Adriel Lloyd · Answer 1

Cambrian explosion

Dominance of amphibians

Earth hit by a large carbonaceous material

Extinction of giant mammals like mastodons

Diversification and dominance of mammals

Cambrian explosion level to sudden increase in diversity that lead to the competition and extinction of species.

This led to origin of amphibian in demonian period and in the cretaceous period about B5 a carbonaceous meteorite hit earth lead cretaceous extinction including giant dinosaurs then in the tertiary period and Eocene epoch mammals originate.
