Article Synopsis
- Paleophysiology, a new field, emphasizes an organismic approach to studying the relationships among traits in creatures, rather than isolating specific features; this study focuses on the lower Jurassic thalattosuchian Pelagosaurus typus.* -
- The findings indicate that Pelagosaurus was amphibious, foraging in shallow marine areas while also basking on land, supported by unique physical features like salt glands and ornate osteoderms.* -
- Although Pelagosaurus exhibited a higher resting metabolic rate compared to modern ectothermic reptiles, it was not endothermic; its hunting style likely involved slow swimming or ambushing prey in shallow waters similar to modern crocodilians.*
The clade Pseudosuchia appeared 250 million years ago. The exclusively semi-aquatic Crocodylia, which includes crocodiles, alligators, caimans, and gharials is the only surviving subgroup. Investigating Crocodylia biology is pivotal for inferring traits of extinct pseudosuchians.

In this study we provide a comprehensive investigation of the microanatomical and microstructural aspects of the carapace and limb bones of the Early Cretaceous side-necked turtle, Araripemys barretoi, from the Araripe Basin, Brazil. Inter-elemental histovariability reveals different secondary remodelling of the skeletal elements within the same individual. The vascularisation is scarce and mainly longitudinal, also it ceases towards the bone surface, forming an avascular parallel-fibred bone with closely spaced LAGs.
