Dinosaurs are also divided into herbivorous dinosaurs and carnivorous dinosaurs. For example, Tyrannosaurus Rex is a fierce carnivore. According to modern archaeological analysis, Tyrannosaurus Rex was a dinosaur at the top of the food chain at that time, with strong legs and sharp teeth that could crush bones. Tyrannosaurus rex ate herbivorous dinosaurs.
Dinosaurs refer to the common ancestor of Triceratops, modern birds and Liang Long 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).
