Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

The Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Historical birth records from 1896 to 1944 from the Basel maternity hospital, Switzerland, reveal significant obstetric selection pressures

The Anatomical Record, EarlyView.
Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

The pelvis doesn't walk by itself: Wider pelves reduce the cost of walking over unstable surfaces

The Anatomical Record, EarlyView.
Abstract Walking over variable and/or unstable terrain is a key aspect of daily life and was crucial to the evolution of bipedalism. The ability to find gait solutions that maintained stability over uneven terrain for the least increase in metabolic cost was likely a hallmark of locomotor effectiveness in early humans, in particular acting as an ...

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis

The Anatomical Record, EarlyView.
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Osteology of the pectoral girdle and forelimb of Siriusgnathus niemeyerorum, a Late Triassic traversodontid cynodont from Brazil

The Anatomical Record, EarlyView.
Abstract Traversodontids are non‐mammaliaform cynodonts, herbivorous to omnivorous, that lived during the Triassic. In the Late Triassic, some members of this group increased in body size relative to other cynodont lineages and evolved postcranial adaptations associated with locomotion.
