The bipedal stance and gait of theropod dinosaurs evolved gradually along the lineage
leading to birds and at some point (s), flight evolved. How and when did these changes …

The intersection of paleontology and biomechanics can be reciprocally illuminating, helping
to improve paleobiological knowledge of extinct species and furthering our understanding of …

Paleobiological reconstructions of joint mobility are an essential component of functional
analyses of extinct animals. Over the past half-decade, the methods underlying mobility …

Studies of soft tissue effects on joint mobility in extant animals can help to constrain
hypotheses about joint mobility in extinct animals. However, joint mobility must be …

Extinct archosaurs, including many non-avian dinosaurs, exhibit relatively simply shaped
condylar regions in their appendicular bones, suggesting potentially large amounts of …

The last common ancestor of birds and crocodylians plus all of its descendants (clade
Archosauria) dominated terrestrial Mesozoic ecosystems, giving rise to disparate body …

Paleobiologists typically exclude impossible joint poses from reconstructions of extinct
animals by estimating the rotational range of motion (ROM) of fossil joints. However, this …

ABSTRACT A new species, Camptosaurus aphanoecetes, is named for a partial skeleton of
ornithopod dinosaur from the Morrison Formation (Upper Jurassic) of Dinosaur National …

Scientific literature and museum exhibits are full of explicit and implicit claims about the
possible postures and motion ranges of dinosaurs. For the example of the prosauropod …
