The Chicxulub Impact or also named Cretaceous–Tertiary (K–T) extinction was the impact of an asteroid that was 10 kilometers wide. This impact is the most well known due to being responsible (Or partially responsible) of wiping out the big dinosaurs, the large birds and most species of plants.
Only the mammals (Which during this time period, were very small so they didn't require a lot of food and could survive by digging tunnels), some types of reptiles (Which survived by eating those small mammals or eating insects), some birds and the insects (Which survived by eating the rotting plants and large animals) managed to survive this impact.
