Abstract Since the frst discoveries of megafauna fossils in the Wellington Valley of New South Wales in the 1830s, caves have featured prominently in the study of Quaternary Australia. Today, most of the well-dated, strati- fed Quaternary megafauna sites are known from caves. Tis refects the relatively stable preservation environment within Australian caves, where skeletal remains may lay undisturbed for hundreds of thousands of years. -

Marsupial Lions & Methodological Omnivory
Marsupial Lions & Methodological Omnivory: Function, Success and Reconstruction in Paleobiology Penultimate Version, published in Biology & Philosophy Abstract Historical scientists frequently face incomplete data, and lack direct experimental access to their targets. This has led some philosophers and scientists to be pessimistic about the epistemic potential of the historical sciences. And yet, historical science often produces plausible, sophisticated hypotheses. I explain this capacity to generate knowledge in the face of apparent evidential scarcity by examining recent work on Thylacoleo carnifex, the ‘marsupial lion’. Here, we see two important methodological features. First, historical scientists are methodological omnivores, that is, they construct purpose-built epistemic tools tailored to generate evidence about highly specific targets. This allows them to produce multiple streams of independent evidence and thus maximize their epistemic reach. Second, investigative scaffolding: research proceeds in a piece-meal fashion, information only gaining evidential relevance once certain hypotheses are well supported. I illustrate scaffolding in a discussion of the nature of functional ascription in paleobiology. Frequently, different senses of ‘function’ are not discriminated during paleobiological investigation—something which can mar adaptationist investigations of extant organisms. However, I argue that, due to scaffolding, conflating senses of ‘function’ can be the right thing to do. Coarse grained functional hypotheses are required before it is clear what evidence could discriminate between more fine-grained ones. I draw on omnivory and scaffolding to argue that pessimists make a bad empirical bet. It is a bad idea to bet against the epistemic fortunes of such opportunistic and resourceful scientists, especially when we have reason to think we will systematically underestimate the amount of evidence ultimately available to them. -

THYLACOLEO CARNIFEX and the NARACOORTE CAVES Michael Curry, Liz Reed1,2 and Steve Bourne3

It is the extreme modification, to this end, of the Diprotodont type of Marsupialia.” Owen (1866) Introduction defending Thylacoleo as “A very gentle beast, and of good conscience” (Macleay 1859).

Perhaps it is the allure of its predatory almost equally as unimpressed with Thylacoleo’s habits, (Australia’s Pleistocene answer to T. rex); or the carnivory, opining that it “…was not much more intriguing notion that it used caves as dens (Lundelius, carnivorous than the Phalangers (possums) of present 1966 ). It is certainly an enigma and, as Owen (1866) time.” (Krefft, 1866).

Australia's Lost Giants
Reading Australia’s Lost Giants What happened to Australia’s megafauna, the giant animals that once existed across this enormous continent? A In 1969, a fossil hunter named Rod Wells came to Naracoorte in South Australia to explore what was then known as Victoria Cave. Wells clawed through narrow passages, and eventually into a huge chamber. Its floor of red soil was littered with strange objects. It took Wells a moment to realize what he was looking at; the bones of thousands of creatures that must have fallen through holes in the ground above and become trapped. Some of the oldest belonged to mammals far larger than any found today in Australia. They were the ancient Australian megafauna – huge animals of the Pleistocene epoch. In boneyards across the continent, scientists have found the fossils of a giant snake, a huge flightless bird, and a seven foot kangaroo, to name but a few. Given how much ink has been spilled on the extinction of the dinosaurs, it’s a wonder that even more hasn’t been devoted to megafauna. Prehistoric humans never threw spears at Tyrannosaurus rex but really did hunt mammoths and mastodons. B The disappearance of megafauna in America – mammoths, saber-toothed cats, giant sloths, among others – happened relatively soon after the arrival of human beings, about 13,000 years ago. In the 1960s, paleoecologist Paul Martin developed what became known as the blitzkrieg hypothesis. Modern humans, Martin said, created havoc as they spread through the Americas, wielding spears to annihilate animals that had never faced a technological predator. -

Kangaroo populations experience large fluctuations in size. Early research suggested that rainfall was a good predictor of population changes through its effect on per capita food availability. Population dynamics of large herbivores, however, are likely influenced by interactions between stochastic environmental variation and density dependence. Vital rates can respond differently to environmental variation and to changes in density. In particular, juvenile survival is most sensitive to harsh conditions, and adult survival rarely affected. Consequently, an improved understanding of population dynamics requires monitoring of individuals of known sex and age under a variety of environmental conditions. I will investigate how density, age structure and environmental conditions affect the population dynamics of eastern grey kangaroos (Macropus giganteus) at Wilsons Promontory National Park, Victoria, where >1200 individuals of known age and sex have been monitored since 2008. I will test the hypothesis that environmental conditions and density dependence have interacting and age-specific roles in generating changes in population size. -
A New Family of Diprotodontian Marsupials from the Latest Oligocene of Australia and the Evolution of Wombats, Koalas, and Their Relatives (Vombatiformes) Robin M
www.nature.com/scientificreports OPEN A new family of diprotodontian marsupials from the latest Oligocene of Australia and the evolution of wombats, koalas, and their relatives (Vombatiformes) Robin M. D. Beck1,2 ✉ , Julien Louys3, Philippa Brewer4, Michael Archer2, Karen H. Black2 & Richard H. Tedford5,6 We describe the partial cranium and skeleton of a new diprotodontian marsupial from the late Oligocene (~26–25 Ma) Namba Formation of South Australia. This is one of the oldest Australian marsupial fossils known from an associated skeleton and it reveals previously unsuspected morphological diversity within Vombatiformes, the clade that includes wombats (Vombatidae), koalas (Phascolarctidae) and several extinct families. Several aspects of the skull and teeth of the new taxon, which we refer to a new family, are intermediate between members of the fossil family Wynyardiidae and wombats. Its postcranial skeleton exhibits features associated with scratch-digging, but it is unlikely to have been a true burrower. Body mass estimates based on postcranial dimensions range between 143 and 171 kg, suggesting that it was ~5 times larger than living wombats. Phylogenetic analysis based on 79 craniodental and 20 postcranial characters places the new taxon as sister to vombatids, with which it forms the superfamily Vombatoidea as defned here. It suggests 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 vombatids. Ancestral state reconstructions on our preferred phylogeny suggest that bunolophodont molars are plesiomorphic for vombatiforms, with full lophodonty (characteristic of diprotodontoids) evolving from a selenodont morphology that was retained by phascolarctids and ilariids, and wynyardiids and vombatoids retaining an intermediate selenolophodont condition. -

Marshall Zoology Department, Monash University, Victoria* Abstract Fossil vertebrate localities and faunas in the Lake Victoria region of S.W. New South Wales, Australia, are described. The oldest fossil bearing deposit, the late Pliocene or early Pleistocene Moorna Formation and associated Chowilla Sand have yielded specimens of Neoceratodus sp., Emydura macquarrii, several species of small dasyurid, specimens of Glaucodon cf. G. ballaratensis, a species of Protemnodon which compares closely with P. cf. P. otibandus from the late Pliocene or early Pleistocene Chinchilla Sand in SE. Queensland, specimens of Lagostrophus cf L. fasciatus, species of Petrogale, Macropus, Osphranter, Sthenurus, Bettongia, Diprotodon, Lasiorhinus, a peramelid, at least two species of pseudomyine rodents and a species of Rattus cf. R. lutreolus. It is shown that the holotype of Zygomaturus victoriae (Owen) 1872 may have been collected from these sediments. The late Pliocene or early Pleistocene Blanchetown Clay has yielded species of Neoceratodus, Thylacoleo, Phas- colonus, Bettongia, Sthenurus, a diprotodontid, and a rodent. The late Pleistocene Rufus Formation has yielded species of Dasycercus, Sarcophilus, Thylacinus, Phascolonus, Lasiorhinus, Bettongia, Procoptodon, Onychogalea, Macropus, and Leporillus. A large species of macropod and a species of Phascolonus were collected from the late Pleistocene Monoman Formation. The lunette on the E. side of Lake Victoria has yielded a large, diverse fauna of late Pleistocene —Holocene age, that includes such extinct species as Protemnodon anak, P. brehus, Procoptodon goliah, Sthenurus andersoni, S.
