Just before the K-Pg extinction event, the number of non-avian dinosaur species that existed globally has been estimated at between 628 and 1078. [280] It remains uncertain whether the diversity of dinosaurs was in gradual decline before the K-Pg extinction event, or whether dinosaurs were actually thriving prior to the extinction.
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
Three species have been named, each with a unique pattern of cranial ornamentation Palaeoscincus: 1856 Judith River Formation (Late Cretaceous, Campanian) United States ( Montana) Although many restorations depict it with the spikes of Edmontonia and the tail club of Ankylosaurus, this is most likely incorrect Panoplosaurus: 1919

A previously unknown species of plant-eating dinosaur roamed on an island off the south coast of England around 125 million years ago, new research has found. UK’s most complete dinosaur fossil ...
The results of this study, which were based on estimated real global biodiversity, showed that between 628 and 1,078 non-avian dinosaur species were alive at the end of the Cretaceous and underwent sudden extinction after the Cretaceous–Paleogene extinction event. [136]
Originally believed to have lived in a marshy environment Euronychodon: 1991 Bissekty Formation (Late Cretaceous, Turonian) Uzbekistan: The type species was found in Portugal. The Asian species may represent a form taxon of improperly developed teeth [43] Ferganasaurus: 2003 Balabansai Formation (Middle Jurassic, Callovian) Kyrgyzstan
Brazil's geological service on Thursday announced a new species of dinosaur, a speedy animal that lived in the desert during the early Cretaceous period. The new species, called Farlowichnus ...
