What did dinosaurs who survived the extinction evolve into?

A commonly held scientific theory is that surviving dinosaurs evolved into birds.


What percentage of marine life made it through the mass extinction which knocked out the dinosaurs?

Scientists think that a few members of 84 percent of marine families survived the extinction, as did a few members of 82 percent of land vertebrates.


What do scientists believe helped contribute to the mass extinction event that knocked off the dinosaur population?

Some theorists claim that widespread volcanic eruptions also added to the unlivable conditions that caused the extinction of the dinosaur population.


At the end of which period did dinosaurs become extinct?

Dinosaurs lived during the Mesozoic era of the earth's history, which is divided into three periods: the Triassic, Jurassic and Cretaceous. They became extinct at the end of the Cretaceous period.


What was the age of mammals called?
