Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology. [PDF]
Biol Rev Camb Philos SocABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

A Body Condition Score for Crocodilians
South American Journal of Herpetology, 2020 . Body condition (BC) has been used extensively to evaluate fitness in animals. In traditional studies of crocodiles, the paradigm of evaluating BC with the Fulton index and interpreting the results with quartiles is predominant.

The Anatomical Record, EarlyView.Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Volume of the crocodilian brain and endocast during ontogeny. [PDF]
PLoS ONE, 2017 Understanding complex situations and planning difficult actions require a brain of appropriate size. Animal encephalisation provides an indirect information about these abilities.

Journal of Developmental Biology, 2021 The ability to repair injuries among reptiles, i.e., ectothermic amniotes, is similar to that of mammals with some noteworthy exceptions. While large wounds in turtles and crocodilians are repaired through scarring, the reparative capacity involving the ...

Distribution of Endogenous Retroviruses in Crocodilians [PDF]
Journal of Virology, 2009 ABSTRACT Knowledge of endogenous retroviruses (ERVs) in crocodilians (Crocodylia) is limited, and their distribution among extant species is unclear. Here we analyzed the phylogenetic relationships of these retroelements in 20 species of crocodilians by studying the pro-pol gene.

Ontogeny of murine bony semicircular canal form
The Anatomical Record, EarlyView.Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Cytochrome oxidase I DNA barcode database of crocodilians meat selling in Hong Kong
, 2023 The crocodilians include true crocodiles, alligators, caimans, and gharial, and the trade of crocodilian products is regulated in accordance with the Convention of Wild Fauna and Flora (CITES). Hong Kong does not have her own wild crocodilians; thus, all
