Silesaurid (Archosauria: Dinosauriformes) remains from the base of the Dockum Group (Late Triassic: Otischalkian) of Texas provide new insights to the North American record of dinosauriforms

open access: yesThe Anatomical Record, EarlyView.
Abstract Silesaurids (Archosauria: Dinosauriformes) are found in Middle to Upper Triassic deposits across Pangea, but few stratigraphic sections record the evolution of the group in one geographic area over millions of years. Here, we describe silesaurid remains from the oldest of the Upper Triassic stratigraphic sequence from the base of the Dockum ...

Development of the occipitopetrosal junctions: A histological study using human fetuses

open access: yesThe Anatomical Record, EarlyView.
Abstract The temporal bone petrosa is connected to the occipital bone at two sites: one junction with the basilar part (medial junction) and another with the lateral part (lateral junction). Using histological specimens from 45 human fetuses (approximately 7–39 weeks of gestational age or GA), we aimed to describe possible changes in histology and ...

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

open access: yesThe 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

Intraspecific variation of cochlear morphology in bowhead and beluga whales

open access: yesThe Anatomical Record, EarlyView.
Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...
