Abstract:

Two new species of megadermatid bats (Macroderma godthelpi and an unnamed taxon) are described from middle Miocene limestone deposits on Riversleigh Station, northwestern Queensland and their probable phylogentic positions within the Megadermatidae are discussed. The new Riversleigh species appear to be representatives of two separate megadermatid lineages. Consideration is given to the significance of the Australian forms within a world context. The Riversleigh material has also prompted a re-evaluation of morphological characters used to determine limits for fossil megadermatids. To facilitate this assessment, size and morphological variation present in Australia's Recent megadermatid, Macroderma gigas, have been investigated.

Abstract:

The Giant Rat Kangaroos (Ekaltadeta, Propleopus) were placed in a new subfamily the Propleopinae by Archer and Flannery (1985). The discovery of new Ekaltadeta material from Riversleigh, northwestern Queensland has stimulated a review of propleopine phylogeny. Cladistic analysis of five propleopine taxa suggests possible paraphyly for Ekaltadeta and polyphyly for Propleopus. A new species of Miocene propleopine, Ekaltadeta jamiemulvaneyi n. sp., from system C local faunas at Riversleigh, is described.

Full text

Abstract:

Thylacinus macknessi is described from Miocene sediments of Riversleigh, northwestern Queensland. Comparisons with other thylacinids and dasyurids reveal it to be a new species of Thylacinus. In most features it is as specialised as T. cynocephalus and it is not considered to be ancestral to any other taxon. The presence of such a specialised thylacine in the Riversleigh deposits argues for a pre-Late Oligocene divergence of this group from the Dasyuridae.

Abstract:

Yarala burchfieldi n. gen. and sp. is described from Oligo-Miocene deposits of Riversleigh Station, northwestern Queensland. Although the smallest and most plesiomorphic bandicoot known, it shares unique synapomorphies with other peramelemorphs, such as the posteriorly orientated preparacrista on M2, posterolingual location of the hypoconulids, and the buccal position of the centrocrista. However, Y. burchfieldi lacks synapomorphies that would unambiguously allow it to be placed in any of the modern families as currently understood. In its plesiomorphic features, Y. burchfieldi provides a structural link between peramelemorphs and dasyuromorphs and appears to be a descendant of an annectant group that separated long prior to the origin of “typical” bandicoots. This species is present in many sites within the Riversleigh area. It possibly filled an insectivorous-carnivorous niche presently occupied by small dasyurids that are relatively more abundant today than they were when the Riversleigh deposits accumulated.

Abstract:

Extinct species of Malleodectes gen. nov. from Middle to Late Miocene deposits of the Riversleigh World Heritage Area, northwestern Queensland, Australia are enigmatic, highly specialized, probably snail-eating marsupials. Dentally, they closely resemble a bizarre group of living heterodont, wet forest scincid lizards from Australia ( Cyclodomorphus ) that may well have outcompeted them as snail-eaters when the closed forests of central Australia began to decline. Although there are scincids known from the same Miocene deposits at Riversleigh, these are relatively plesiomorphic, generalized feeders. This appears to be the most striking example known of dental convergence and possible competition between a mammal and a lizard, which in the long run worked out better for the lizards.

Abstract:

Fourteen of the best sampled Oligo-Miocene local faunas from the Riversleigh World Heritage Area, north-western Queensland, Australia are analysed using classification and ordination techniques to identify potential mammalian palaeocommunities and palaeocommunitytypes. Abundance data for these faunas are used, for the first time, in conjunction with presence/absence data. An early Miocene Faunal Zone B and two middle Miocene Faunal Zone C palaeocommunities are recognised, as well as one palaeocommunity type. Change in palaeocommunity structure, between the early Miocene and middle Miocene, may be the result of significant climate change during the Miocene Carbon Isotope Excursion. The complexes of local faunas identified will allow researchers to use novel palaeocommunities in future analyses of Riversleigh’s fossil faunas. The utility of some palaeoecological multivariate indices and techniques is examined. The Dice index is found to outperform other binary similarity/distance coefficients, while the UPGMA algorithm is more useful than neighbour joining. Evidence is equivocal for the usefulness of presence/absence data compared to abundance.

Journal of Paleontology 70, no. 6 (November 1996): 1032–44. http://dx.doi.org/10.1017/s0022336000038737.

Full text

Abstract:

A new genus and species of thylacinid, Muribacinus gadiyuli, is described from Miocene deposits of Riversleigh in northwestern Queensland. Muribacinus gadiyuli shares six character states associated with carnassialisation common among thylacinids, but is uniformly less derived for each. The closest affinities of this species lie with another plesiomorphic thylacinid from Riversleigh, Nimbacinus dicksoni. Two previously recognised thylacinid synapomorphies are reconsidered in the light of new evidence. A growing body of molecular and fossil data indicates that the modern dasyurid radiation is a relatively recent phenomenon. Character analysis suggests that no reliable dental synapomorphies define the Dasyuridae at present. It is proposed that a number of plesiomorphic late Oligocene and Miocene taxa previously considered as dasyurids be regarded as Dasyuromorphia incertae sedis pending the identification of shared derived dental characters for the family, or the discovery of more complete material.

Abstract:

FOUR fossil peramelemorphians are currently recognised ? Yarala burchfieldi from Miocene deposits of Riversleigh (Muirhead and Filan 1995; Muirhead in press), Ischnodon australis from the Early to Middle Pliocene Palankarinna Fauna (Stirton 1955), Perameles allinghamensis from the Early Pliocene Bluff Downs Local Fauna (Archer 1976) and P. bowensis from the Early Pliocene Bow Local Fauna (Muirhead et al. 1997). Three of these fossil taxa are referable to modern families. Ischnodon australis represents the Thylacomyidae, while Perameles allinghamensis and P. bowensis represent the Peramelidae. Yarala burchfieldi, in contrast, represents the superfamily Yaraloidea (Muirhead in press).

Abstract:

Fossil plant organs from probable Oligocene nodules at the Dunsinane Site at Riversleigh, Queensland, were studied. The deposit consists of a low diversity assemblage of reproductive and vegetative organs dominated by a single taxon of Casuarinaceae. The species of Casuarinaceae has affinities with Casuarina and Allocasuarina in having more four teeth per whorl on the photosynthetic branchlets and stomata hidden in deep furrows filled with trichomes, and as such represents the earliest known record of sub-family Cryptostomae. The species is described as Cryptostomiforma quinata gen. et sp. nov. A leaf species is assigned to Alectryon (Sapindaceae) on the basis of the anatomy of abaxial cuticular features. In particular, the morphology is indistinguishable from extant A. affinis, a species currently endemic to New Guinea. Organs with possible affinities to Rubus or Capparis were examined. The assemblage is interpreted as a possible vegetation mosaic, containing both deciduous vine thickets and sclerophyllous habitats. No evidence for the presence of rainforest was found and the fossils are not consistent with extensive lowland tropical rainforest.

Abstract:

A new species, Balbaroo fangaroo, of balbarine kangaroo is described from the freshwater limestone deposits at Riversleigh northern Australia. The type specimens include two partial skulls which reveal hitherto unknown characters of Balbarinae and provide new evidence relevant to the resolution of the phylogenetic affinities of Balbarinae. A number of the newly-revealed characters e.g., squamosal-frontal contact on the walls of the neurocranium, are argued as being plesiomorphic for Macropodoidea.Hypertrophied upper canines which occur in the paratype, have never previously been recorded in kangaroos and represent an example of evolutionary convergence between these herbivorous marsupials and ungulate eutherians.

Abstract:

The early Miocene Durudawiri inusitatus new genus and species (Marsupialia: Phalangeroidea) is described from the Riversleigh World Heritage Property in northwestern Queensland. It appears to represent the plesiomorphic sister group of the late Oligocene species of Miralina from South Australia. Its molar morphology is not as complex as that of species of Miralina or ektopodontids, but it is more complex than that of phalangerids. The degree of morphological difference between species of Durudawiri and Miralina suggests subfamilial distinction for the two groups. Strange cusps on the upper molars could be interpreted as either large neometaconules and paraconules, or lingually-displaced metacones and paracones with very large stylar cusps on the buccal shelf.

Abstract:

A new genus and three new species of the microchiropteran family Mystacinidae are described from Miocene freshwater limestones in northern Australia. The type species,Icarops brevicepsnew genus and species, is from the middle Miocene Bullock Creek deposit, Northern Territory;I. aenaenew species andI. paradoxnew species are from the slightly older (early Miocene) Wayne's Wok and Neville's Garden Sites at Riversleigh, northwestern Queensland. Fossil mystacinids are rare in each deposit and represented so far only by lower teeth and dentary fragments. They are characterized by a suite of apomorphies shared only with Quaternary mystacinids endemic to New Zealand. The family Mystacinidae has no pre-Pleistocene record and its relationships to other groups of bats remain unclear. Possible sister-groups include South American noctilionoids and the cosmopolitan molossoids and/or vespertilionoids. The presence of plesiomorphic mystacinids in the Australian Tertiary suggests an Australian origin for the family.

Abstract:

Sheath-tailed bats (Family Emballonuridae) from the early Pleistocene Rackham’s Roost Site cave deposit in the Riversleigh World Heritage Area, north-western Queensland are the oldest recorded occurrence for the family in Australia. The fossil remains consist of maxillary and dentary fragments, as well as isolated teeth, but until now their precise identity has not been assessed. Our study indicates that at least three taxa are represented, and these are distinguished from other Australian emballonurids based on morphometric analysis of craniodental features. Most of the Rackham’s Roost Site emballonurid remains are referrable to the modern species Taphozous georgianus Thomas, 1915, but the extant species T. troughtoni Tate, 1952 also appears to be present, as well as a very large, as-yet undetermined species of Saccolaimus Temminck, 1838. We identify craniodental features that clearly distinguish T. georgianus from the externally very similar T. troughtoni. Results suggest that the distributions of T. georgianus and T. troughtoni may have overlapped in north-western Queensland since at least the early Pleistocene.

Abstract:

A partial skeleton (including both skull and postcranium) and referred dental material attributable to a new species of Oligo-Miocene kangaroo, Nambaroo gillespieae, are described from the Riversleigh World Heritage Area, northwestern Queensland, Australia. The holotype specimen is one of the oldest articulated fossil kangaroo skeletons yet discovered and includes the first postcranial material definitively attributable to the extinct family Balbaridae. Functional-adaptive analysis (including comparisons with modern taxa) of the hindlimb and pedal elements suggests consistent use of quadrupedal progression rather than true hopping. Robust forelimbs and an opposable first pedal digit (lost in most macropodoids) might also indicate limited climbing ability. Cladistic analysis of 104 discrete cranio-dental and postcranial characters coded for 25 ingroup and one outgroup taxon places N. gillespieae in a plesiomorphic sister clade (also containing other Balbarids and the propleopine Ekaltadeta ima) to all other macropodoids. This result supports recent revisions to the classification of kangaroos, which recognize Balbaridae as the most basal macropodoid family-level taxon.

Abstract:

An eighth genus and twelfth species of Tertiary thylacinid is described. This new taxon represents the seventh member of the family from the fossiliferous Carl Creek limestones of Riversleigh, north-western Queensland. Although plesiomorphic within Thylacinidae regarding most features and lacking synapomorphies that unambiguously unite it with specialised taxa within the family, it possesses two autapomorphies. With an estimated body weight of around 18 kg it is also larger than any previously known thylacinid predating the late Miocene. Body-weight estimates for remaining fossil Thylacinidae span a wide range from just over 1 kg to almost 60 kg. While the smallest species is comparable to the extant Dasyurus viverrinus in size, most (i.e. 9 of 12 taxa) are at least twice the average size of the living Dasyurus maculatus. These results suggest that trophic diversity among thylacinids is even greater than previously thought and detract from the argument that reptiles have dominated large terrestrial carnivore niches in Australia since at least early Miocene times.

Abstract:

An isolated upper molar represents Litokoala thurmerae sp. nov., the eighth species of phascolarctid marsupial (koalas) from the South Australian mid-Tertiary sequence, and the fourth from the late Oligocene Etadunna Formation at Lake Palankarinna. It is the smallest and oldest species, differing from L. kutjamarpensis (Stirton et al. 1967), L. kanunkaensis (Springer 1987) and L. dicktedfordi, sp. nov. (the Riversleigh specimens referred to L. kanunkaensis and L. kutjamarpensis (Black and Archer 1997; Louys et al. 2007) but described here as a new species) in size, and the almost total lack of crenulations on the surfaces of the cusps. This brings to at least five the number of probably arboreal mammal species in the Ngama Local Fauna (Pledge 1984) of Mammalon Hill, Lake Palankarinna – the others being Ektopodon stirtoni (Pledge 1986), Pildra magnus (Pledge 1987a), P. sp. cf. kutjamarpensis (ibid.), and Burramys wakefieldi (Pledge 1987b) – and further supports the riparian forest environment interpretation proposed for this part of the Etadunna sequence (Pledge 1984; Martin 2006).
