Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

open access: yesBiological Reviews, EarlyView.
ABSTRACT 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.

Micronuclei and Nuclear Buds Induced by Cyclophosphamide in Crocodylus moreletii as Useful Biomarkers in Aquatic Environments

open access: yesAnimals, 2021
Micronuclei (MN) are used to assess genotoxic exposure, whereas nuclear buds (NBs) have been linked to genotoxic events. Crocodylus moreletii was studied to identify MN and NBs.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Biometric observations of newborn Crocodylus acutus (Cuvier, 1807) obtained in captivity in, Tumbes, Peru

open access: yesRevista Peruana de Biología, 2013
In this paper, length and weigth measurements of 20 newborn Crocodylus acutus (Cuvier, 1807) hached in a pilot farm-bred of the aquaculture center La Tuna Carranza, Puerto Pizarro, Tumbes, Peru, in 2001 are presented.

Radiographic evaluation of gastroliths in a group of 49 juvenile saltwater crocodiles (Crocodylus porosus) in the UK

open access: yesVeterinary Record, EarlyView.
Abstract Background Gastrolith ingestion is a known inherent behaviour in crocodiles. However, the interpretation of coelomic radiographs in crocodilians is challenging due to the limited informative literature in this field. Methods Dorsoventral coelomic radiographs of 49 juvenile saltwater crocodiles (Crocodylus porosus) were acquired twice, with an ...

Seasonal variations and challenges in estimating populations and identifying species of Korean ungulates using drone‐derived thermal orthomosaic maps

open access: yesWildlife Biology, EarlyView.
Drones equipped with thermal infrared (TIR) cameras offer significant time and labor savings in estimating wild ungulate populations. However, accurately monitoring forest‐dwelling ungulates remains challenging due to their elusive behavior and complex habitat.

Quadrate orientation and joint reaction force underwent correlated evolution during suchian evolution

open access: yesJournal of Anatomy, EarlyView.
The quadrate is the cranial bone of the nonmammalian jaw joint. The quadrate has long been hypothesized to mirror the direction of joint reaction forces (JRF) during feeding. This study uses 3D biomechanical modeling to reveal a striking evolutionary link between quadrate orientation and JRF direction, unlocking new insights into the dynamic forces ...

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

open access: yesJournal of Anatomy, EarlyView.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...
