Holy shit, this is so mind-boggling, how did the dinosaurs become extinct?

Killed by pigs

The reason is: a long time ago, dinosaurs existed, and then there was a sudden flood, and God built a ship called Noah's Ark, but The boat couldn't carry too many animals, so God told the animals to tell jokes and fight with each other. Otherwise, they would drown. There are thirteen seats on the boat, the first twelve are occupied by the twelve zodiac animals, and the last seat is occupied. At this time, the dinosaur appears. He tells a joke and everyone laughs. But only the pig does not laugh. There is no way for the dinosaur to commit suicide by jumping into the water. It's the human's turn and the human hasn't said anything yet. The pig laughed: Hahaha... The dinosaur joke is so funny... (Pigs are slow to react)
