The difference between carnivorous dinosaurs and herbivorous dinosaurs
We heard a lot about dinosaurs when we were young, and they were published in many picture books and books. So do you know the difference between carnivorous dinosaurs and herbivorous dinosaurs? Let's have a look!
I. the difference between carnivorous dinosaurs and herbivorous dinosaurs
The ratio of head to body is different. The proportion of skulls is more than half of the body is carnivorous dinosaurs, on the contrary, if the proportion of skulls is not half of the body is herbivorous dinosaurs.
Second, specific introduction
1. Carnivorous dinosaurs had large heads and mouths, and large, curved teeth in their mouths. For example, the Yongchuan dragon found in Sichuan, China, has sharp serrated, backward curved teeth. Tyrannosaurus Rex, on the other hand, has sword-like teeth and serrated edges, the longest of which is up to 20 centimeters.
2. The teeth of vegetarian dinosaurs were flat and straight, without sawtooth, and could only be used for chewing. The shape and size of the teeth of vegetarian dinosaurs depend on the plants they ate. Sauropod dinosaurs, for example, had spoon-shaped or nail-shaped teeth that made it easy to cut stems and leaves. This is because they mainly eat cycads and ferns. The duck-billed dinosaur mainly ate the stone pine plant Equisetum, which contains more silicon and is very hard, so the duck-billed dragon's mouth has teeth up and down, one after another, densely lined up in many rows, up to more than 2000 at most. This is an adaptation to long-term hard food.
