The pseudosuchian record in paleohistology: A small review. [PDF]
Anat Rec (Hoboken)Abstract Archosauria originated around the Earth's largest biotic crisis that severely affected all ecosystems globally, the Permotriassic Mass extinction event, and comprises two crown‐group lineages: the bird‐lineage and the crocodylian lineage. The bird lineage includes the iconic pterosaurs, as well as dinosaurs and birds, whereas the crocodylian ...

The phylogenetic relationships of basal archosauromorphs, with an emphasis on the systematics of proterosuchian archosauriforms [PDF]
PeerJ, 2016 The early evolution of archosauromorphs during the Permo-Triassic constitutes an excellent empirical case study to shed light on evolutionary radiations in deep time and the timing and processes of recovery of terrestrial faunas after a mass extinction ...

Diversity of diapsid fifth metatarsals from the Lower Triassic karst deposits of Czatkowice, southern Poland—functional and phylogenetic implications [PDF]
Acta Palaeontologica Polonica, 2018 Three morphotypes of the fifth metatarsal (MttV), one of the most informative bones of the postcranium, have been described herein from the Early Triassic karst deposits of the Czatkowice locality (Southern Poland).

Soft tissues influence nasal airflow in diapsids: Implications for dinosaurs
Journal of Morphology, Volume 284, Issue 9, September 2023., 2023 Bony‐bounded airway of the theropod, Majungasaurus, showing multiple regions of the nasal passage where comparative CFD studies can reliably infear soft‐tissue locations. Abstract The nasal passage performs multiple functions in amniotes, including olfaction and thermoregulation.

Early archosauromorph remains from the Permo-Triassic Buena Vista Formation of north-eastern Uruguay [PDF]
PeerJ, 2015 The Permo-Triassic archosauromorph record is crucial to understand the impact of the Permo-Triassic mass extinction on the early evolution of the group and its subsequent dominance in Mesozoic terrestrial ecosystems.

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 occurrence of the Late Triassic archosaur Smok in southern Poland [PDF]
Acta Palaeontologica Polonica, 2018 Two isolated teeth, a dorsal vertebra, fragments of a humerus and femur, a fragmentary pubic “boot” and part of an ischium shaft, identified here as belonging to a large predatory archosaur were discovered in the Upper Triassic site at Marciszów near ...

Almost billfish: convergent longirostry, micro-dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy. [PDF]
J AnatA fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.
