Structure and evolution of the embryonic cartilaginous skull of crocodilians [PDF]

open access: yesRoyal Society Open Science
The 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

Bone histology of Broad-snouted Caiman Caiman latirostris (Crocodylia: Alligatoridae) as tool for morphophysiological inferences in Crocodylia

open access: yesActa 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.

Temperature variation in nests of Caiman crocodilus (Crocodylia: Alligatoridae)

open access: yesActa Herpetologica, 2007
Caiman crocodilus is a widely distributed species in the Neotropics; however, studies of incubation temperatures in wildlife are uncommon. Incubation temperature in four nests of Caiman crocodilus were measured with a digital thermometer, in the National

ReptTraits: a comprehensive dataset of ecological traits in reptiles [PDF]

open access: yesScientific Data
Trait datasets are increasingly being used in studies investigating eco-evolutionary theory and global conservation initiatives. Reptiles are emerging as a key group for studying these questions because their traits are crucial for understanding the ...

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia. [PDF]

open access: yesJ Anat
Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

Clustering crocodylian dental morphology: Insights into functional adaptations, diet, and ontogeny. [PDF]

open access: yesJ Anat
Extant 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

Phylogenetic analysis of a new morphological dataset elucidates the evolutionary history of Crocodylia and resolves the long-standing gharial problem [PDF]

open access: yesPeerJ, 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.

Ocorrência da Icnoespécie Nihilichnus nihilicus Mikulás, Kadlecová, Fejfar & Dvorák (2006) em Vértebra de Crocodylia da Formação Solimões (Mioceno Superior da Bacia do Acre) [PDF]

open access: yesAnuário do Instituto de Geociências, 2020
Os aspectos icnológicos relacionados a substrato ósseo da Formação Solimões (Mioceno superior da Bacia do Acre) ainda são pouco conhecidos. Um estudo tafonômico recente dos fósseis desta unidade disponíveis no acervo do Museu de Ciências da Terra da ...
