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.[1][4]
