The holotype of the basal archosauromorph Prolacerta broomi revisited [PDF]
Acta Palaeontologica Polonica, 2023 Prolacerta broomi is one of the most important of fossil reptiles. First considered as one of the earliest members of squamates, this basal archosauromorph has been used as a model for diapsid morphological evolution ever since its discovery, playing ...

Colobops: a juvenile rhynchocephalian reptile (Lepidosauromorpha), not a diminutive archosauromorph with an unusually strong bite [PDF]
Royal Society Open Science, 2020 Correctly identifying taxa at the root of major clades or the oldest clade-representatives is critical for meaningful interpretations of evolution. A small, partially crushed skull from the Late Triassic (Norian) of Connecticut, USA, originally described

The evolution of muscle spindles. [PDF]
Exp PhysiolAbstract Muscle spindles are stretch‐sensitive mechanoreceptors found in the skeletal muscles of most four‐limbed vertebrates. They are unique amongst sensory receptors in the ability to regulate their sensitivity by contraction of the intrafusal muscle fibres on which the sensory endings lie.

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 enigmatic marine reptile nanchangosaurus from the lower triassic of Hubei, China and the phylogenetic affinities of Hupehsuchia. [PDF]
PLoS ONE, 2014 The study of the holotype and of a new specimen of Nanchangosaurus suni (Reptilia; Diapsida; Hupehsuchia) revealed a suite of hitherto unrecognized characters.

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 ...

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.

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.

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

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).
