16.5" Sub-Adult Titanothere (Megacerops) Mandible - South Dakota

Sub-Adult Titanothere (Megacerops) Mandible - South Dakota #249234

This is a 16.5" long mandible (lower jaw) of the massive titanothere, Megacerops, a Rhinoceros-looking animal that lived during the Late Eocene. It was collected from the Eocene-aged Chadron Formation of South Dakota. It is the right side of the jaw and still contains three erupted teeth and two unerupted teeth, for a total of five complete, beautifully preserved teeth.

Restoration is pretty minimal on this jaw, making up approximately 2% of the specimen. This restoration can be found along the interior side of the jaw as gap fill.

Comes with an acrylic-metal display stand.

Titanotheres have been described under various genera (Brontotherium, Titanotherium, BrontopsMegacerops was the first and therefore technically correct one.
