Information and knowledge about dinosaurs

Dinosaur is a sauropod that lived in Mesozoic. Dinosaurs can be divided into bird dinosaurs 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. The vigorous limbs, long tail and huge body are the portrayal of some non-bird dinosaurs, which mainly inhabit woodland or open areas on the lakeshore plain (or coastal plain).

184 1 year, when British scientist richard owen studied several lizard-like bone fossils, he thought they were left by some prehistoric animals and named them dinosaurs, which means "scary lizards".

Generally speaking, dinosaurs are very big. According to dinosaurs, sauropods were among them. In the long dinosaur era, even the smallest sauropods were larger than other animals in their habitats, while the largest sauropods were several grades larger than any animals that appeared on the surface.

Extended data

Life habits of dinosaurs:

First of all, foraging

The plants that herbivorous dinosaurs can eat are highly restricted, so some small herbivorous dinosaurs will stand on their hind legs in order to eat the leaves of tall plants. Carnivorous dinosaurs ate herbivorous dinosaurs and other animals. Various dinosaurs' different ways of foraging will also be reflected in their teeth. ?

Second, struggle.

Sharp teeth and claws are hunting weapons for carnivorous dinosaurs. Tyrannosaurus rex would look for individual herbivorous dinosaurs, so they often acted alone. And some dinosaurs will act in groups, lock in their prey and flock to them, and cut their prey's abdomen with their claws on the second toe.

Herbivorous dinosaurs generally have some special "equipment" to deal with the attack of carnivorous dinosaurs. These devices are sometimes tough leather armor, bone sticks or nails, and sometimes powerful tails. Large herbivorous dinosaurs will act collectively, and once threatened, they will collectively hold their ground and fight back.
