Dinosaur (English name: Dinosaur) refers to Triceratops, modern birds and Liang Long's nearest ancestors and all their descendants. For the convenience of research, dinosaurs can be divided into birds and non-bird dinosaurs. Among them, non-bird dinosaurs only lived in Mesozoic (Triassic, Jurassic and Cretaceous) and were all extinct 65 million years ago. This entry mainly introduces non-bird dinosaurs.

The vigorous limbs, long tail and huge body are the portrayal of some non-bird dinosaurs. They mainly inhabit woodland or open areas in lakeshore plains (or coastal plains).
