The Kelenken was a species of giant flightless predatory birds of the extinct family phorusrhacid, or "terror birds" that lived in the Middle Miocene, some 15 million years ago, in Argentina. It is closely related to the Cariamids. Kelenken was the top predator of its area and hunted other predators too. Kelenken, rather than flying, it ran fast, running up to 35 mph (56.3 kph). With a skull 71.6 cm (28.2 inches) long, it had the largest head of any known bird. It is the largest species of phorusrhacid.
The Kelenken appears as a Glacier Park animal in Jurassic Park: Builder as a gold creature.
