Sedation and general anaesthesia of crocodilians: a systematic review [PDF]

Acta Veterinaria Scandinavica
Sedation and general anaesthesia of crocodilians pose unique challenges due to their aggressive nature, poikilothermic physiology, and specific anatomical and physiological characteristics, all factors that complicate crocodilian anaesthesia. This review

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

Anat 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.

Heterodonty in the teeth of the turiasaurian sauropod from Angeac-Charente (Early Cretaceous, southwestern France): Comparison of anatomical and geometric morphometric approaches. [PDF]

J Anat
Turiasaurian teeth from Angeac‐Charente exhibit five dental morphotypes and reveal clear heterodonty and anteroposterior size gradient. Qualitative comparative anatomy quickly and efficiently identifies morphotypes, while 3D geometric morphometrics combined with machine learning refine ambiguous cases, demonstrating that qualitative and quantitative ...

Putative avian teeth from the Late Cretaceous of Alberta, Canada, are more likely from crocodilians.

PLoS ONE, 2023
Isolated teeth, previously referred to Aves, are more common than other bird fossils from the Late Cretaceous of Alberta. However, there are no known morphological synapomorphies that distinguish isolated bird teeth, and features of these teeth are ...

Crocodylus porosus Gut Bacteria: A Possible Source of Novel Metabolites

Molecules, 2021
Crocodiles are remarkable animals that have the ability to endure extremely harsh conditions and can survive up to a 100 years while being exposed to noxious agents that are detrimental to Homo sapiens.

Drivers of human–black caiman (Melanosuchus niger) conflict in Indigenous communities in the North Rupununi wetlands, southwestern Guyana

Conservation Science and Practice, 2023
Recovering populations of large carnivores impact the people that live alongside them, sometimes leading to conflict and lethal retaliation. One such carnivore, the black caiman (Melanosuchus niger) has been implicated in the destruction of fishing ...

Hematological values of wild Caiman latirostris (Daudin, 1802) in the Atlantic Rainforest in Pernambuco, Brazil

Acta Herpetologica, 2021
Hematological studies in crocodilians are important tools in the evolutionary diagnosis and control of sicknesses, such as anaemia, malnutrition, dehydration, inflammation, and parasitism, among others.

Serum concentrations of corticosterone and sex hormones and their relationship in farmed Morelet’s crocodile (Crocodylus moreletii)

Revista Colombiana de Ciencias Pecuarias, 2022
Background: Crocodile farming aims to produce high-quality skins from captive crocodilians. Captivity usually exposes the animals to stressful conditions, resulting in increased serum corticosterone (CORT) levels that correlate negatively with those of ...

Carcass and commercial cuts yields of caiman (Caiman crocodilus yacare) farmed in a ranching system in the Brazilian Pantanal

Anais da Academia Brasileira de Ciências, 2021
Given the growing use of alternative sources of protein, studies on the commercial viability of amazonians wild species, based on the yield of their carcass, are still scarce in the literature.

T. rex cognition was T. rex-like-A critical outlook on diverging views of the neurocognitive evolution in dinosaurs. [PDF]

Anat Rec (Hoboken)
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...
