Staphylococci, Reptiles, Amphibians, and Humans: What Are Their Relations?
PathogensReptiles and amphibians are largely present in many environments, including domestic areas when they are kept as pet animals. They often harbor zoonotic pathogens, which can pose a serious risk of infection for humans, mainly immunocompromised ...

Crocodilians in Perspective! [PDF]
American Zoologist, 1989 The prediction of the 1960s that crocodilians would soon be extinct has happily proven to be unduly pessimistic. The survival and recovery of substantial stocks provides us with the unexpected opportunity to learn about their adaptations, important not only because of their place as relicts of a major reptilian radiation, but also as giant animals ...

Journal of Vertebrate Paleontology, 2019 Crocodilian remains from the Oligocene fossil locality of Monteviale, northeastern Italy, have historically been referred to different genera, but all material was recently assigned to Diplocynodon cf. D. ratelii Pomel, 1847.

The Anatomical Record, EarlyView.Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

The Anatomical Record, EarlyView.Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Density and Biomass Estimates by Removal for an Amazonian Crocodilian, Paleosuchus palpebrosus. [PDF]
PLoS ONE, 2016 Direct counts of crocodilians are rarely feasible and it is difficult to meet the assumptions of mark-recapture methods for most species in most habitats.

The Anatomical Record, EarlyView.Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Low temperatures reduce skin healing in the Jacaré do Pantanal (Caiman yacare, Daudin 1802)
Biology Open, 2013 Summary Studies of skin wound healing in crocodilians are necessary given the frequent occurrence of cannibalism in intensive farming systems. Air temperature affects tissue recovery because crocodilians are ectothermic.

The Anatomical Record, EarlyView.Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

A chimeric vaccine protects farmed saltwater crocodiles from West Nile virus-induced skin lesions
npj Vaccines, 2023 West Nile virus (WNV) causes skin lesions in farmed crocodiles leading to the depreciation of the value of their hides and significant economic losses. However, there is no commercially available vaccine designed for use in crocodilians against WNV.
