ABSTRACT Here we describe the most plesiomorphic koala yet known. Priscakoala lucyturnbullae, gen. et sp. nov., is the fourth and largest koala species described from Miocene deposits in the Riversleigh World Heritage area, northern Australia. It is known from a maxilla with M1–3 and isolated M2, M3 or M4 and m1. Relationships within the diprotodontian suborder Vombatiformes are clarified using cranial and dental characters based on a data set compiled from new and more complete cranial… 
New genus of primitive wombat (Vombatidae, Marsupialia) from Miocene deposits in the Riversleigh World Heritage Area (Queensland, Australia)
A phylogenetic analysis incorporating the new genus of primitive wombat and using dental, cranial and postcranial characters as well as multiple outgroups indicates a sister relationship between the new taxon and R. crowcrofti relative to all other wombats.
A new family of diprotodontian marsupials from the latest Oligocene of Australia and the evolution of wombats, koalas, and their relatives (Vombatiformes)
It is suggested that the highly derived vombatids evolved from wynyardiid-like ancestors, and that scratch-digging adaptations evolved in vombatoids prior to the appearance of the ever-growing (hypselodont) molars that are a characteristic feature of all post-Miocene vombatid species.
Lekaneleo, a New Genus of Marsupial Lion (Marsupialia, Thylacoleonidae) from the Oligocene–Miocene of Australia, and the Craniodental Morphology of L. roskellyae, comb. nov.
The domestic cat-sized marsupial lion Priscileo roskellyae (Thylacoleonidae) from the Oligocene–Miocene of Australia is described, which is a relatively conservative taxon, exhibiting no discernible change over the same interval of time.
Middle Miocene origins for tough-browse dietary specialisations in the koala (Marsupialia, Phascolarctidae) evolutionary tree: description of a new genus and species from the Riversleigh World Heritage Area
Dental specialisations of Stelakoala riversleighensis include a high molar crown, the presence of large accessory blades and cuspids, and the development of lingual ribs on the entoconid and metaconid, which may represent an early stage in the transition to a more fibrous, highly specialised diet in the evolutionary history of koalas.
Revision of basal macropodids from the Riversleigh World Heritage Area with descriptions of new material of Ganguroo bilamina Cooke, 1997 and a new species
A new species from the Bitesantennary Site within the Riversleigh's World Heritage Area is described, new cranial and dental material of G. bilamina is reported, and the current understanding of basal macropodid diversity in Oligocene and Miocene sites at Riversleigh WHA is revised.
A reassessment of the genus Groeberia Patterson, 1952 (Mammalia, Metatheria): functional and phylogenetic implications
A cladistic analysis resulted in the inclusion of Groeberia among australidelphian metatherians, clustering with vombatiform diprotodontians in the strict consensus tree; however, these affinities require further testing.
A new species of Miocene wombat (Marsupialia, Vombatiformes) from Riversleigh, Queensland, Australia, and implications for the evolutionary history of the Vombatidae
A new species of wombat, Rhizophascolonus ngangaba sp. nov., is described from Miocene deposits at Riversleigh along with additional specimens of Rhizo-phascolonus crowcrofti, and some maxillary and
The Rise of Australian Marsupials: A Synopsis of Biostratigraphic, Phylogenetic, Palaeoecologic and Palaeobiogeographic Understanding
The origins, evolution and palaeodiversity of Australia’s unique marsupial fauna are reviewed. Australia’s marsupial fauna is both taxonomically and ecologically diverse comprising four extant orders
The Chinchilla Local Fauna: An Exceptionally Rich and Well-Preserved Pliocene Vertebrate Assemblage from Fluviatile Deposits of South-Eastern Queensland, Australia
The Chinchilla Sand is a formally defined stratigraphic sequence of Pliocene fluviatile deposits that comprise interbedded clay, sand, and conglomerate located in the western Darling Downs,
Herds Overhead: Nimbadon lavarackorum (Diprotodontidae), Heavyweight Marsupial Herbivores in the Miocene Forests of Australia
The appendicular skeleton of Nimbadon lavarackorum is described and functionally analyse and suggests adept climbing ability, probable suspensory behaviour, and an arboreal lifestyle for this plesiomorphic and smallest of diprotodontids.


A new koala (Marsupialia:Phascolarctidae) from the late Oligocene Etadunna Formation, Lake Eyre Basin, South Australia
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
Invictokoala monticola gen. et sp. nov. (Phascolarctidae, Marsupialia), a Pleistocene plesiomorphic koala holdover from Oligocene ancestors
Koalas (Phascolarctidae) are uncommon elements within the Australian fossil record. The earliest representatives are recorded from late Oligocene rainforest assemblages of central Australia. In
Descriptions of koala fossils from the Miocene of Riversleigh, northwestern Queensland and implications for Litokoala (Marsupialia, Phascolarctidae)
The dentition of a partial skull of Litokoala from Jims Carousel Site, System C is described and it is suggested that the morphological variation between L. kutjamarpensis Stirton, 1967 and L. kanunkaensis Springer, 1987 does not warrant specific distinction.
Maradidae: a new family of vombatomorphian marsupial from the late Oligocene of Riversleigh, northwestern Queensland
Although known from only a single dentary, Marada is assigned to a new family Maradidae, based on a unique combination of both plesiomorphic and apomorphic features, which is most similar to primitive wynyardiids and diprotodontoids.
Description of new material for Propalorchestes novaculacephalus (Marsupialia: Palorchestidae) from the mid Miocene of Riversleigh, northwestern Queensland
Additional material referable to Propalorchestes novaculacephalus from System B and System C deposits from the Riversleigh World Heritage Area, northwestern Queensland, is described. One of these
The degree of morphological difference between species of Durudawiri and Miralina suggests subfamilial distinction for the two groups, and 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 cusp on the buccal shelf.
Neohelos stirtoni, a new species of Zygomaturinae(Diprotodonta: Masupialia) from the mid-Tertiary of the Northern Territory, Australia
Neohelos stirtoni is an excellent structural intermediate between the most plesiomorphic midTertiary zygomaturines and the late Miocene-early Pliocene genus Kolopsis, and provides useful insights for interpretation of highly derived anatomical features of lateMiocene-Pleistocene Zygomaturus species.
New records of Plio-Pleistocene koalas from Australia: palaeoecological and taxonomic implications
This work provides the first unambiguous evidence of koalas in the Pliocene Chinchilla Local Fauna (phascolarctid indet. and Ph. ?stirtoni), important additions to an increasingly diverse arboreal mammalian assemblage that also includes tree kangaroos.

The skull of Ekaltadeta ima (Marsupialia, Hypsiprymnodontidae?): An analysis of some marsupial cranial features and a re-investigation of propleopine phylogeny, with notes on the inference of carnivory in mammals
Preliminary results of investigation into dietary habitus indicate that Propleopinae represents a radiation of medium- to large-sized omnivorous kangaroos, and it is reiterated that a tendency toward carnivory might be inferred from the relative importance of high amplitude vertical shearing versus horizontal shearing and/or crushing elements in the dentition.
