Evidence of cryptic lineages within a small South American crocodilian: the Schneider’s dwarf caiman Paleosuchus trigonatus (Alligatoridae: Caimaninae)

PeerJ, 2019
Schneider’s dwarf caiman Paleosuchus trigonatus is one of the smallest living crocodilians. Due to its broad distribution, cryptic behavior, and small home range, the species is well suited for the study of phylogeographic patterns on a continental scale.

A proxy for brain‐to‐endocranial cavity index in non‐neornithean dinosaurs and other extinct archosaurs

Journal of Comparative Neurology, Volume 532, Issue 3, March 2024.
Illustration of the endocranial doming, which can provide a proxy for the brain‐to‐endocranial cavity index, using the endocast of an adult of the iguanodont dinosaur Proa valdearinnoensis as an example. Abstract Although the brain fills nearly the entire cranial cavity in birds, it can occupy a small portion of it in crocodilians.

Caiman CF. Latirostris (Alligatoridae, Caimaninae) in the late miocene Palo Pintado formation, Salta province, Argentina: paleogeographic and paleoenvironmental considerations [PDF]

, 2014
The three recognized species of Caiman –C. latirostris, C. yacare and C. crocodilus– currently live in northern and central South America. Except for the fragmentary dentary of a putative Caiman from Oligocene rocks in Brazil, the genus has been reliably

Skeletogenesis of the pelvic girdle and pelvic members in embryos of Caiman yacare (Crocodylia: Alligatoridae)

Scientific Research and Essays, 2013
Caiman yacare embryos were collected and subjected to the bone cleared and Alizarin staining to analyze the ontogenic patterns of the skeletal ossification of the pelvic girdle and members. Ossification of C. yacare pelvis begins at 36 days of incubation. The femur, tibia and fibula present simultaneous stain retention at 30 days.

Taxon representative adult bite forces for extant Crocodylia with respect to mean body mass and the relationship between rostral proportion and force generation.

, 2013
(A) Members of the Alligatoridae are shown in blue, and members of the Crocodylidae+Gavialidae in green. The OLS regression equation describes the strong correspondence between body mass and bite force.

Baraminic analysis of Crocodylia based on mitochondrial DNA similarity

, 2023
Crocodiles, alligators, caimans, and gharials are interesting reptiles that are distinctly different from all other reptiles. These animals can be classified into three families within the order Crocodylia: Alligatoridae (alligators and caimans ...

Brazilian Journal of Biology, 2010
We surveyed populations of the broad-snouted caiman, Caiman latirostris, throughout the São Francisco River basin, from Três Marias reservoir, State of Minas Gerais, to the river delta, at the boarder of Sergipe and Alagoas states.
