The teeth of dinosaurs resemble horse teeth

A new study by a team at the University of Florida (USA) led by Dr. Gregory shows that a dinosaur-like herb with a giant lizard-like shape has complex teeth like horse teeth, chewing power They are very similar to mammals.

Dr. Gregory said that the chewing power of this herbivore is even greater than that of mammals such as horses, elephants and buffaloes. This finding contributes to the evidence that herbivorous dinosaurs are the last extinct dinosaurs on two continents of Asia and North America. They lived at the end of the Cretaceous about 65 million years ago, with mines such as duckbills, specializing in all kinds of grass and conifers, ancient ferns, coniferous parts.

Because their food has a hard shell, they must chew very carefully, gradually their teeth evolve almost like the teeth of horses, elephants, buffalo.'I think this kind of dinosaur can eat any plant,' said Dr. Gregory. Mammals can chew more closely so that their teeth also have similar stiffness, while reptilian teeth are relatively simple, only enamel and hard bone. However, after laser scanning the surface of the teeth, it shows that the teeth of the herbivore are much more complicated than the reptiles even mammals.

They also found that the teeth in different positions had different shapes and hardness, the effect of chewing with teeth would make the herbivorous dinosaur population larger. Dr. and his team decided to use this analytical method to study extinct reptiles and mammals whose teeth are not fully preserved, because 'comes even the principle. The chewing of the horse has not been clarified yet , ' he said.
