Waving Through Ontogeny: The Larval Chondrocranial Development of Staurois parvus
International Journal of Zoology, Volume 2026, Issue 1, 2026.The vertebrate skull is a complex structure with diverse evolutionary and developmental patterns. Anuran chondrocranial development has been shown to deviate from generalized vertebrate trends, highlighting its evolutionary flexibility. This study investigates the chondrocranial development of Staurois parvus, a ranid frog, to provide insights into ...

Putative avian teeth from the Late Cretaceous of Alberta, Canada, are more likely from crocodilians.
PLoS ONE, 2023 Isolated teeth, previously referred to Aves, are more common than other bird fossils from the Late Cretaceous of Alberta. However, there are no known morphological synapomorphies that distinguish isolated bird teeth, and features of these teeth are ...

Review of the tetrapod skull–neck boundary: implications for the evolution of the atlas–axis complex
Biological Reviews, Volume 100, Issue 6, Page 2435-2470, December 2025.ABSTRACT This review describes variation in modern and fossil occiput–atlas–axis complex anatomy of total group Tetrapoda with the aim of documenting the range of structural variation throughout their evolutionary history to establish grounds for comparison of the complex between tetrapod clades.

Effects of Incubation and Rearing Temperatures on Caiman latirostris Growth [PDF]
, 2010 Different studies found that incubation temperature has an influence on the size of Caiman latirostris hatchlings and determines their gonadal sex. Experimental manipulations revealed that the effects of temperature on growth are independent of sex ...

Giant extinct caiman breaks constraint on the axial skeleton of extant crocodylians
eLife, 2019 The number of precaudal vertebrae in all extant crocodylians is remarkably conservative, with nine cervicals, 15 dorsals and two sacrals, a pattern present also in their closest extinct relatives.

Clutch size of Caiman latirostris (Crocodylia: Alligatoridae) varies on a latitudinal gradient [PDF]
, 2009 The distribution of the Broad-Snouted Caiman (Caiman latirostris) ranges from 5°S to 32°S. Thus, caiman populations are exposed to different climatic conditions, and this latitudinal gradient could affect aspects of their reproduction.
