Review of studies of dinosaur reproduction and ontogeny, and of challenges in the studies of dinosaur reproductive biology, is published by Chapelle, Griffin & Pol (2025). [ 19 ] Deiques et al. (2025) report the discovery of new dinosaur tracks from the Upper Jurassic Guará Formation ( Brazil ), including second record of an ankylosaur track ...
Researchers have uncovered a "dinosaur highway" after hundreds of giant prehistoric footprints dating back 166 million years were found in an English quarry. Discovered at the Dewars Farm Quarry ...
Bones from other parts of the body were found in 2009 and 2010. Five tracks made by a three-toed archosaur – presumably a theropod dinosaur – were found in rocks that were 1 metre (3.3 ft) above the layer where Smok was found. The footprints may belong to Smok, but the lack of foot bones in the skeleton make this association uncertain. [1]
A crocodile-like creature bit the neck of a flying dinosaur some 76 million years ago – and scientists have proof. Archaeologists found the fossilized neck bone of the young pterosaur in Canada ...
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 ...
A rare dinosaur bone bed containing 115-million-year-old fossils has been unearthed in Maryland, officials and experts say. ... The first bone found at the park in 2018 was a 4-foot-long limb bone ...
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 ...
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 ...
