Ten-foot-tall prehistoric "terror bird" had a fearsome bite
Terror birds were giant flightless carnivores that may have stood up to
10 feet tall (3 meters) and were armed with massive, fearsome skulls.
Scientifically known as phorusrhacids, some 18 known species of these
predators evolved about 60 million years ago in South America, confined
to what once was an island continent until the last few million years.
Feeding on a diversity of strange, now-extinct mammals and competing
with the likes of saber-tooth cats and marsupials, terror birds became
top predators wherever they roamed. At least one gigantic terror bird,
Titanis, eventually invaded North America about two to three million
years ago, but the animals disappeared from Earth shortly after.
