Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

A 115,000-year-old expedient bone technology at Lingjing, Henan, China.

open access: yesPLoS ONE, 2021
Activities attested since at least 2.6 Myr, such as stone knapping, marrow extraction, and woodworking may have allowed early hominins to recognize the technological potential of discarded skeletal remains and equipped them with a transferable skillset ...

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

open access: yesThe Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II

open access: yesThe Anatomical Record, EarlyView.
Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.

Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

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

open access: yesThe 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.
