Elephant tusk evolution, artwork. These three species from the elephant evolutionary tree are: Moeritherium (top), Gomphotherium (centre) and Mammuthus (the mammoth, bottom). The artworks show the skulls, and how the tusks evolved from the incisors (front teeth). Moeritherium existed during the Eocene (55 to 38 million years ago) and had elongated incisors. Gomphotherium existed in the Oligocene (38 to 24 million years ago) and had both upper and lower tusks. The mammoths existed in the Pliocene and Pleistocene (5 million to 10,000 years ago) and only had upper tusks.
