Teratornis is a prehistoric genus of giant vulture from Pleistocene North America. It was mostly a predator, hunting rabbits and other small prey. However, like its modern descendants, it was a scavenger, with many of them gathering around a carcass to feed.
In The Land Before Time
Teratornis appears as an enemy in The Land Before Time Math Adventure. In the game, it flies back and forth trying to attack a nest of eggs. Ducky and Cera can shoot a certain number of rocks at it to take it out.
