Abstract:
Comparative morphological studies can provide insights into an animal’s ecology and evolutionary history. Functional morphological studies of the kangaroo forelimb are few in number and new work could provide novel tools to aid in the interpretation of fossil taxa and the understanding of the evolutionary history of kangaroos and marsupials as a whole. A description of the shoulder and forelimb musculature of the tammar wallaby (Macropus eugenii) with comparisons to the red kangaroo (Macropus rufus Desmarest, 1842), the western grey kangaroo (Macropus fuliginosus Desmarest, 1817) and the quokka (Setonix brachyurus Quoy & Gaimard, 1830) is presented. The species chosen were readily available and represent a range in size of the archetypal kangaroo form. Muscle maps of forelimb and shoulder muscles were constructed as an aid to comparing the spatial arrangement of muscle origins and insertions. The anatomical pattern of forelimb musculature in terrestrial macropodine kangaroos and wallabies is highly conservative. Functionally, the musculature of the forelimb corresponds to a supporting role of the limb during slow pentapedal locomotion. The illustrations of muscle insertions provided in this work will be a useful reference for future work in comparative marsupial anatomy and palaeobiology.

Full text
Abstract:
This study presents a natural disarticulation sequence for the western grey kangaroo, Macropus fuliginosus, from surface bone assemblages in semi-arid South Australia. Comparison with published disarticulation sequences for African ungulates reveals significant differences in the kangaroo sequence, including earlier disarticulation of the forelimb long bones, carpus and cervical elements, and later disarticulation of the caudal vertebrae, and hindlimb long bones. These differences closely correspond to anatomical and morphological features of the kangaroo skeleton. The results of this study suggest that anatomy plays an important role in disarticulation and may ultimately control the process even following utilisation by predators and scavengers. The disarticulation sequence reported here has useful applications for the interpretation of fossil bone assemblages containing both extant and extinct kangaroos.

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:
A method, based on femoral circumference, allowed us to develop body mass estimates for 11 extinct Pleistocene megafaunal species of macropodids (Protemnodon anak, P. brehus, P. hopei, P. roechus, Procoptodon goliah, ‘P.’ gilli, Simosthenurus maddocki, S. occidentalis, Sthenurus andersoni, S. stirlingi and S. tindalei) and three fossil populations of the extant eastern grey kangaroo (Macropus giganteus). With the possible exception of P. goliah, the extinct taxa were browsers, among which sympatric, congeneric species sort into size classes separated by body mass increments of 20–75%. None show evidence of size variation through time, and only the smallest (‘P.’ gilli) exhibits evidence suggestive of marked sexual dimorphism. The largest surviving macropodids (five species of Macropus) are grazers which, although sympatric, do not differ greatly in body mass today, but at least one species (M. giganteus) fluctuated markedly in body size over the course of the Pleistocene. Sexual dimorphism in these species is marked, and may have varied through time. There is some mass overlap between the extinct and surviving macropodid taxa. With a mean estimated body mass of 232 kg, Procoptodon goliah was the largest hopping mammal ever to exist.

Abstract:
Historical concepts of the generic status of the macropodines commonly known as kangaroos and wallabies are reviewed in this paper. A new diagnosis is provided for the genus Macropus, encompassing both living and fossil forms, and using cladistic principles to assess the phylogenetic value of diagnostic characters where possible. Cytological, biochemical and anatomical characters are used. Fourteen living and 11 extinct species of Macropus are recognized. Of these, 20 species have been classified into three subgenera, M.(Macropus), M.(Osphranter) and a new subgenus, M.(Notamacropus), as follows: M.(M.) giganteus, M.(M.) fuliginosus, M.(M.) mundjabus, M.(M.) pan, M.(M.) pearsoni and M.(M.) ferragus; M.(O.) antilopinus, M.(O.) bernardus, M.(O.) robustus, M.(O.) rufus and M.(O.) pavana; ,M.(N.) rufogriseus, M.(N.) eugenii, M.(N.) parryi, M.(N.) dorsalis, M.(N.) irma, M.(N.) agilis, M.(N.) greyi, M.(N.) parma, M.(N.) wombeyensis and M.(N) thor. Four poorly known extinct species, M. dryas, M. rama, M. woodsi and M. narada, have not yet been allocated to a subgenus. Prionotemnus palankarinnicus Stirton, 1957 is shown to belong outside Macropus. Because it is the type-species of Prionotemnus, that name is not available for a subgenus of Macropus. A current synonymy is presented for fossil species and the known stratigraphic range is given for each species. A phylogeny is presented expressing our view that M. (,Votamacropus) is the most plesiomorphic subgenus and M. (Macropus) is the most derived.

Abstract:
Dental microwear texture analysis (DMTA) quantifies microscopic scar or wear patterns left on teeth by different foods or extraneous ingested items such as grit. It can be a powerful tool for deducing the diets of extinct mammals. Here we investigate how intraspecific variation in the dental microwear of macropodids (kangaroos and their close relatives) can be used to maximize the dietary signal inferable from an inherently limited fossil record. We demonstrate significant intraspecific variation for every factor considered here for both scale-sensitive fractal analysis and International Organization for Standardization surface texture analysis variables. Intraspecific factors were then incorporated into interspecific (dietary) analyses through the use of Linear Mixed Effects modelling, incorporating Akaike's Information Criterion to compare models, and testing models through independent cross-validation. This revealed that for each DMTA variable only a small number of intraspecific factors need to be included to improve differentiation between species. Including specimen as a random factor accounted for stochastic inter-individual variation, and facet , incorporated effects of sampling location. Intraspecific effects of ecoregion, microscope, tooth position and wear were often but not universally important. We conclude that models of microwear data that include intraspecific variation can improve the resolution of dietary reconstructions.

Abstract:
AbstractThroughout the late Quaternary, the Sahul (Pleistocene Australia–New Guinea) vertebrate fauna was dominated by a diversity of large mammals, birds, and reptiles, commonly referred to as megafauna. Since ca. 450–400Ka, approximately 88 species disappeared in Sahul, including kangaroos exceeding 200kg in size, wombat-like animals the size of hippopotamuses, flightless birds, and giant monitor lizards that were likely venomous. Ongoing debates over the primary cause of these extinctions have typically favored climate change or human activities. Improving our understanding of the population biology of extinct megafauna as more refined paleoenvironmental data sets become available will assist in identifying their potential vulnerabilities. Here, we apply a multiproxy approach to analyze fossil teeth from deposits dated to the middle and late Pleistocene at Cuddie Springs in southeastern Australia, assessing relative aridity via oxygen isotopes as well as vegetation and megafaunal diets using both carbon isotopes and dental microwear texture analyses. We report that the Cuddie Springs middle Pleistocene fauna was largely dominated by browsers, including consumers of C4 shrubs, but that by late Pleistocene times the C4 dietary component was markedly reduced. Our results suggest dietary restriction in more arid conditions. These dietary shifts are consistent with other independently derived isotopic data from eggshells and wombat teeth that also suggest a reduction in C4 vegetation after ~45 Ka in southeastern Australia, coincident with increasing aridification through the middle to late Pleistocene. Understanding the ecology of extinct species is important in clarifying the primary drivers of faunal extinction in Sahul. The results presented here highlight the potential impacts of aridification on marsupial megafauna. The trend to increasingly arid conditions through the middle to late Pleistocene (as identified in other paleoenvironmental records and now also observed, in part, in the Cuddie Springs sequence) may have stressed the most vulnerable animals, perhaps accelerating the decline of late Pleistocene megafauna in Australia.

Abstract:
Living kangaroos, wallabies and rat-kangaroos (Macropodoidea) constitute the most ecologically diverse radiation of Australasian marsupials. Indeed, even their hallmark bipedal hopping gait has been variously modified for bounding, walking and climbing. However, the origins of this locomotory adaptability are uncertain because skeletons of the most ancient macropodoids are exceptionally rare. Some of the stratigraphically oldest fossils have been attributed to Balbaridae—a clade of potentially quadrupedal stem macropodoids that became extinct during the late Miocene. Here we undertake the first assessment of balbarid locomotion using two-dimensional geometric morphometrics and a correlative multivariate analysis of linear measurements. We selected the astragalus and pedal digit IV ungual as proxies for primary gait because these elements are preserved in the only articulated balbarid skeleton, as well as some unusual early Miocene balbarid-like remains that resemble the bones of modern tree-kangaroos. Our results show that these fossils manifest character states indicative of contrasting locomotory capabilities. Furthermore, predictive modelling reveals similarities with extant macropodoids that employ either bipedal saltation and/or climbing. We interpret this as evidence for archetypal gait versatility, which probably integrated higher-speed hopping with slower-speed quadrupedal progression and varying degrees of scansoriality as independent specializations for life in forest and woodland settings.

Abstract:
Mandibular and postcranial remains attributable to a new fossil kangaroo (Macropodoidea) are described from the Oligocene-Miocene Etadunna Formation deposits of Ngama Quarry at Lake Palankarinna in north-eastern South Australia. The taxon is uniquely differentiated by its straight bunolophodont molar row, elongate P3 with distinct labial/lingual cingulids and 12–13 fine (shallowly incised) cuspids/transcristids, molars with a rectangular (length at least 0.3 > width) occlusal outline, hypolophid formed by a buccally directed crest from the entoconid, absence of a discrete M1 protostylid, transversely broad trigonid basin on the M1, M4 not markedly smaller than the anterior molars, distal end of humerus with sub-equally sized capitellum and trochlea (the latter also closely abutting the entepicondyle), and ulna with distinctly sinuous ventral edge. Relationships of the Ngama Quarry kangaroo are poorly resolved because of missing data; however, inclusion within the most comprehensive published phylogenetic dataset of Macropodoidea suggests close affinity with the currently extant potoroine/macropodid lineage.
