reassigned to Platecarpus (Plioplatecarpinae); yet, this may indeed by a species of Mosasaurus, here listed as Mosasaurus sp. B. To date, smaller specimens of mosasaurids have been shown to be abundant in the Izumi Group, which suggests two possible explanations. Either most of these represent juveniles, or smaller-sized, Kourisodon-like animals flourished here. Finds of Kourisodon sp. from the upper Campanian Hiketa Formation and the Maastrichtian Mutsuo Formation suggests the second explanation is the more likely one.

Abstract:

AbstractA global comparison of coeval Maastrichtian marine reptiles (squamates, plesiosaurs, chelonians and crocodyliformes) of Europe, New Jersey, northwestern Africa and Middle-East has been performed. More than twenty outcrops and fifty species (half of them being mosasaurids) have been recorded. PEA and Cluster Analysis have been performed using part of this database and have revealed that marine reptile faunas (especially the mosasaurid ones) from the Mediterranean Tethys are clearly segregated into two different palaeobiogeographical provinces: 1) The northern Tethys margin province (New Jersey and Europe), located around palaeolatitudes 30-40°N and developping into warm-temperate environments, is dominated by mosasaurid squamates and chelonioid chelonians; it is characterized by the mosasaurid association of Mosasaurus hoffmanni and Prognathodon sectorius. 2) The southern Tethys margin province (Brazil and the Arabo-African domain), located between palaeolatitudes 20°N-20°S and developping into intertropical environments, is dominated by mosasaurid squamates and bothremydid chelonians; it is characterized by the mosasaurid association of Globidens phosphaticus as well as by Halisaurus arambourgi and Platecarpus (?) ptychodon (Arabo-African domain). These faunal differences are interpreted as revealing palaeoecological preferences probably linked to differences in palaeolatitudinal gradients and/or to palaeocurrents.On a palaeoecological point on view and concerning mosasaurids, the mosasaurines (Prognathodon, Mosasaurus, Globidens and Carinodens) prevail on both margins but with different species. The ichthyophageous plioplatecarpines Plioplatecarpus (Northern margin) and Platecarpus (?) ptychodon (Southern margin) characterise respectively each margin. The halisaurine Halisaurus is present on both margins but with different species. Of importance, the tylosaurines remain currently unknown on the southern Tethys margin and are restricted to higher palaeolatitudes. Chelonians (bothremydids and chelonioids) are respective of each margin, which probably indicates lower dispersal capabilities compared to mosasaurids. The relative scarcity of plesiosaurs and crocodyliformes could be linked to different ecological preferences. The noteworthy crocodyliforme diversity increase in the Palaeogene is probably linked to mosasaurid extinction during the biological crisis of the K/Pg boundary.

Abstract:

Abstract Mosasaurs from Antarctica have been recovered from the late Campanian and early and late Maastrichtian in James Ross, Vega and Seymour Islands within the James Ross basin. Tylosaurinae are represented by the late Campanian-early Maastrichtian remains of Taniwhasaurus antarcticus [Novas et al., 2002] and by late Maastrichtian Tylosaurinae indet.; Plioplatecarpinae by late Maastrichtian Plioplatecarpus sp.; and Mosasaurinae by late Maastrichtian “Liodon” sp., Mosasaurus sp. and Mosasaurinae indet. Materials from Cape Lamb, recently identified in the Museo de La Plata collection (Argentina), suggest that the stratigraphic range of Plioplatecarpus and “Liodon” within the James Ross basin extends back to the early Maastrichtian. At present, the holotype of T. antarcticus is the most complete specimen exhumed from Antarctica. In northern Patagonia, mosasaurs have been recovered from the late Maastrichtian of the Jagüel Formation, Neuquén basin. Patagonian mosasaurs are represented by Mosasaurus sp. aff. M. hoffmanni, Plioplatecarpus sp., Prognathodon sp., and Mosasaurinae indet. Presently, no Tylosaurinae have been found in Patagonia. Both in the James Ross and Neuquén basins, Mosasaurus sp. and Plioplatecarpus sp. occurred close to the K/Pg. boundary.

Abstract:

This study provides a morphological description of the fragmentary skull of a mosasaur discovered in 1927 in the Upper Cretaceous (Maastrichtian) deposits in the city of Penza (Russia). Some bones from the original material had been lost since their discovery; their description is based on plaster casts. The Penza mosasaur displays characteristic features of Mosasaurus hoffmanni such as the posterior carina that shifts from a somewhat lateral position in the anterior teeth to a posterior position further along the tooth row, a frontal with convex lateral margins, and a powerfully built dentary. This is the first unequivocal record of this taxon from Russia. M. hoffmanni from the Penza is one of the largest mosasaurs ever known with an overall length of the body about 17 m.

Abstract:

AbstractKnowledge of habitat segregation of mosasaurs has been based on lithology and faunal assemblages associated with fossil remains of mosasaurs and stable isotopes (δ13C). These approaches have sometimes provided equivocal or insufficient information and, therefore, the preference of habitat by different mosasaur taxa is still suboptimally constrained. The present study is focused on the analysis of rare earth element (REE) ratios of mosasaur fossils from the Upper Cretaceous formations of western Alabama, USA. Results of the REE analysis are used to infer the relative paleobathymetry associated with the mosasaur specimens and then to determine if certain taxonomic groups showed a preference for a particular water depth. Comparisons are then made with mosasaur specimens reported in the literature from other regions of North America from different depositional environments. Results indicate that Mosasaurus, Platecarpus and Plioplatecarpus may have preferred more restricted habitats based on water depth whereas Tylosaurus and Clidastes favoured a wider range of environments. Results also suggest that Plioplatecarpus lived in a shallower environment than its Platecarpus predecessor. Although the results of this study are encouraging, caution must be exercised before drawing any final conclusions due to the small sample size of most of the taxa analysed.

Abstract:

Abstract New data regarding the placement of the Cretaceous-Paleogene (K/Pg) boundary in New Jersey is presented based on a recent campaign of drill coring boundary sections in the Atlantic coastal plain of southern New Jersey. The occurrence of late Maastrichtian mosasaurs worldwide and in New Jersey is reviewed in light of the continuing controversy over the rate and cause of the extinction at the K/Pg boundary. At the Meirs Farm site in Monmouth County, NJ, the biostratigraphic position of mosasaur specimens (Halisaurus platyspondylus, Mosasaurus hoffmann) is related to the occurrence of an iridium excursion of 0.5 ppb (5x background levels) in the basal Hornerstown Formation just above the upper Maastrichtian New Egypt Formation. Other specimens in museum collections obtained during the acme of nineteenth century marl mining are from this area of the Maastrichtian outcrop belt in New Jersey. It is concluded that late Maastrichtian mosasaurs show no diminution of their biogeographic ranges and are not particularly rare in New Jersey in comparison to older mosasaur faunas. Mosasaurs became extinct in association with the collapse of the marine food web at the K/Pg boundary, and were replaced as apical marine predators in the early Danian by a variety of crocodilians.

Abstract:

AbstractWe report here a large mosasaur skull, preserved three-dimensionally in a concretion recovered from Ziebach County, South Dakota, USA. This fossil represents the first articulated mosasaur skull from the Trail City Member of the Fox Hills Formation and the first definitive occurrence of Mosasaurus hoffmanni Mantell, 1829 from that area and the northernmost occurrence in the Western Interior Seaway, greatly extending the paleobiogeographic range of this taxon. The age of this specimen is determined to be between 68.3 and 67.6 Ma based on the associated invertebrate fauna. Although previous authors have suggested synonomy of the North American Mosasaurus maximus Cope, 1869 and the European M. hoffmanni, this is the most comprehensive analysis to date and is based on comparisons with Mosasaurus specimens recovered across the Northern Hemisphere, allowing an emended diagnosis of the species M. hoffmanni. Minor differences are considered individual variation or to reflect ontogenetic stage, including slender dentaries in some individuals, range of development of the C-shaped notch of the coronoid and differences in the shape of the supratemporal fenestra.

Abstract:

The transition between terrestrial varanoid lizards and aquatic mosasaurs through the intermediate, semi-aquatic aigialosaurs is fully documented. Aigialosaurs are shown to possess a mosaic of mosasaurian (configuration of the skull, jaw and tail) and terrestrial varanoid characters (appendicular skeleton and trunk).
The taxonomic position of the Aigialosauridae within the superfamily Varanoidea is evaluated. Based on character states previously used to define the Varanoidea, neither the specific affinities of aigialosaurs nor the sister-group relationships of earlier members of the terrestrial varanoid assemblage can be securely established. For this reason, the specific character states involved have been reexamined and alternative hypotheses of relationship have been considered.

Abstract:

South African mosasaur remains consist of a frontal with articulating portions of the parietal and postorbitofrontals (SAM-PK-5265); two dentary fragments (SAM-PK-5265) assigned to ‘Tylosaurus capensis' by Broom in 1912 (SAM-PK-5265); an undescribed muzzle unit and associated isolated teeth (CGP/1/2265) from Pondoland and a more recently discovered isolated partial vertebra from St Lucia. Some research has been done on the material, but there is still uncertainty concerning their relationships and taxonomy. This research aims to provide a taxonomic assessment of all the SA mosasaurid material to better understand their phylogenetic relationships and to place them in the context of mosasaurs from other parts of Africa and globally. In addition, isotopic analyses, micro-computed tomography (micro-CT), mineralised tissue histology and scanning electron microscopy (SEM) are applied to the SA mosasaur remains to decipher various aspects of their palaeobiology. This study identifies three mosasaur taxa from SA: Mosasaurus sp., cf. M. hoffmannii., cf. Taniwhasaurus, and cf. Prognathodon. The isolated vertebra is assigned to Mosasaurus sp., cf. M. hoffmannii. The frontal and dentary fragments (SAM-PK-5265) originally described as Tylosaurus appears to be a mix of two taxa: One of the dentary fragments possesses replacement teeth with enamel ornamentation that resembles, Ta. mikasaensis, but is tentatively assigned to cf. Taniwhasaurus based on tooth recurvature. The other dentary fragment and a frontal with articulated elements are suggested to belong to the same individual as the muzzle unit for which the suggested assignment is cf. Prognathodon. Strontium analysis of tooth enamel dated the cf. Prognathodon material to the end of the Maastrichtian (87Sr/86Sr = 0.707817; age = 66.85Ma). The cf. Taniwhasaurus dentary fragment is likely Santonian-aged, as originally indicated in 1901. SEM of enamel from cf. Prognathodon reveals a complex array of prismless enamel types and pervasive aggregations of fossilised bacteria in the underlying dentine. The δ18OPO4 derived body temperature estimate (Tb) of the cf. Prognathodon (Tb = 33.21°C) compares well with previously reported Tb for mosasaurs and may indicate that the mosasaur was capable of maintaining a Tb higher than that of the surrounding seawater.

Abstract:

En reflétant une image plus ou moins fidèle du cerveau, l’endocrâne permet d’accéder au système nerveux des espèces fossiles. A partir de spécimens exceptionnellement préservés de mosasaures (Squamata) et de plésiosaures (Sauropterygia), provenant des affleurements turoniens de Goulmima (sud du Maroc), ce travail a pour but de décrire, pour la première fois en détail l'anatomie endocrânienne de ces deux grands clades de reptiles marins du Mésozoïque. Cette étude a pour but d’inférer leurs capacités sensorielles permettant de comprendre leur cohabitation, leurs interactions et leur position au sein du réseau trophique. L'anatomie endocrânienne des squamates actuels, principalement des serpents mais aussi des varans et des amphisbènes, presque inconnus jusqu'à présent, a également été étudiée à des fins comparatives afin d’analyser les relations forme-fonction associées aux endocrânes. La variabilité morphologique de l’endocrâne chez les squamates actuel démontre un signal phylogénétique mais également écologique. De plus, la taille relative de chaque structure endocrânienne révèle des différences de vision et d'olfaction selon les espèces. Parmi les taxons fossiles, la microtomographie a été utilisée pour reconstituer en détail la morphologie crânienne de trois nouveaux spécimens de plésiosaures. Deux de ces spécimens ont été assignés à l’élasmosaure Libonectes morgani et le troisième à un polycotylidé indéterminé. La morphologie 3D de l'endocrâne a été reconstruite pour ces spécimens ainsi que pour le mosasaure basal Tethysaurus nopcsai. La morphologie endocrânienne des plésiosaures diffère de celles retrouvées chez les vertébrés éteints et actuels. En se basant sur la taille relative des structures composant leurs endocrânes, le mosasaure Tethysaurus et les plésiosaures semblent davantage utiliser la vision que l'olfaction pour interagir avec leur environnement. Ces nouvelles données endocrâniennes, ajoutées aux informations déjà disponibles dans la littérature, suggèrent différents modes de locomotion et techniques de chasse, ce qui leur a probablement permis de coexister à Goulmima en tant que prédateur
As windows into the deep history of neuroanatomy, endocasts may provide information about the central nervous system of fossil taxa. Based on exceptionally preserved specimens of coeval mosasauroids (Squamata) and plesiosaurians (Sauropterygia), from the Turonian outcrops of Goulmima (Southern Morocco), the aim of this work was to describe for the first time in detail the endocranial anatomy of these two major clades of Mesozoic marine reptiles to provide insights about their sensory abilities, and thus to understand their cohabitation, interactions and niche partitioning. The endocranial anatomy of related extant squamates, mainly snakes but also varanids and amphisbaenians, also almost unknown until now, has been performed for the first time and used for comparative purpose to analyze the form-function relationships associated to endocasts. The analysis of the endocranial variability in extant squamates pointed out that endocasts reflect both phylogenetic and ecological signals, and that the relative size of each endocranial structure can be used to reveal differences in vision and olfaction according to taxa. Among fossil taxa, computed tomography was used to reconstruct in detail the cranial morphology of three unpublished specimens of Plesiosauria. These specimens have been examined and described, two have been referred to the elasmosaurid Libonectes morgani and the third one is an indeterminate polycotylid. The 3D morphology of the endocast has been reconstructed for these plesiosaurian specimens and the basal mosasauroid Tethysaurus nopcsai. The results show that the endocranial morphology of Plesiosauria differs from that know in other extinct and extant vertebrates. Based on the relative size of the structures composing their endocasts, both the mosasauroid Tethysaurus and the plesiosaurians seem to rely more on vision than on olfaction to interact with their environment. However, these new endocast data, added to information already available in the literature suggest different modes of locomotion and hunting techniques, which probably allowed them to coexist in Goulmima as quaternary consumers

Abstract:

El estudio de la microestructura ósea proporciona información sobre ontogenia, estrategia de crecimiento y estilo de vida de los vertebrados tanto actuales como extintos. En los últimos años ha habido un notable incremento en el conocimiento de la paleobiología de los reptiles mesozoicos con base en el análisis de la microestructura ósea. No obstante, son aún extremadamente escasas las contribuciones referidas específicamente a reptiles marinos mesozoicos. Así, en el caso de los reptiles considerados como paradigmáticos de la adaptación secundaria al mar, los ictiosaurios, sólo se han publicado las descripciones de los húmeros de dos ejemplares de ictiosaurios tunosaurios del Jurásico Inferior de Holzmaden (Alemania). En este trabajo de tesis se estudia comparativamente la microestructura ósea de representantes de cuatro linajes de reptiles marinos–ictiosaurios, plesiosaurios plesiosauriomorfos, mosasaurios y tortugas marinas- registrados en el Jurásico y Cretácico de Patagonia e Islas de la Península Antártica. Como resultado se ha podido caracterizar el patrón microesqueletario de los taxones muestreados, en ejemplares de diferentes estadios ontogenéticos, y en diferentes huesos de un mismo esqueleto. La muestra seleccionada incluye doce ictiosaurios tunosaurios del Jurásico y Cretácico de Patagonia, siete plesiosaurios plesiosauriomorfos del Cretácico Tardío de Patagonia y Antártida, cuatro mosasaurios del Cretácico Superior de Antártida, y tres ejemplares de tortugas talasemídidas y panquelónidas. Los ictiosaurios tunosaurios analizados presentan un tejido óseo osteoporótico liviano tanto en formas juveniles como adultas, tal como había sido descripto en los dos ejemplares del Jurásico de Holzmaden (Alemania). Dado que se desconoce la microestructura ósea de los ictiosaurios basales, no es posible establecer si este patrón hallado en los tunosaurios es característico de este clado (lo que implicaría que habría acompañado a la adquisición de un nado tuniforme); o si por el por el contrario este patrón ya estaba presente en los ictiosaurios basales de nado anguiliforme. La especie Mollesaurus periallus presenta un patrón histológico paquiosteosclerótico, siendo este el primer registro de un ictiosaurio presentando este patrón de microestructura ósea. En los plesiosaurios plesiosauromorfos se encontraron dos tipos diferentes de microestructura ósea de acuerdo con el grado de compactación (paquiostótico y osteoporótico). Estas condiciones han sido mencionadas como indicativas del estadio ontogenético (juveniles vs adulto respectivamente). No obstante, como resultado de esta tesis, y en contraposición a lo publicado por otros autores, se indica que el grado de compactación no puede ser tomado en forma aislada, dado que, en al menos dos individuos de plesiosaurios plesiosauromorfos, el grado de compactación difiere de acuerdo con el hueso que se esté analizando. En uno de estos ejemplares se observó que la remodelación seria más temprana en costillas y gastralias que en las falanges. La microestructura ósea de las tortugas analizadas (Neusticemys neuquina y Euclastes meridionalis) es congruente con el patrón descripto para tortugas completamente acuáticas (histomorfo III) tales como Ctenochelys cf. C. stenoporus, Allopleuron hofmanni, Dermochelys coriacea. Las tortugas marinas muestran un patrón de hueso lamelar, moderadamente vascularizado comparable al de las más recientes tortugas y cocodrilos. Esta estructura también indica tasas de crecimiento relativamente más lentas en comparación con las de los ictiosaurios. En los mosasaurios se reconocen dos patrones en cuanto al grado de compactación que no es referible al estado ontogenético sino al modo de vida (i. e., ubicación en la columna de agua). El estudio comparativo de la microestructura ósea permitió estimar tasas de crecimiento relativas entre distintos linajes. En la muestra analizada, los ictiosaurios presentaron un patrón típico de una tasa de crecimiento extremadamente rápida, en tanto que las tortugas tendrían la tasa de crecimiento más lenta. Por primera vez se pudo establecer un orden relativo en cuanto a la tasa de crecimiento, siendo los ictiosaurios las formas con una tasa de crecimiento extremadamente rápida y siguiendo un orden decreciente estarían mosasaurios, plesiosaurios plesiosauromorfos, y, finalmente, con una la tasa más lenta de crecimiento, las tortugas. Si bien todos los ejemplares analizados eran formas de hábitos marinos, la microestructura ósea difiere de acuerdo con el grupo al que pertenecen. Como resultado de un extenso desarrollo de tejido óseo osteoporótico, el hueso de un ictiosaurio es liviano, lo que puede haber contribuido a una mayor maniobrabilidad en aguas abiertas. Esta estructura es comparable a la de la mayoría de las ballenas y delfines actuales. El patrón de la microestructura ósea de los plesiosaurios analizados coincide con el descripto para los plesiosaurios juveniles y adultos del Cretácico Superior de Nueva Zelanda y Antártida. La predominancia de tejido paquiostótico en plesiosaurios juveniles y osteoporótico en adultos ha sido correlacionada con el tipo de vida. En los plesiosaurios juveniles, la presencia de un esqueleto proporcionalmente más pesado se ha relacionado con hábitos de vida predominantemente costeros, en tanto que en adultos, el alivianamiento del esqueleto ha sido correlacionado con modos de vida pelágicos. Por su parte, la estructura osteohistológica de algunos géneros de mosasaurios presentan un tejido óseo pesado, y la de otros géneros un tejido óseo liviano. Esto permite interpretar que los mosasaurios podían habitar diferentes regiones de la columna de agua, lo que implica que tenían diferentes estilos de vida, hábitos buceadores y tasas de crecimiento. También se ha desarrollado en el presente trabajo de tesis una investigación sobre el estado madurativo de los individuos, pudiendo establecer edades relativas para diferentes individuos de los cuatro linajes estudiados contando con un criterio auxiliar a la hora de establecer edades relativas cuando no se cuenta con el material completo.

Abstract:

The purpose of the Sternberg Museum-Forsyth Library Fossil Digitization Pilot Project was to determine the feasibility of conducting a large-scale fossil digitization program at Fort Hays State University, Hays, Kansas. Conducted in early 2011, the pilot examined such aspects as fossil digitization techniques, metadata development and best practices, scope and timelines, and overall digitization goals. This chapter focuses on the digitization landscape of the natural sciences, including an overview of major fossil digitization projects and analyses of issues related to these projects. Conclusions from the Sternberg-Forsyth pilot are also recounted and discussed. Also included is an appendix outlining costs and time needed for the recommended small-scale digitization project that will begin in late 2011 or early 2012.
