In fact, there is also a creature that has few scenes, but often surprises and shocks the audience. That's the Mosasaurus that dominates the underwater world. In the movie, it is shown that its body is extremely large, its bloody mouth full of fangs can swallow sharks in one bite, and it can even drag land-based dinosaurs into the water to kill. However, these are not unsubstantiated telemarketing list fictitious plots, and based on current archaeological evidence, the descriptions in the film are quite correct. This episode of "Zero Distance Science" will give you an in-depth introduction to this prehistoric underwater behemoth. Dino_2_9 If the tyrannosaurus traveled near the sea, it might be dragged into the sea by the mosasaur and drowned. In the water, the mosasaur is definitely the tyrant. Although the mosasaur is called "dragon", according to the taxonomy, it is not the dinosaur (Dinosaur) that we are familiar with. Both mosasaurs and dinosaurs belong to Sauria, but the former belongs to Lepidosauromorpha, and the latter belongs to Archosauromorpha. To put it simply, mosasaurs belong to the Squamata order, and are more similar to lizards and snakes; while dinosaurs are more similar to crocodiles. Mosasaurus rose at the end of the Cretaceous period, and at the same time as the dinosaurs, one dominated the ocean, one male dominated the ground, and two males divided the world. Dino_2_7 Mosasaurs are not dinosaurs. The former is closer to a snake, and the latter is closer to a crocodile.
