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 ...
Archosaurus (meaning "ruling lizard") is an extinct genus of carnivorous proterosuchid archosauriform reptile. [1] Its fossils are dated to the latest Permian of Russia and Poland, it is one of the earliest known archosauriforms.
A study on the diversification of non-avian dinosaurs, inferred from available dinosaur phylogenies, is published by Allen et al. (2024), who find it impossible to decisively conclude whether dinosaurs experienced a decline in diversity before the Cretaceous–Paleogene extinction event on the basis of available data, noting the impact of the ...
A study on the duration of Late Cretaceous megaherbivore dinosaur assemblage zones in the 100 m thick stratigraphic section exposed at Dinosaur Provincial Park (Alberta, Canada) is published by Eberth et al. (2023), who interpret their findings as indicating that the dinosaur assemblage zones in the studied section had duration time of ~600 ...
A study on the diversity of form and function of teeth in early-diverging dinosaurs is published by Ballell, Benton & Rayfield (2022), providing evidence of a previously unrecognized functional diversity in the dentitions of early dinosaurs, and indicating that either carnivory or omnivory was the ancestral diet of dinosaurs, with obligate ...
A study on the impact of the disparity between neonates and adults on the structure and diversity of dinosaur communities is published by Schroeder, Lyons & Smith (2021), who claim that communities with giant theropods lacked carnivores weighing 100 to 1000 kg, and argue that juveniles of giant theropod species likely filled the mesocarnivore ...
Articles relating to the Archosaurs, a clade of diapsids, with birds and crocodilians as the only living representatives. Archosaurs are broadly classified as reptiles, in the cladistic sense of term which includes birds. Extinct archosaurs include non-avian dinosaurs, pterosaurs, and extinct relatives of
