Notiotitanops (Greek for Big face of the South) is a brontothere endemic to North America during the Eocene living from 48.6—37.2 mya, existing for approximately 11.4 million years.[1]

Taxonomy

Notiotitanops was named by Gazin and Sullivan (1942).[2] Its type is Notiotitanops mississippiensis. It was assigned to Titanotheriidae by Gazin and Sullivan (1942); and to Brontotheriidae by Mader (1998).[3]

Morphology

Two specimens were examined by M. Mendoza for body mass The first specimen was estimated to have a weight of 167.1 kg (370 lb). The second was estimated to have a weight of 617 kg (1,400 lb).[4]
