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.

EVIDENCES FOR A SEMI AQUATIC LIFE STYLE IN THE TRIASSIC DIAPSID REPTILE TANYSTROPHEUS [PDF]
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.

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.

Synopsis of the Triassic reptiles from Germany [PDF]
Fossil RecordTriassic strata in the portion of the Central European Basin (CEB) that cover parts of conterminous Germany have yielded a long if discontinuous record of continental tetrapods spanning this period.

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.

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

Review of the tetrapod skull-neck boundary: implications for the evolution of the atlas-axis complex. [PDF]
Biol Rev Camb Philos SocABSTRACT This review describes variation in modern and fossil occiput–atlas–axis complex anatomy of total group Tetrapoda with the aim of documenting the range of structural variation throughout their evolutionary history to establish grounds for comparison of the complex between tetrapod clades.

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.
