Enigmatic dinosaur precursors bridge the gap to the origin of Pterosauria [PDF]
Nature, 2020 Pterosaurs were the first vertebrates to evolve powered flight1 and comprised one of the main evolutionary radiations in terrestrial ecosystems of the Mesozoic era (approximately 252-66 million years ago), but their origin has remained an unresolved enigma in palaeontology since the nineteenth century2-4. These flying reptiles have been hypothesized to

An early juvenile of Kunpengopterus sinensis (Pterosauria) from the Late Jurassic in China [PDF]
Anais da Academia Brasileira de Ciências, 2021 The Wukongopteridae is a transitional clade between the long- and short-tailed pterosaur groups, and at least ten specimens have been studied without a determined juvenile specimen. Here, we described a small-sized Kunpengopterus sinensis, less than half the size of the holotype, which is the smallest specimen in wukongopterids.

Palaeontology, Volume 65, Issue 3, May/June 2022., 2022 Abstract Little is known about the large‐scale evolutionary patterns of skull size relative to body size, and the possible drivers behind these patterns, in Archosauromorpha. For example, the large skulls of erythrosuchids, a group of non‐archosaurian archosauromorphs from the Early and Middle Triassic, and of theropod dinosaurs are regarded as ...

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.

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia. [PDF]
J AnatHere, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

A REEXAMINATION OF FOUR PROLACERTIFORMS WITH IMPLICATIONS FOR PTEROSAUR PHYLOGENESIS
Rivista Italiana di Paleontologia e Stratigrafia, 2000 Traditionally, pterosaurs have been included within the Archosauriformes and many contemporary workers consider the Pterosauria the sister group to Lagosuchus, Scleromochlus and the Dinosauria.

A specimen of Rhamphorhynchus with soft tissue preservation, stomach contents and a putative coprolite [PDF]
PeerJ, 2015 Despite being known for nearly two centuries, new specimens of the derived non-pterodactyloid pterosaur Rhamphorhynchus continue to be discovered and reveal new information about their anatomy and palaeobiology.
