|Scientific name||Gastornis parisiensis|
The Diatryma (now known as the Gastornis) is a prehistoric bird that flourished right after the extinction of the dinosaurs. The bird had degenerated wings, meaning that it couldn't take flight. With a large head and a hooked shaped beak, it could run at speeds of 70 km/hr. It hunted by dashing towards and kicking its prey. Back then, it was one of the most fearsome birds.
