18.7" Fossil Titanothere (Megacerops) Jaw - South Dakota

Fossil Titanothere (Megacerops) Jaw - South Dakota #227757

This is a 18.7" long jaw of a massive Titanothere, a Rhinoceros-looking animal that lived during the Late Eocene. It was collected from the Eocene aged Chadron Formation of South Dakota. There are four original molars present in the jaw.

Restoration is pretty minimal on this jaw. There is some restoration along the "gum line" below the teeth and on coronoid process.

Comes with a display stand.
