Researchers including a Johns Hopkins University evolutionary biologist report they have analyzed a fossil of an extinct giant meat-eating bird—which they say could be the largest known member of its kind—providing new information about animal life in northern South America millions of years ago.

Terror birds were apex predators some 12 million years ago in South America. A newly published discovery could be the largest yet.

A Colombian rancher has discovered a fossilized bone that points to the existence of a giant terror bird species. The fossil, an enormous leg bone found in the Tatacoa Desert, suggests that this bird stood over three meters tall,

A massive meat-eating bird sat high atop the food chain about 12 million years ago. Researchers analyzed a bone of the creature found in northern South America nearly 20 years ago and determined that it was likely a "terror bird" related to Phorusrhacids,

The fossil was on display in a museum, but unlabeled and hidden right under paleontologists’ noses for 20 years.

While past terror bird fossils placed the meat-eating birds at 3 to 9 feet tall, new findings suggest that some were even bigger
