The relatively large size of most dinosaurs and the low diversity of small-bodied dinosaur species at the end of the Cretaceous may have contributed to their extinction; [277] the extinction of the bird lineages that did not survive may also have been caused by a dependence on forest habitats or a lack of adaptations to eating seeds for survival.
Some creationists further believe that dinosaurs survived the Biblical flood since the Bible states that "every kind of land animal" did. [12] Creationists also tend to reject the fossil evidence that many non-avian dinosaurs were feathered, since this is among the evidence that birds descended from them through evolution. [14]

Diversification in small, ornithischian dinosaurs: heterodontosaurids, fabrosaurids, and scelidosaurids. 190 Ma Pliosauroids appear in the fossil ...
The research suggested that meat-eating theropods, which included T. rex, and plant-eating ornithischians, such as Triceratops and Stegosaurus, spread to live in colder climates during the early ...
Dinosaurs were initially cold-blooded, but global warming 180 million years ago may have triggered the evolution of warm-blooded species, a new study found.
What type of dinosaur it belonged to is unknown, but there have been suggestions that it was from Allosaurus. "Beelemodon": Known only from two teeth found in Wyoming. They share features of compsognathids, dromaeosaurids and basal oviraptorosaurs. "Capitalsaurus": The official dinosaur of the District of Columbia. It is known from a single ...
Dinosaurs evolved partway through the Triassic period of the Mesozoic era, around 230 Ma (million years ago). At that time, the earth had one supercontinental landmass, called Pangaea , of which Europe was a part.
The poll, inspired by the release of the new 'Jurassic World' movie, asked, "Do you believe that dinosaurs and humans once lived on the planet at the same time?" Of the 1,000 people who were ...
