The evolution of femoral osteology and soft tissues on the line to extant birds (Neornithes)
Femoral osteology and soft tissues evolved in a stepwise pattern in archosauromorph reptiles on the line to crown group birds. Crocodylia retains most ancestral archosaurian traits, whereasExpand

Pelvic and hindlimb musculature of Tyrannosaurus rex (Dinosauria: Theropoda)
In this article, we develop a new reconstruction of the pelvic and hindlimb muscles of the large theropod dinosaur Tyrannosaurus rex. Our new reconstruction relies primarily on direct examination ofExpand

The locomotor kinematics of Asian and African elephants: changes with speed and size
SUMMARY For centuries, elephant locomotion has been a contentious and confusing challenge for locomotion scientists to understand, not only because of technical difficulties but also because elephantExpand

The anatomy and functions of muscle-tendon complexes and their bony attachments in birds and their outgroups show how the major pelvic limb muscle groups evolved. Fossils reveal that most changesExpand

Trabecular bone scales allometrically in mammals and birds
Many bones are supported internally by a latticework of trabeculae. Scaling of whole bone length and diameter has been extensively investigated, but scaling of the trabecular network is not wellExpand

Analysis of hindlimb muscle moment arms in Tyrannosaurus rex using a three-dimensional musculoskeletal computer model: implications for stance, gait, and speed
Abstract Muscle moment arms are important determinants of muscle function; however, it is challenging to determine moment arms by inspecting bone specimens alone, as muscles have curvilinear pathsExpand

Biomechanics: Are fast-moving elephants really running?
We use video analysis to show that Asian elephants (Elephas maximus L.) can move at surprisingly high speeds of up to 6.8 m s−1 (25 km h−1) and that, although their gait might seem to be a walk even at this speed, some features of their locomotion conform to definitions of running. Expand

Functional specialisation of pelvic limb anatomy in horses (Equus caballus)
We provide quantitative anatomical data on the muscle–tendon units of the equine pelvic limb. Specifically, we recorded muscle mass, fascicle length, pennation angle, tendon mass and tendon restExpand

Adductors, abductors, and the evolution of archosaur locomotion
Abstract Living crocodilians (Crocodylia) and birds (Neornithes) differ in many aspects of hindlimb anatomy and locomotor function. How did this disparity evolve? We integrate information fromExpand
