Kelenken is an extinct genus of giant flightless predatory birds of the family Phorusrhacidae or "terror birds". These birds lived in the Middle Miocene, some 15 million years ago, in Argentina along with Argentavis. With a skull 28 inches (71 cm) long (including its 18 inch, 45.7 cm beak), it had the largest head of any known bird.

Size

Kelenken was one of the largest carnivorous birds of all time, possibly reaching 2.28 to 3 meters (7.5 to 10 feet) tall and weighing around 500 pounds (230 kg).

Diet

It was a large, flightless carnivore which probably chased down and killed its prey with several bone-shattering blows from its beak. Another possibility is that it may have picked up its prey item, then proceeded to shake it vigorously to break its back, or simply deliver a fatal bite from its massive beak.

In Pop Culture

  • Kelenken appears in Prehistoric Predators.
  • It also appears in Jurassic Park: Builder.
