The Time Terror Birds Invaded
PBS Eons
Details
Share

About 5 million years ago, a new predator made its way from the south and onto the coastal plains of North America. It was a giant, flightless, carnivorous bird and came to be known by one of the coolest and most richly earned nicknames in all of paleontology: the terror bird.

Correction! Thanks to Ben Creisler for pointing out that at 4:10, we mixed up the Paleogene Period with the Neogene Period. We regret the error and hope you still find these birds as terrifying as we do.
