Adaptations for digging in the forelimb muscle anatomy of the southern brown bandicoot (Isoodon obesulus) and bilby (Macrotis lagotis)
Comparative and functional interpretations indicate that the forelimb of I. obesulus is well equipped for scratch digging and demonstrates muscular modifications in order to generate large out-forces via a reduced out-lever length. Expand
Evolution of the patella and patelloid in marsupial mammals
There is substantial homoplasy in marsupial patellae regardless of the evolutionary algorithm adopted, and novel evidence of an ossified patella in one specimen of Macropus rufogriseus, with hints of similar variation in other species. Expand
The remarkable vocal anatomy of the koala (Phascolarctos cinereus): insights into low‐frequency sound production in a marsupial species
This work uses advanced imaging techniques, histological data, classical macroscopic dissection and behavioural observations to provide the first detailed description and interpretation of male and female koala vocal anatomy, showing that both males and females have an elongated pharynx and soft palate, resulting in a permanently descended larynx.

Forelimb Myology of Carnivorous Marsupials (Marsupialia: Dasyuridae): Implications for the Ancestral Body Plan of the Australidelphia
In nearly all aspects of anatomy, it is found that the arrangement of the muscular origins and insertions, and the relative degree of separation between muscle bellies among dasyurids, provide a natural starting point from which the anatomies of other Australidelphian marsupial groups can be derived.

Musculoskeletal networks reveal topological disparity in mammalian neck evolution
The findings reveal that the limited number of vertebrae in the mammalian neck does not result in a low musculoskeletal disparity when examined in an evolutionary context, and this disparity evolved late in mammalian history in parallel with the radiation of certain lineages. Expand
Hind limb myology of the southern brown bandicoot (Isoodon obesulus) and greater bilby (Macrotis lagotis) (Marsupialia : Peramelemorphia)
Differences between the hind limb anatomy of I. obesulus and M. lagotis reflect the different ecological and environmental pressures on their locomotion and digging behaviours. Expand
Morphometric studies on the skull in three marsupial species (Koala, Wombat, Wallaby).
Three koala, two wombat and three Grey’s wallaby skulls were used in this traditional morphometric study and the usage of these morphometric measurements in several basic and clinical applications as well as in evaluating the intelligence status of these species. Expand
Comparative Triceps Surae Morphology in Primates: A Review
Data on the fiber type and muscle mass variation in the ankle plantar flexors of primates and comparisons to other mammals suggest that great apes, atelines, and lorisines exhibit similarity in the mass distribution of the triceps surae, and it is concluded that variation in tricepsSurae may be related to the shared locomotor mode exhibited by these groups. Expand
Functional morphology of the forelimb of living and extinct tree‐kangaroos (Marsupialia: Macropodidae)
The first detailed description of the functional anatomy of the forelimb, a central component of the locomotor complex, in the extant Dendrolagus lumholtzi is provided, and its structure and function is compared with representatives of other extant marsupial families. Expand
Forelimb musculature of kangaroos with particular emphasis on the tammar wallaby Macropus eugenii (Desmarest, 1817)
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 workExpand
