Titanis walleri (Velizar Simeonovski)

A Titanis walleri catches a Felis rexroadensis who tried to raid her nest in Pliocene North America.

Titanis walleri was the only known Terror Bird, from the family Phorushacidae, that managed to invade North America when the isthmus linking North and South America formed.

They stood about 2.5 meters tall.
