Quick Bite: From Terror Bird to Gentle Giant
from Past Time Hosted by Adam Pritchard, Matthew Borths, Catherine Early
50 million-years ago, the heir to Tyrannosaurus stalked the forests of ancient Europe and North America, snapping up the tiny ancestors of horses, cows, and wolves in its colossal meat-cleaving beak. Gastornis was a six-foot-tall, flightless bird and the king of the food chain...or that’s what we thought. For decades paleontologists looked at the huge, parrot-like head and thought the giant bird must be a carnivore, but a recent, exhaustive study drew on molecular evidence, anatomical evidence, and ecological evidence to show Gastornis was a giant herbivore! The former terror bird likely used that massive beak to crack open the abundant seeds and leaves that would have littered the forest at the beginning of the Age of Mammals. Tune in to Past Time to learn how the fossil Terror Bird became Big Bird!
