English: Megabelodon lulli Barbour, 1914 - fossil elephant skeleton from the Miocene of Nebraska, USA. (public display, Nebraska State Museum of Natural History, Lincoln, Nebraska, USA)
This remarkable fossil elephant had an extremely elongated, downcurved, tuskless lower jaw.
From museum signage:
"All known skeletons of this "four tusker" were found in the Nebraska Niobrara River Valley. Mysteriously, all of them lack the tusks in the lower jaw. Instead of having lower tusks, these elephants may have had a flexible lower lip."
Classification: Animalia, Chordata, Vertebrata, Mammalia, Placentalia, Proboscidea, Gomphotheriidae
