The postcranial anatomy and osteohistology of Terrestrisuchus gracilis (Archosauria, Crocodylomorpha) from the Late Triassic of Wales

Papers in Palaeontology, Volume 10, Issue 4, July/August 2024.
Abstract The earliest crocodylomorphs, known as non‐crocodyliform crocodylomorphs, first appeared during the Late Triassic. In contrast to extant crocodylians, which are all semi‐aquatic, early crocodylomorphs represent terrestrial taxa with a fully erect posture and in most cases a small body size.

I believe I can fly… New implications for the mode of life and palaeoecology of the Late Triassic Ozimek volans based on its unique long bone histology

Palaeontology, Volume 67, Issue 3, May/June 2024.
Abstract The small diapsid reptile Ozimek volans is one of the most enigmatic representatives of the Late Triassic fauna of Krasiejów, Poland. Phylogenetically, Ozimek was identified as a ‘protorosaurian’ related to tanystropheids, but the extremely elongated limbs and presumed gliding abilities are unusual for this group.

Braincase and neuroanatomy of the lagerpetid Dromomeron gregorii (Archosauria, Pterosauromorpha) with comments on the early evolution of the braincase and associated soft tissues in Avemetatarsalia

The Anatomical Record, Volume 307, Issue 4, Page 1147-1174, April 2024.
Abstract The anatomy of the braincase and associated soft tissues of the lagerpetid Dromomeron gregorii (Archosauria: Avemetatarsalia) from the Late Triassic of the United States is here described. This corresponds to the first detailed description of cranial materials of Lagerpetidae, an enigmatic group of Late Triassic (c.

The osteology of the Late Triassic reptile Scleromochlus taylori from μCT data

The Anatomical Record, Volume 307, Issue 4, Page 1113-1146, April 2024.
Abstract Scleromochlus taylori is one of the most enigmatic members of the herpetofauna from the Lossiemouth Sandstone Formation (Upper Triassic) of Elgin (Moray, Scotland). For many years it was thought to be closely related to pterosaurs and dinosaurs, but the anatomy of this animal is difficult to interpret because of the notoriously poor ...

Evolution of the temporal skull openings in land vertebrates: A hypothetical framework on the basis of biomechanics

The Anatomical Record, Volume 307, Issue 4, Page 1559-1593, April 2024.
Abstract The complex constructions of land vertebrate skulls have inspired a number of functional analyses. In the present study, we provide a basic view on skull biomechanics and offer a framework for more general observations using advanced modeling approaches in the future.

Statistical analysis of skulls of Triassic proterosuchids (Reptilia, Archosauromorpha) from South Africa [PDF]

, 1993
Size-related differences have previously been considered to be important in distinguishing the four proterosuchian archosauromorph species described from South Africa. Previous authors hypothesized that these differences were due to allometric growth. In

A redescription of Trachelosaurus fischeri from the Buntsandstein (Middle Triassic) of Bernburg, Germany: the first European Dinocephalosaurus-like marine reptile and its systematic implications for long-necked early archosauromorphs

Swiss Journal of Palaeontology
Some of the earliest members of the archosaur-lineage (i.e., non-archosauriform archosauromorphs) are characterised by an extremely elongated neck. Recent fossil discoveries from the Guanling Formation (Middle Triassic) of southern China have revealed a ...
