Thank goodness it's #fossilfriday! Gomphotherium, pictured, lived 10 million years ago and is a member of the order Proboscidea, which includes elephants and their relatives. Like this gomphothere, they all have enlarged incisor teeth, called tusks. Find gomphotherium in the Hall of Primitive Mammals. #amnh
