Animals have evolved remarkable biomechanical and physiological systems that enable
their rich repertoire of motion. Animal Locomotion offers a fundamental understanding of …

Uncertainties in the phylogeny of birds (Avialae) and their closest relatives have impeded
deeper understanding of early theropod flight. To help address this, we produced an …

The Early Cretaceous Jehol Biota is a terrestrial lagerstätte that contains exceptionally well-
