Phylogenetic analysis of a new morphological dataset elucidates the evolutionary history of Crocodylia and resolves the long-standing gharial problem [PDF]
PeerJ, 2021 First appearing in the latest Cretaceous, Crocodylia is a clade of semi-aquatic, predatory reptiles, defined by the last common ancestor of extant alligators, caimans, crocodiles, and gharials.

The effects of cryptic diversity on diversification dynamics analyses in Crocodylia [PDF]
Proceedings of the Royal Society B: Biological SciencesIncomplete taxon sampling due to underestimation of present-day biodiversity biases diversification analysis by favouring slowdowns in speciation rates towards the recent time. For instance, in diversification dynamics studies in Crocodylia, long-term low net-diversification rates and slowdowns in speciation rates have been ...

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

Acta Herpetologica, 2021 Bone histology is an important tool for the interpretation of life patterns in animals of the past and extant fauna. The crocodylians have been studied as important inferential models for morphophysiological characteristics.

Evolution of MHC class I in the Order Crocodylia [PDF]
Immunogenetics, 2013 The major histocompatibility complex (MHC) is a dynamic genomic region with an essential role in the adaptive immunity of jawed vertebrates. The evolution of the MHC has been dominated by gene duplication and gene loss, commonly known as the birth-and-death process. Evolutionary studies of the MHC have mostly focused on model species.

A revision of the evolutionary relationships of Crocodylia [PDF]
, 2020 First appearing in the latest Cretaceous, Crocodylia is a clade of mostly semi-aquatic, predatory reptiles, defined as all of the descendants of the last common ancestor of the extant alligators, caimans, crocodiles, and gharials. Crocodylian phylogeny has been extensively studied using molecular and morphological datasets; however, numerous systematic

Cocodrilos (Archosauria: Crocodylia) de la región neotropical [PDF]
Biota Colombiana, 2000 Crocodylia [Gmelin, 1789], originalmente Crocodili, es un orden con distribución circuntropical, aunque algunas especies actualmente ocupan áreas cálidas de la zona temperada. Los cocodrilos vivientes tienen sus ancestros en los protosuchios del triásico

Structure and evolution of the embryonic cartilaginous skull of crocodilians [PDF]
Royal Society Open ScienceThe evolution of skull diversity in Crocodylia is rather well documented, but the developmental foundation of their cranial architecture remains poorly understood. Here, we present the first three-dimensional reconstruction of the embryonic cartilaginous
