The histology of rhynchosaur (Diapsida, Archosauromorpha) ankylothecodonty. [PDF]
J AnatAbstract The study of the connection between the teeth and the jaw is important for understanding the palaeobiology of vertebrates, but inconsistent terminology and incomplete sampling have made it difficult to assess the evolutionary significance of some of the related characters. Among archosauromorphs, tooth attachment in dinosaurs

The Inference of the Evolution of Immune Traits as Constrained by Phylogeny: Insight into the Immune System of the Basal Diapsid [PDF]
Animals, 2022 Among vertebrates, some of the most vulnerable taxa to emergent fungal pathogens are members of Reptilia. In light of the growing threat of emergent fungal pathogens affecting wildlife, it is important to broaden the current understanding of immune ...

Growth patterns and life-history strategies in Placodontia (Diapsida: Sauropterygia) [PDF]
Royal Society Open Science, 2015 Placodontia is a clade of durophagous, near shore marine reptiles from Triassic sediments of modern-day Europe, Middle East and China. Although much is known about their primary anatomy and palaeoecology, relatively little has been published regarding ...

Susceptibility of Gecko Cell Line for Cultivation and Adaptation of Infectious Bursal Disease Virus as an Experimental Vaccine. [PDF]
Vet Med SciFirst successful cultivation of IBDV on reptile‐derived Z1 cells yields high‐titre virus and induces immunity in chickens. This scalable, egg‐free platform offers a promising alternative for vaccine production, leveraging evolutionary kinship between reptiles and birds for next‐generation poultry disease control.

Systematics of putative euparkeriids (Diapsida: Archosauriformes) from the Triassic of China [PDF]
PeerJ, 2014 The South African species Euparkeria capensis is of great importance for understanding the early radiation of archosauromorphs (including archosaurs) following the Permo–Triassic mass extinction, as most phylogenetic analyses place it as the sister taxon

Trifold origin of the reptilian ear ossicle and its relation to the evolutionary modification of the temporal skull region. [PDF]
J AnatThe columella‐complex in reptile middle ears involves the footplate, columella shaft, and extracolumella. The latter is partly of quadrate developmental origin, whereas the footplate derives from the mesodermal otic capsule, the shaft and another part of the extracolumella from the hyoid arch.
