first theory: the dinosaurs were killed because they were late paying their taxes.

second theory: the dinosaurs were killed because they were too distracted taking selfies to notice the giant asteroid hurtling towards them.

Third theory: The dinosaurs were killed because the Aliens came down with their UFOs and killed all the dinosaurs with their laser guns for fun.

The initial impact killed off a lot of Dino's. The 'dust' after the impact blocked the sun light. Plants didn't grow > Herbivores died > Carnivores died. 🤷‍♂️
