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 ...

Archosauromorpha Huene 1946

, 2018
Archosauromorpha Huene, 1946, sensu Benton, 1985 Gen. et sp. indet. Referred specimens. TTU-P 11254c, partial braincase; TTU-P 11254d, cervical vertebrae; TTU-P 11254e, left scapula. Description and remarks. The braincase is poorly preserved, and the intimately fused bones complicate the demarcation of each element.

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

The early evolution of rhynchosaurs

Frontiers in Ecology and Evolution, 2016
The rhynchosaurian archosauromorphs are an important and diverse group of fossil tetrapods that first appeared during the Early Triassic and probably became extinct during the early Late Triassic (early Norian).

An exquisitely preserved young iguanodontian from the Upper Jurassic of Tanzania sheds light on skeletal fusion patterns within Archosauria

Papers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Dysalotosaurus lettowvorbecki (Ornithopoda, Dinosauria) is a small‐sized dryosaurid iguanodontian known from various isolated remains collected from the Tendaguru Formation (Upper Jurassic, Tanzania). Micro‐computed tomography of a small individual encased in a block offered a unique opportunity to describe c.

Inferred presence of extraoral tissues in Triassic archosauromorphs and the evolutionary implications for the clade Sauropsida

Palaeontology, Volume 69, Issue 3, 2026.
Abstract Recent work has suggested that the presence of extraoral soft tissues (‘lips’), in the form of labial scales in theropod dinosaurs, could be inferred based on: anteroposteriorly distributed foramina in the rostral bones, similar to extant lepidosaurs; vertically projected teeth; uniform enamel thickness in maxillary teeth; and an allometric ...

Braincase anatomy and palaeoneurology of Venetoraptor gassenae, a lagerpetid pterosauromorph from the Late Triassic of southern Brazil

Palaeontology, Volume 69, Issue 2, 2026.
Abstract There is a growing consensus that pterosaurs and the flightless Lagerpetidae are closely related. This relationship is supported by apomorphies throughout the skeleton, including endocranial character states such as a well‐developed floccular fossa and a tall anterior semicircular canal. Our knowledge of lagerpetid anatomy has been improved by
