Where did the terror birds live?

The "terror birds" (Phorusrhacidae) were large carnivorous Flightless Birds that lived in South America during the Cenozoic era (from about 2 to 60 million years ago).

Standing 1 to 3 meters (3-10 feet) in height, they were one of the dominant predators of their time. Their closest modern relatives may be the seriema birds of Brazil, Argentina, and Paraguay.
