Amphibians and Reptiles Exhibit Different Ecological and Evolutionary Spatial Patterns in the Amazon Basin. [PDF]
Ecol EvolThis study investigates the spatial variability of ecological and evolutionary patterns in amphibian and reptile lineages within the Amazon Basin. Our findings highlight distinct diversity patterns across lineages and ecoregions. ABSTRACT Understanding spatial variability in ecological and evolutionary patterns is key to Amazonian biodiversity ...

Clustering crocodylian dental morphology: Insights into functional adaptations, diet, and ontogeny. [PDF]
J AnatExtant crocodylians may be divided into five clusters based on the residuals of four linear dental measurements (y‐axes) and their variation along the jaw (x‐axes). These clusters correlate to snout shape, prey preference, and feeding ecology, particularly prey size and the degree of processing necessary. Multiple families and subfamilies were found in

Selection and trans-species polymorphism of major histocompatibility complex class II genes in the order Crocodylia. [PDF]
PLoS ONE, 2014 Major Histocompatibility Complex (MHC) class II genes encode for molecules that aid in the presentation of antigens to helper T cells. MHC characterisation within and between major vertebrate taxa has shed light on the evolutionary mechanisms shaping the

Embryological development of Caiman latirostris (Crocodylia: Alligatoridae) [PDF]
genesis, 2008 AbstractA standard development embryological series is the primary basis to organize information of any embryological study and is also used to determine the age of eggs and embryos in field conditions. In this article, we calibrate developmental series of the broad‐snouted caiman, Caiman latirostris, against an established series for Alligator ...

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 ...

Skull Anatomy of the Bizarre Crocodylian Mourasuchus nativus (Alligatoridae, Caimaninae) [PDF]
The Anatomical Record, 2012 AbstractMourasuchus is a Miocene alligatorid endemic to South America, and is represented by four species. Together with the closely related Purussaurus, it is a peculiar crocodylian taxon of neogene Caimaninae and one of the most bizarre forms among eusuchian crocodiles. The phylogenetic relationships between Mourasuchus species have not been explored,
