Abstract:
Fossils of a marsupial mole (Marsupialia, Notoryctemorphia, Notoryctidae) are described from early Miocene deposits in the Riversleigh World Heritage Area, northwestern Queensland, Australia. These represent the first unequivocal fossil record of the order Notoryctemorphia, the two living species of which are among the world's most specialized and bizarre mammals, but which are also convergent on certain fossorial placental mammals (most notably chrysochlorid golden moles). The fossil remains are genuinely ‘transitional', documenting an intermediate stage in the acquisition of a number of specializations and showing that one of these—the dental morphology known as zalambdodonty—was acquired via a different evolutionary pathway than in placentals. They, thus, document a clear case of evolutionary convergence (rather than parallelism) between only distantly related and geographically isolated mammalian lineages—marsupial moles on the island continent of Australia and placental moles on most other, at least intermittently connected continents. In contrast to earlier presumptions about a relationship between the highly specialized body form of the blind, earless, burrowing marsupial moles and desert habitats, it is now clear that archaic burrowing marsupial moles were adapted to and probably originated in wet forest palaeoenvironments, preadapting them to movement through drier soils in the xeric environments of Australia that developed during the Neogene.

Abstract:
The fossil record provides important information about changes in species diversity, distribution, habitat and abundance through time. As we understand more about these changes, it becomes possible to envisage a wider range of options for translocations in a world where sustainability of habitats is under increasing threat. The Critically Endangered alpine/subalpine mountain pygmy-possum, Burramys parvus (Marsupialia, Burramyidae), is threatened by global heating. Using conventional strategies, there would be no viable pathway for stopping this iconic marsupial from becoming extinct. The fossil record, however, has inspired an innovative strategy for saving this species. This lineage has been represented over 25 Myr by a series of species always inhabiting lowland, wet forest palaeocommunities. These fossil deposits have been found in what is now the Tirari Desert, South Australia (24 Ma), savannah woodlands of the Riversleigh World Heritage Area, Queensland (approx. 24–15 Ma) and savannah grasslands of Hamilton, Victoria (approx. 4 Ma). This palaeoecological record has led to the proposal overviewed here to construct a lowland breeding facility with the goal of monitoring the outcome of introducing this possum back into the pre-Quaternary core habitat for the lineage. If this project succeeds, similar approaches could be considered for other climate-change-threatened Australian species such as the southern corroboree frog ( Pseudophryne corroboree ) and the western swamp tortoise ( Pseudemydura umbrina ). This article is part of a discussion meeting issue ‘The past is a foreign country: how much can the fossil record actually inform conservation?’

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:
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:
THE pre Holocene-Late Pleistocene record of Phascolarctos in Australia is extremely meagre. There are at least two, possibly three extinct species of Phascolarctos in addition to the extant Phascolarctos cinereus (Black 1999). P. yorkensis (syn. Cundokoala yorkensis; Black and Archer 1997) is known from the Early Pliocene Curramulka Local Fauna, South Australia (SA), and the Late Pleistocene Wellington Caves Local Fauna, New South Wales (Archer et al. 1997; Pledge 1992). P. stirtoni occurs in the Late Pleistocene Cement Mills Local Fauna, Queensland, and is known only from a partial maxilla containing P3-M2 (Bartholomai 1968, 1977). Phascolarctos material from the mid- Pleistocene Victoria Fossil Cave and Spring Cave, Naracoorte, SA, have also been referred to P. cf. stirtoni but remain undescribed (Reed and Bourne 2000; Moriarty et al. 2000). P. maris is known from a single lower molar from the Early Pliocene Sunlands Local Fauna, SA (Pledge 1987). Black (1999) cast doubt on its validity, suggesting its features may fall within the intraspecific variation of P. stirtoni. If P. maris is referable to P. stirtoni it is another South Australian instance of this species, and extends its range back to the Early Pliocene. The new phascolarctid material documented here is from the early Pleistocene Nelson Bay Local Fauna, Portland, Victoria (141o 35? E; 38o 36? S). It is therefore an important additional southern occurrence of a species larger than the living P. cinereus, and is the only pre- Late Pleistocene record of the Phascolarctidae in Victoria.

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:
The fossil record of marsupial lions (family Thylacoleonidae) from Australian Oligo Miocene deposits is generally poor. Study of new material of this family collected from Oligo-Miocene limestone sediments of the Riversleigh World Heritage Area, northwestern Queensland adds significant new information about previously described species and also indicates a greater diversity of thylacoleonids during this period of geological time. Two new genera and five new species are described. Reassessment of the holotype of the type species of Priscileo, P. pitikantensis,indicates it shows stronger affinities to species of the genus Wakaleo than it does to Priscileo roskellyae. Priscileo is regarded here to be a junior synonym of Wakaleo. The cranium and lower dentition of Priscileo roskellyae show significant morphological differences from species of Wakaleo, and this species is referred to a new genus, Lekaneleo. Distinctive morphological differences are identified in the M3s of Wakaleo oldfieldi and W. vanderleueri, species previously distinguished only by relative size differences in their dentitions. Functional morphological assessment of postcranial remains of species of Wakaleo suggests that they were probably scansorial or arboreal, but does not support a previous hypothesis of a fossorial habit. Cladistic analyses of the interrelationships of marsupial lions support the referral of Priscileo pitikantensis to the genus Wakaleo. The monotypic genus Microleo is the sister-group to all remaining thylacoleonid taxa. Species of Lekaneleo are the sistergroup to a Wakaleo/Thylacoleo clade. Intraordinal relationships of thylacoleonids were also investigated. Phylogenetic analyses of the interrelationships of Diprotodontia that included representatives of all extinct vombatiform families as well as extant taxa were conducted employing cranial and dental morphological characters. These analyses provide support for the hypothesis that Thylacoleonidae are members of the suborder Vombatiformes. Two species of Wakaleo (W. oldfieldi and W. vanderleueri) present in Riversleigh deposits are also found at other localities - respectively, the Leaf Locality of central Australia (Kutjamarpu LF) and the Small Hills Locality of northern Australia (Bullock Creek LF) - and suggest age estimations of the relevant Riversleigh sites of early Miocene and late Miocene. The phyletic evolution of Wakaleo suggests that some Riversleigh deposits are probably late Oligocene in age.
