A new long‐necked archosauromorph from the Guanling Formation (Anisian, Middle Triassic) of southwestern China and its implications for neck evolution in tanystropheids
A long neck is an evolutionary innovation convergently appearing in multiple tetrapod lineages, including groups of plesiosaurs, non-archosauriform archosauromorphs, turtles, sauropodomorphs, birds, and mammals. Among all tetrapods both extant and extinct, two Triassic archosauromorphs, Tanystropheus and Dinocephalosaurus, have necks that are particularly elongated relative to the lengths of their trunks....Wang, Wei ; Spiekman, Stephan N F ; Zhao, Lijun ; Rieppel, Olivier ; Scheyer, Torsten M …

Scientists, collectors and illustrators: the roles of women in the Palaeontographical Society
Women have taken on a range of roles in scientific societies since the early twentieth century. The oldest society dedicated to palaeontology, the Palaeontographical Society, was established in 1847 principally for the publication of monographs on British fossils. Since its foundation, women have been involved, initially as collectors and illustrators,... -

Paranasal sinus system and upper respiratory tract evolution in Mesozoic pelagic crocodylomorphs
Thalattosuchians were a predominately marine clade of Mesozoic crocodylomorphs, including semi-aquatic teleosauroid and obligately pelagic metriorhynchid subclades. Recent advances in our understanding of thalattosuchian endocranial anatomy have revealed new details of the evolutionary transition from terrestrial to marine to pelagic taxa. Paranasal sinuses, however, have received little attention. Herein, we...Cowgill, Thomas ; Young, Mark T ; Schwab, Julia A ; Walsh, Stig ; Witmer, Lawrence M …

Rostral neurovasculature indicates sensory trade‐offs in Mesozoic pelagic crocodylomorphs
Metriorhynchoid thalattosuchians were a marine clade of Mesozoic crocodylomorphs that evolved from semi-aquatic, “gharial”-like species into the obligately pelagic subclade Metriorhynchidae. To explore whether the sensory and physiological demands of underwater life necessitates a shift in rostral anatomy, both in neurology and vasculature, we investigate the trigeminal innervation and potential...Bowman, Charlotte I W ; Young, Mark T ; Schwab, Julia A ; Walsh, Stig ; Witmer, Lawrence M …

One unique group of crocodylomorphs are the thalattosuchians, which lived during the Jurassic and Cretaceous (ca. 191–125 Ma).
