Though known only from a shinbone fragment, a newly-described flesh-eating terror just might be the largest known member of its feathered kind.

Phorusrhacid ‘terror birds’ stalked what’s now Colombia’s Tatacoa Desert around 12 million years ago, among car-sized armadillo relatives, giant sloths, and saber-toothed marsupial cousins.

The recently analyzed fossil suggests this specimen was far larger than its relatives, which have been estimated to range from 1 to 3 meters (3 and 9 feet) in height.

It also bears signs of how this fearsome predator likely met its end – in the jaws of an even more terrifying beast.
