Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

The comparative energetics of the turtles and crocodiles. [PDF]

open access: yesEcol Evol, 2022
This paper discusses patterns in Dynamic Energy Budget parameters and implied traits that we found for turtles and crocodiles. We explain, for instance, why the proportionality of weight at birth with the square root of ultimate weight points to problems with water loss and nitrogen‐waste accumulation.

Roars, Rumbles, and Resonance: A Systematic Review and Meta-Analysis of Crocodylian Acoustic Signals. [PDF]

open access: yesEcol Evol
Crocodylians are highly vocal reptiles, possessing a complex acoustic signalling system including vocal and non‐vocal signals used for courtship, mating, mediating conflict, and providing maternal care. Despite this, research on crocodylian acoustic signalling remains infrequent, with methodologies and terminology varying widely across studies.

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

Neuroanatomy of the mekosuchine crocodylian Trilophosuchus rackhami Willis, 1993. [PDF]

open access: yesJ Anat, 2022
This study described the neuroanatomy of the mekosuchine crocodylian Trilophosuchus rackhami from the Middle Miocene of Australia. Although the neuromorphology of Trilophosuchus rackhami follows the general patterns seen in crocodylomorphs, it is nevertheless characterized by a unique combination of features that stand out among currently known taxa ...

Crecimiento del caimán del Orinoco (Crocodylus intermedius, Crocodylia: Crocodylidae) en dos condiciones de cautiverio

open access: yesRevista de Biología Tropical, 2006
para determinar el crecimiento del caimán del Orinoco (Crocodylus intermedius), en diferentes condiciones de cautiverio, se criaron 40 ejemplares durante 11 meses y 15 días. Se utilizaron dos tanques circulares, con una superficie de 28.3 m² y un volumen de 62.2 m³, construidos con bloques de concreto y protegidos con techo de láminas galvanizadas e ...

The velar chord and dynamic integration of the gular valve in crocodylians. [PDF]

open access: yesAnat Rec (Hoboken)
Crocodilians have a unique gular valve that forms a seal between the oral cavity and the pharynx. The gular valve has traditionally been treated as two parts: a mobile ventral flap associated with the tongue and a fixed dorsal velum palatini. This work describes a connective tissue band, the velar chord, which functionally integrates the two parts of ...

Septal deviation in the nose of the longest faced crocodylian: A description of nasal anatomy and airflow in the Indian gharial (Gavialis gangeticus) with comments on acoustics. [PDF]

open access: yesAnat Rec (Hoboken), 2022
Abstract The remarkably thin rostrum in the Indian gharial (Gavialis gangeticus) imparts challenges to nasal physiology. Competition for space in the slim jaws necessitates a thin nasal septum, leaving this taxon susceptible to nasal passage abnormalities such as septal deviation.

Informe ecológico regional caracterización ecológica en lagunas para posible cautiverio del caimán llanero (Crocodylus intermedius) [PDF]

open access: yes, 2007
Los estudios poblacionales del caimán llanero se iniciaron a partir del año de 1975 por Federico Meden quién financiado por World Wildlife Fund, determinó la presencia de 280 individuos observados directamente y otros 780 estimados para un área de 252.530 Km2 que incluía a los departamentos de Arauca, Casanare, Meta y Vichada. Entre 1994 y 1997, la

Perfil bioquímico y hematológico del cocodrilo del Orinoco (Crocodylus Intermedius) y tortugas acuáticas mantenidas en condiciones ex-situ [PDF]

open access: yes, 2020
Colombia es el cuarto país con la mayor diversidad de reptiles a nivel mundial. A pesar de esta riqueza y el importante papel ecosistémico de los reptiles, la sobreexplotación para el consumo, la destrucción y transformación de su hábitat y su extracción para el comercio de mascotas, han causado que gran parte esta biodiversidad y, especialmente ...
