Arthrological reconstructions of the pterosaur neck and their implications for the cervical position at rest [PDF]

PeerJ
The lack of any pterosaur living descendants creates gaps in the knowledge of the biology of this group, including its cervical biomechanics, which makes it difficult to understand their posture and life habits.

A comprehensive embryonic staging series of the turtle Trachemys scripta

Developmental Dynamics, Volume 255, Issue 3, Page 260-320, March 2026.
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

The history, systematics, and nomenclature of Thalattosuchia (Archosauria: Crocodylomorpha)

Zoological Journal of the Linnean Society
Abstract The use of more than one nomenclatural code is becoming increasingly common in some biological sub-disciplines. To minimize nomenclatural instability, we have decided to establish a higher level systematization for Thalattosuchia under both the International Code of Phylogenetic Nomenclature (‘PhyloCode’) and the International ...

Flesh and bone: The musculature and cervical movements of pterosaurs [PDF]

Anais da Academia Brasileira de Ciências
The osteological variations present in the cervical vertebrae of pterosaurs represent changes in the soft tissues of the neck and reflect their function. Here, we infer the presence, volume, and capacity of the cervical musculature of pterosaurs.

Histology‐Based Morphology of the Neurocentral Synchondrosis in Alligator Mississippiensis (Archosauria, Crocodylia) [PDF]

The Anatomical Record, 2011
AbstractMorphology of the neurocentral synchondroses—thin cartilaginous layers between centra and neural arches—are documented in the extant crocodilian, Alligator mississippiensis (Archosauria, Crocodylia). Examination of dry skeletons demonstrates that neurocentral suture closure occurs in very late postnatal ontogeny (after reaching sexual maturity ...

Osteohistology of the silesaurid Sacisaurus agudoensis from southern Brazil (Late Triassic) and implications for growth in early dinosaurs

Anais da Academia Brasileira de Ciências
: The non-dinosaurian dinosauriform silesaurids are the closest relatives of crown-group dinosaurs and are thus, important for understanding the origins of that group.

A new species of the Late Triassic aetosaur Desmatosuchus (Archosauria: Pseudosuchia)

Comptes Rendus Palevol, 2005
Reanalysis of known armor of the stagonolepidid (aetosaur) Desmatosuchus has shown distinct differences in the lateral armor among individuals known from Carnian and Norian age rocks in the southwestern United States. Combined with previously reported cranial differences it is apparent that Norian specimens of Desmatosuchus represent a species distinct
