The whole‐body (tachymetabolic) endothermy seen in modern birds and mammals is long
held to have evolved independently in each group, a reasonable assumption when it was …

The colonisation of freshwater and marine ecosystems by land vertebrates has repeatedly
occurred in amphibians, reptiles, birds and mammals over the course of 300 million years …

During the Mesozoic, various groups of reptiles underwent a spectacular return to an aquatic
life, colonizing most marine environments. They were highly diversified both systematically …

Numerous amniote groups adapted to an aquatic life. This change of habitat naturally led to
numerous convergences. The various adaptive traits vary depending on the degree of …

Gigantism—very large body size—is an ecologically important trait associated with
competitive superiority. Although it has been studied in particular cases, the general …

Graviportal taxa show an allometric increase of the cross-sectional area of supportive bones
and are assumed to display microanatomical changes associated with an increase in bone …

Among living turtles, highly terrestrial or highly aquatic modes of life are likely to have
developed from a plesiomorphic semi-aquatic one. A taxonomically comprehensive data set …

Very large unidentified elongate and rounded fossil bone segments of uncertain origin
recovered from different Rhaetian (Late Triassic) fossil localities across Europe have been …

This paper is aimed at constraining the phylogenetic frame of the acquisition of endothermy
by Archosauromorpha. We analyzed the bone histology of Azendohsaurus laaroussii …

Observations of temporal overlap of niche occupation among Late Cretaceous marine
amniotes suggest that the rise and diversification of mosasauroid squamates might have …
