The Phylogeny and Palaeobiology of “Protorosauria” with a Focus on the Genus Tanystropheus

Journal of Vertebrate Paleontology, 2020
Summary “Protorosaurs” are a group of early archosauromorph reptiles (i.e. stem-archosaurs, the reptile clade containing modern birds and crocodylians). They are characterized by their long necks, which are comprised of elongate cervical vertebrae with low neural spines and long and thin cervical ribs.

Decapitation in the long-necked Triassic marine reptile Tanystropheus

Current Biology, 2023
Extreme neck elongation was a common evolutionary strategy among Mesozoic marine reptiles, occurring independently in several lineages1,2. Despite its evolutionary success, such an elongate neck might have been particularly susceptible to predation1, but direct evidence for this possibility has been lacking.

Osteology of a New Specimen of Macrocnemus aff. M. fuyuanensis (Archosauromorpha, Protorosauria) from the Middle Triassic of Europe: Potential Implications for Species Recognition and Paleogeography of Tanystropheid Protorosaurs

Frontiers in Earth Science, 2017
Over the past two decades, a wealth of marine and terrestrial reptiles, including protorosaurian archosauromorphs, has been described from Triassic shales and limestone layers in southern China.

The topological organization of the turtle cranium is constrained and conserved over long evolutionary timescales

The Anatomical Record, Volume 307, Issue 8, Page 2713-2748, August 2024.
Abstract The cranium of turtles (Testudines) is characterized by the secondary reduction of temporal fenestrae and loss of cranial joints (i.e., characteristics of anapsid, akinetic skulls). Evolution and ontogeny of the turtle cranium are associated with shape changes.

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.

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 ...

Bernhard Peyer and his discoveries of Triassic vertebrates in Switzerland

Swiss Journal of Palaeontology
Bernhard Peyer (1885–1963) was a prominent Swiss vertebrate palaeontologist and anatomist at the University of Zurich. In 1919, he discovered the occurrence of Middle Triassic (Anisian–Ladinian) ichthyosaurs, sauropterygians, and other reptiles at Monte ...
