There are 64 species, including Tyrannosaurus Rex, Golden Dinosaur, Big Flower Dinosaur, Spotted Dinosaur, Blue Dinosaur, Grass Rope Dinosaur, Tiger-striped Dinosaur King, Crocodile Dinosaur King, Golden Dinosaur King, Congo Dinosaur King and so on. . Divide men and women by gender! In terms of species, it is estimated that there are about 900~ 1200 species of dinosaurs, and scientists believe that the dinosaurs that have been discovered are about 1/4 of the dinosaurs that once existed.

Dinosaurs were a huge family in Mesozoic, and they ruled the animal kingdom at that time.

In time, dinosaurs lived for 65.438+0.6 billion years; In terms of distribution, the footprints are spread all over seven continents.

However, most dinosaurs were found in the United States, Mongolia, China, Canada, Britain and Argentina.

There are 64 genera of dinosaurs found in the United States, ranking first in the world. There are 40 genera in Mongolia, 36 genera in China, 3 1 genus in Canada, 26 genera in Britain and 23 genera in Argentina. Animals that are similar to each other belong to the same "genus" in taxonomy, such as cats, tigers, lions and leopards, but they belong to different species. ) Most dinosaurs have only 1 species, and a few dinosaurs have 2 or 3 species. According to statistics, there are 285 dinosaur genera found at present, each with 336.

We don't think this is the actual number of dinosaurs that once lived on the earth. There are still a large number of dinosaur bones buried deep underground, which have not yet been discovered. There are also many dinosaurs who may have walked in the world for nothing and left nothing behind after their death.

Professor dodson of the University of Pennsylvania studied how to estimate the genus number of dinosaurs that have lived on the earth for many years. He estimated that 900- 1200 dinosaurs once lived on the earth. But only part of it was discovered. But after the discovery, few people explored and studied it carefully.

According to dodson, the number of dinosaurs we have discovered is about the actual number 1/3- 1/4. This shows that the task before dinosaur experts is still quite huge, and the discovery and research of dinosaurs have a long way to go. With the deepening of dinosaur research, new dinosaur genera and species will be discovered continuously.
