Developing a radiometrically-dated chronologic sequence for Neogene biotic change in Australia, from the Riversleigh World Heritage Area of Queensland
Abstract Radiometric U–Pb ages are presented for the Riversleigh World Heritage fossil mammal site in northwestern Queensland, Australia. The ages are determined on speleothems which are generallyExpand
Australia's Oldest Marsupial Fossils and their Biogeographical Implications
Djarthia is the oldest known crown-group marsupial anywhere in the world that is represented by dental, cranial and post-cranial remains, and is also the most plesiomorphic known australidelphian, and phylogenetic analyses place it outside all other Australian marsupials. Expand
Earliest known Australian Tertiary mammal fauna
The discovery of a tooth of the earliest non-volant placental known from Australia, Tingamarra porterorum gen.et sp. Expand
Fossil Mammals of Riversleigh, Northwestern Queensland: Preliminary Overview of Biostratigraphy, Correlation and Environmental Change
Aspects of the results of studies of the fossil-rich Cainozoic deposits of Riversleigh, northwestern Queensland, are reviewed. A summary of five selected Riversleigh faunas representing the primaryExpand
First discovery of monotremes in South America
The first monotreme from outside the Australian continent, an ornithorhyn-chid, is reported from sediments of late early Palaeocene age in Patagonia, southern Argentina, demonstrating the Gondwanan nature of monotremes and supporting the hypothesis that the Patagonian Terrane of southern South America had a biotic history distinct from that of the rest of the continent.

Miocene mammal reveals a Mesozoic ghost lineage on insular New Zealand, southwest Pacific
Its presence in NZ in the Middle Miocene and apparent absence from Australia and other adjacent landmasses at this time appear to reflect a Gondwanan vicariant event and imply persistence of emergent land during the Oligocene marine transgression of NZ. Expand
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 ordersExpand
Multivariate analyses of Cenozoic mammalian faunas from Riversleigh, northwestern Queensland
Mammalian faunal lists of Riversleigh fossil sites were compared using several techniques to assess the age relationships between 75 Riversleigh sites and the central Australian Ngama, Kutjamarpu andExpand
Biogeographical and Phylogenetic Implications of an Early Miocene Wren (Aves: Passeriformes: Acanthisittidae) from New Zealand
A phylogenetic analysis of 53 osteological characters and 24 terminal taxa recovers a similar pattern of relationships of basal corvoid taxa to that obtained by recent molecular studies, suggesting that the radiation of Recent acanthisittids originated no later than the Early Miocene. Expand
