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

open access: yesPapers 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.

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

open access: yesThe 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 ...

The osteology of Shuvosaurus inexpectatus, a shuvosaurid pseudosuchian from the Upper Triassic Post Quarry, Dockum Group of Texas, USA

open access: yesThe Anatomical Record, Volume 307, Issue 4, Page 1175-1238, April 2024.
Abstract A vast array of pseudosuchian body plans evolved during the diversification of the group in the Triassic Period, but few can compare to the toothless, long‐necked, and bipedal shuvosaurids. Members of this clade possess theropod‐like character states mapped on top of more plesiomorphic pseudosuchian character states, complicating our ...

A PRELIMINARY REVIEW OF THE BIOSTRATIGRAPHY OF THE UPPERMOST PERMIAN, TRIASSIC AND LOWERMOST JURASSIC OF GONDWANALAND [PDF]

open access: yes, 1970
This review pager was born out of a desire to visualize in some detail the picture of the evolving Gondwana Triassic landscape and the story of life and ecology upon it; a desire to provide a general setting in which to view the details of the work ...

Biodiversity, Cretaceous-Palaeogene crisis survival and phylogeny of Metasuchia (Crocodyliformes, Pseudosuchia)

open access: yes, 2023
The Metasuchia appeared during the Jurassic. At the Cretaceous, its diversity included semi-aquatic (e.g. Eusuchia) as well as marine (Tethysuchia) and terrestrial (Notosuchia) organisms. During its evolutionary history, it crossed two major crisis event, the OAE2 and the K/Pg boundary.
