The locomotor ecomorphology of Mesozoic marine reptiles
Palaeontology, Volume 66, Issue 2, March/April 2023., 2023 Abstract The aftermath of the end‐Permian mass extinction provided ecological opportunities for many groups of reptiles, marking the beginning of reptile dominance of the Mesozoic oceans. Clades such as ichthyosaurs, thalattosuchians, sauropterygians, mosasaurs and turtles evolved a remarkable diversity of ecological niches and became important ...

Biological Reviews, Volume 97, Issue 2, Page 766-801, April 2022., 2022 ABSTRACT 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 believed that its earliest appearances in birds and mammals arose many millions of years apart.

Biological Reviews, Volume 96, Issue 5, Page 2229-2257, October 2021., 2021 ABSTRACT The morphology of the temporal region in the tetrapod skull traditionally has been a widely discussed feature of vertebrate anatomy. The evolution of different temporal openings in Amniota (mammals, birds, and reptiles), Lissamphibia (frogs, salamanders, and caecilians), and several extinct tetrapod groups has sparked debates on the ...

Peculiar macrophagous adaptations in a new Cretaceous pliosaurid [PDF]
Royal Society Open Science, 2015 During the Middle and Late Jurassic, pliosaurid plesiosaurs evolved gigantic body size and a series of craniodental adaptations that have been linked to the occupation of an apex predator niche. Cretaceous pliosaurids (i.e.

The origin of the turtle body plan: evidence from fossils and embryos
Palaeontology, Volume 63, Issue 3, Page 375-393, May 2020., 2020 Abstract The origin of the unique body plan of turtles has long been one of the most intriguing mysteries in evolutionary morphology. Discoveries of several new stem‐turtles, together with insights from recent studies on the development of the shell in extant turtles, have provided crucial new information concerning this subject.

Journal of Anatomy, Volume 236, Issue 4, Page 630-659, April 2020., 2020 The skull of a well preserved specimen of Champsosaurus lindoei was computed tomography (CT) scanned to describe the cranial elements and comment on the putative choristoderan neomorphic bone. These data provide the first exhaustive description of a choristodere skull using CT scanning, and confirm the presence of the neomorphic bone lateral to the ...
