Prohegetotherium

Prohegetotherium is an extinct genus of hegetotheriid notoungulates from the Late Oligocene to Early Miocene of the Agua [de la Piedra Formation|Agua de la Piedra], Mariño & Sarmiento Formations of Argentina, the Petaca and Salla Formations of Bolivia, and Fray [Bentos Formation] of Uruguay.

Taxonomy

Prohegetotherium comprises three species, P. sculptum, P. schiaffinoi, and P. malalhuense. Although Prohegetotherium shumwayi and P. crassus have long been synonymized with P. sculptum, Kramarz and Bond restricted P. sculptum to the holotype, rejecting the synonymy.
