Bipedalism or bipedalisms: The os coxae of StW 573

Journal of Anatomy, EarlyView.
There has been a long debate about the possibility of multiple contemporaneous species of Australopithecus in both eastern and southern Africa, potentially exhibiting different forms of bipedal locomotion. Here, we describe the previously unreported morphology of the os coxae in the 3.67 Ma Australopithecus prometheus StW 573 from Sterkfontein Member 2

The hearing capabilities of the Dromornithidae (Aves), with inferences on acoustic communication and ecology

Journal of Anatomy, EarlyView.
The preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in

Quadrate orientation and joint reaction force underwent correlated evolution during suchian evolution

Journal of Anatomy, EarlyView.
The quadrate is the cranial bone of the nonmammalian jaw joint. The quadrate has long been hypothesized to mirror the direction of joint reaction forces (JRF) during feeding. This study uses 3D biomechanical modeling to reveal a striking evolutionary link between quadrate orientation and JRF direction, unlocking new insights into the dynamic forces ...

The origin and evolution of air sacs in pterosaurs and their forerunners

Journal of Anatomy, EarlyView.
Pneumatized pterosauromorph vertebrae and their phylogenetic context. Abstract Although the existence of postcranial pneumaticity and the inferred presence of air sacs connected to the lungs are well established in Pterosauria, the origin of this system in pterosaurs remains unclear. We investigated skeletal pneumaticity in the Triassic pterosauromorph

A suture in time: The ontogeny of cranial suture morphology in mammals

Journal of Anatomy, EarlyView.
Mammal cranial sutures are important indicators of the biomechanical and developmental pressures acting upon the skull. Across three prominent sutures dividing the vault of the mammalian skull, divergent patterns emerge both taxonomically and developmentally.
