A new phylogenetic hypothesis of Tanystropheidae (Diapsida, Archosauromorpha) and other “protorosaurs”, and its implications for the early evolution of stem archosaurs [PDF]
PeerJ, 2021 The historical clade “Protorosauria” represents an important group of archosauromorph reptiles that had a wide geographic distribution between the Late Permian and Late Triassic.

The cranial morphology of Tanystropheus hydroides (Tanystropheidae, Archosauromorpha) as revealed by synchrotron microtomography [PDF]
PeerJ, 2020 The postcranial morphology of the extremely long-necked Tanystropheus hydroides is well-known, but observations of skull morphology were previously limited due to compression of the known specimens.

Extreme neck elongation evolved despite strong developmental constraints in bizarre Triassic reptiles—implications for neck modularity in archosaurs [PDF]
Royal Society Open ScienceThe Triassic radiation of vertebrates saw the emergence of the modern vertebrate groups, as well as numerous extinct animals exhibiting conspicuous, unique anatomical characteristics.

The evolution of the manus of early theropod dinosaurs is characterized by high inter- and intraspecific variation. [PDF]
J Anat, 2018 Abstract The origin of the avian hand, with its reduced and fused carpals and digits, from the five‐fingered hands and complex wrists of early dinosaurs represents one of the major transformations of manus morphology among tetrapods. Much attention has been directed to the later part of this transition, from four‐ to three‐fingered taxa.

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

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 ...

Rivista Italiana di Paleontologia e Stratigrafia, 2000 The first diagnostic remains of the large prolacertiform Tanystropheus are reported from northeastern Italy. They include a proximal caudal vertebra from the Middle Triassic of Aupa valley (Udine, Friuli) and a cervical vertebra from the Carnian of Fusea

EVIDENCES FOR A SEMI AQUATIC LIFE STYLE IN THE TRIASSIC DIAPSID REPTILE TANYSTROPHEUS
Rivista Italiana di Paleontologia e Stratigrafia, 2018 The paleoecology of the bizarre, long-necked tanystropheid diapsid Tanystropheus from the Middle and Late Triassic of Western and Eastern Tethys has been debated since the first discoveries.
