Synonyms

Prohegetotherium is an extinct genus of hegetotheriid notoungulates from the Late Oligocene to Early Miocene (Deseadan-Santacrucian in the SALMA classification) of the Agua de la Piedra,[1] Mariño & Sarmiento Formations of Argentina, the Petaca and Salla Formations of Bolivia, and Fray Bentos Formation of Uruguay.[2][3]

Taxonomy

Prohegetotherium comprises three species, P. sculptum, P. schiaffinoi, and P. malalhuense.[2] Although Prohegetotherium shumwayi and P. crassus have long been synonymized with P. sculptum, Kramarz and Bond (2017) restricted P. sculptum to the holotype, rejecting the synonymy.[4]
