Dinosaurs are extinct reptiles that lived on the earth from 240 million to 65 million years ago. Here are some facts about dinosaurs:
1. Dinosaurs are divided into two main categories: ornithopods and sauropods.
2. Ornithopods are known for their long legs and speed. The most famous of these is Tyrannosaurus Rex in Delta Park.
3. Sauropods are known for their long necks and small heads. The most famous of these is the giant Brusselsaurus (Brachiosaurus).
4. Thalosaurus dinosaurs are one of the largest known carnivorous animals, larger than Dinosaur Rex.
5. The extinction of the dinosaurs may have been caused by a large-scale natural disaster. Some people believe that a meteorite hitting the earth caused this catastrophe.
6. According to fossil records, the earliest dinosaurs appeared in the early Triassic period about 240 million years ago, while the last dinosaurs became extinct at the end of the Cretaceous period about 65 million years ago.
7. In addition to dinosaurs, some other reptiles have also become extinct, such as saber-toothed tigers, pterosaurs, and giant sea lizards.
8. The discipline that studies dinosaurs is called paleontology. Through the study of dinosaur remains and fossils, we can learn about their living habits, eating habits, appearance, and evolutionary processes.
