RAIBLIANIA CALLIGARISI GEN. N., SP. N., A NEW TANYSTROPHEID (DIAPSIDA, TANYSTROPHEIDAE) FROM THE UPPER TRIASSIC (CARNIAN) OF NORTHEASTERN ITALY

Rivista Italiana di Paleontologia e Stratigrafia, 2020
Tetrapod remains are extremely rare in the early Carnian (Late Triassic) Calcare del Predil Formation on the Italian side of the Julian Alps (Friuli Venezia Giulia Autonomous Region), which yielded the Raibl fossil assemblage including the famous "Raibl ...

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 [PDF]

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.

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 ...

A description of the palate and mandible of Youngina capensis (Sauropsida, Diapsida) based on synchrotron tomography, and the phylogenetic implications

Papers in Palaeontology, Volume 9, Issue 5, September/October 2023., 2023
Abstract The late Permian reptile Youngina capensis (c. 254 Ma) is a non‐saurian neodiapsid whose anatomy has been used to represent the reptilian condition prior to the divergence of Sauria (crown‐group reptiles). However, despite being first described over 100 years ago, the anatomy of Youngina remains incompletely documented. Here we use synchrotron

A new long‐necked archosauromorph from the Guanling Formation (Anisian, Middle Triassic) of southwestern China and its implications for neck evolution in tanystropheids

, 2023
A long neck is an evolutionary innovation convergently appearing in multiple tetrapod lineages, including groups of plesiosaurs, non-archosauriform archosauromorphs, turtles, sauropodomorphs, birds, and mammals.

Tanystropheids from the Winterswijk quarry - rare but recurring elements [PDF]

, 2019
Tanystropheids were archosauromorph reptiles from the Triassic characterized by long necks composed of elongate cervical vertebrae and ribs, as is epitomized by its most recognisable genus Tanystropheus. An isolated cervical vertebra from the Winterswijk

Micro‐CT informed cranial anatomy of the early rhynchosaur Howesia browni, with implications for rhynchosaur skull evolution

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Rhynchosaurs are unusual archosauromorph reptiles that lived between the Induan and early Norian (Early to early Late Triassic). They are characterized by their stocky build and broad skull with a beak‐like premaxilla. This rather charismatic configuration is most clearly expressed in Late Triassic hyperodapedontine rhynchosaurids.

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 ...
