Sharpening our understanding of saber‐tooth biomechanics

The Anatomical Record, EarlyView.
Abstract Saber‐teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber‐toothed taxa employed a distinct biting strategy compared to conical‐toothed carnivores, like the lion, the precise mechanics and variability of this ...

Commentary: The missing sabertooth baculum—At what point might the absence of evidence reasonably be considered evidence of absence?

The Anatomical Record, EarlyView.
Abstract Most carnivorans and all modern felids have ossified bacula; however, no machairodont baculum has ever been identified. This is true despite the many fairly complete skeletons found around the world of several sabertooth taxa. Although the bacula of modern felids are much smaller than those of canoids (even the least weasel's baculum is longer

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

China shares fossil treasures with the world

The Anatomical Record, EarlyView.
Abstract China has been a rich source of fossils for nearly a century, beginning with the discovery of so‐called Peking man (Sinanthropus pekinensis), known today as Homo erectus pekinensis in the mid 1920s. The first Chinese dinosaurs were described in 1929, the sauropod Helopus (now Euhelopus) and the ornithopod Tanius, described by the Swedish ...

The lower jaw of Devonian ray‐finned fishes (Actinopterygii): Anatomy, relationships, and functional morphology

The Anatomical Record, EarlyView.
Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian
