Smok has several features that are shared with both dinosaurs and crocodile-line archosaurs, making classification difficult. Similarities with theropods include a groove, or antitrochanter, on the ilium bone of the hip that is part of the acetabulum (a depression where the head of the femur attaches to the hip).
Rauisuchians are a category of archosaurs within a larger group called Pseudosuchia, which encompasses all archosaurs more closely related to crocodilians than to birds and other dinosaurs. First named in the 1940s, Rauisuchia was a name exclusive to Triassic archosaurs which were generally large (often 4 to 6 metres (13 to 20 ft)), carnivorous ...
The Children's Museum reopened its revamped Dinosphere in March of 2022, and it added several finds from the Big Horn Basin dig site. Those include two sauropods, about 65 feet long each; a marine ...
Dinosaurs evolved from archosaurs with this hip arrangement. The hip sockets faced downwards and the knobs on the femurs were in line with the femur. This "pillar-erect" arrangement appears to have evolved independently in various archosaur lineages, for example it was common in "Rauisuchia" (non-crocodylomorph paracrocodylomorphs ) and also ...
Scientists have found the U.K.’s largest dinosaur footprint site ever. The tracks were discovered in a quarry in Oxfordshire — about 60 miles northwest of London — by quarry employee Gary ...
Fragment of long bone of a dinosaur is described from the Upper Cretaceous (Santonian–Campanian) sediments near the village of Izhberda (Orenburg Oblast, Russia) by Skutschas et al. (2022), who interpret the histological features of this bone as indicative of rapid continuous growth known in large-sized dinosaurs, and interpret this finding ...
