Terror Birds, more formally Phorusrhacids, were carnivorous flightless birds of the Cenozoic era. Numerous species existed throughout North and South America, and they were apex predators for roughly 25 million years until dying out 2.5 million years ago at the beginning of the Pleistocene.

Phorusrhacidae - Wikipedia, the free encyclopedia

Phorusrhacids, colloquially known as terror birds, are an extinct clade of large carnivorous flightless birds that were the largest species of apex predators in South America during the Cenozoic era; their temporal range covers from 62 to 1.8 million years (Ma) ago.
