Diplasiotherium is an extinct genus of litoptern belonging to the family Proterotheriidae, that lived between the late Miocene and the early Pliocene (in the SALMAs Huayquerian and Montehermosan). [1] The fossils of this animal have been found in Argentina, in the Monte Hermoso Formation. [2] [3]
Diplasiotherium is distinguished from other proterotheriids by the crown of its molars, which were higher than in other related genera (protohypsodont), and by its larger body size; the species D. robustum reached approximately 395 kilograms (871 lb) in weight, making it the largest known proterotheriid.
