Big Events

K-T Mass Extinction, which occurred at the end of the Cretaceous Period. Nearly 75% of species living at that time were extinct. Though not the largest extinction of it’s time, it was what ultimately took out the dinosaurs. The suspected cause of this was extreme asteroid or meteor impact. This was found by scientists studying craters left by the asteroids.
