AUSTRALIA'S second Mesozoic mammal, Kollikodon ritchiei (Monotremata, Kollikodontidae, new family) has an extreme bunodont molar morphology. The existence of two distinctively different families of monotremes in the Early Cretaceous suggests that the order originated long before the Cretaceous and was very diverse in at least the Australian portion of eastern Gondwana. With four families now known from Australia, it is probable that monotremes originated and diversified in the Australian…

First monotreme from the Late Cretaceous of South America

An isolated tooth from the Late Cretaceous of Argentina indicates a monotreme presence in South America by the end of the Mesozoic. Monotremata is a clade of egg-lying mammals, represented by the…

An Australian Multituberculate and Its Palaeobiogeographic Implications

A dentary fragment containing a tiny left plagiaulacoid fourth lower premolar from the Early Cretaceous (Aptian) of Victoria provides the first evidence of the Multituberculata from Australia. This…

A tribosphenic mammal from the Mesozoic of Australia.

A small, well-preserved dentary of a tribosphenic mammal with the most posterior premolar and all three molars in place has been found in Aptian (Early Cretaceous) rocks of southeastern Australia. In…

A review of monotreme (Monotremata) evolution

Abstract Advances in dating and systematics have prompted a revision of monotreme evolution to refine the timing of adaptative trends affecting body size and craniodental morphology. The oldest known…

AN ENIGMATIC (SYNAPSID?) TOOTH FROM THE EARLY CRETACEOUS OF NEW SOUTH WALES, AUSTRALIA

Abstract Largely fragmentary fossils from sites in New South Wales, Victoria, and Queensland, Australia document terrestrial and marine vertebrate faunas of Aptian–Albian age. The natural cast of a…

A large-clawed theropod (Dinosauria: Tetanurae) from the Lower Cretaceous of Australia and the Gondwanan origin of megaraptorid theropods

After the deluge: mitochondrial DNA indicates Miocene radiation and Pliocene adaptation of tree and giant weta (Orthoptera: Anostostomatidae)

It is hypothesize that at least three distinct groups of weta survived the Oligocene marine transgression and radiated subsequently, and patterns of genetic diversity within species reflect, in some instances, geographical subdivision in the Pliocene, and in other cases, Pleistocene range changes resulting from climate change.

Spoochelys ormondea gen. et sp. nov., an Archaic Meiolaniid-Like Turtle from the Early Cretaceous of Lightning Ridge, Australia

The persistence of surprisingly archaic taxa such as Spoochelys into the Early Cretaceous of Australia implies survival of an ancient Pangean lineage, and brings into question long-held assumptions of Laurasian affinities for the meiolaniid-like turtles of Gondwana.

A new non-marine Early Cretaceous gastropod species from Lightning Ridge, New South Wales

A new species of thiarid snail attributable to the extant genus Melanoides is described from the Early Cretaceous (middle-late Albian) non-marine deposits of the Griman Creek Formation at Lightning…

A New, Giant Platypus, Obdurodon tharalkooschild, sp. nov. (Monotremata, Ornithorhynchidae), from the Riversleigh World Heritage Area, Australia

This species is the largest known ornithorhynchid, fossil or extant, the fourth extinct platypus described, and the second species discovered at Riversleigh, Australia, and exhibits a unique molar morphology that significantly broadens understanding about disparity within this group of monotremes.

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.

A second Cretaceous mammalian specimen from Lightning Ridge, N.S.W., Australia

The recognition of a second mammalian specimen regarded as coming from the Early Cretaceous Griman Creek Formation at Lightning Ridge, N.S.W., Australia corroborates the provenance of the holotype of Steropodon galmani, an edentulous maxilla with multiple-rooted cheekteeth.

Reconsideration of Monotreme Relationships Based on the Skull and Dentition of the Miocene Obdurodon dicksoni

The anatomy of a complete skull, posterior half of a dentary, and cheektooth dentition of a Miocene ornithorhynchid, Obdurodon dicksoni from Riversleigh, Queensland, Australia is described and this new information is used to reevaluate understanding of the anatomy of the living OrnithorHynchus anatinus.

Toward a Phylogenetic Classification of the Mammalia

This short paper attempts to update certain aspects of my previous review by taking into account research published since 1969, as well as work being incorporated into a new classification of the Mammalia now being prepared which wall deal with all taxonomic levels down to the subgeneric level in essentially the same style as Simpson’s (1945) classification.
