Experimental assessment of diffusible iodine-based contrast-enhanced computed tomography (diceCT) protocols Open
Diffusible iodine-based contrast-enhanced computed tomography (diceCT) is an increasingly used digital complement, supplement, or alternative to traditional dissection-based anatomical research. The diceCT protocol, which has evolved and e…

Traditional and digital examination of the baculum of a leopard seal (<i>Hydrurga leptonyx</i>) Open
While terrestrial breeding in polygynous species of pinnipeds allows for observations of reproductive behavior (Atkinson, 1997), similar opportunities are limited for cryptic, nonpolygynous, aquatic-breeding species. The isolated nature of…

Hanging on and digging deep: comparative forelimb myology of the koala (<i>Phascolarctos cinereus</i>) and common wombat (<i>Vombatus ursinus</i>) Open
Establishing relationships between soft tissues and bones in living species can inform our understanding of functional adaptations in their extinct kin in the absence of direct data on habitual behaviours. The koala and the wombats are the…

Sharp and fully loaded: 3D tissue reconstruction reveals how snake fangs stay deadly during fang replacement Open
Snake venom is produced, transported and delivered by the sophisticated venom delivery system (VDS). When snakes bite, the venom travels from the venom gland through the venom duct into needle‐like fangs that inject it into their prey. To …

Low elbow mobility indicates unique forelimb posture and function in a giant extinct marsupial Open
Joint mobility is a key factor in determining the functional capacity of tetrapod limbs, and is important in palaeobiological reconstructions of extinct animals. Recent advances have been made in quantifying osteological joint mobility usi…

The extraordinary osteology and functional morphology of the limbs in Palorchestidae, a family of strange extinct marsupial giants Open
The Palorchestidae are a family of marsupial megafauna occurring across the eastern Australian continent from the late Oligocene through to their extinction in the Late Pleistocene. The group is known for their odd 'tapir-like' crania and …

The development of curvature in the porcine radioulna Open
Long bone curvature in animal limbs has long been a subject of interest and much work has explored why long bones should be curved. However, the ‘when’ and ‘how’ of curvature development is poorly understood. It has been shown that the rat…

Forelimb bone curvature in terrestrial and arboreal mammals Open
It has recently been proposed that the caudal curvature (concave caudal side) observed in the radioulna of terrestrial quadrupeds is an adaptation to the habitual action of the triceps muscle which causes cranial bending strains (compressi…

Curvature reduces bending strains in the quokka femur Open
This study explores how curvature in the quokka femur may help to reduce bending strain during locomotion. The quokka is a small wallaby, but the curvature of the femur and the muscles active during stance phase are similar to most quadrup…
