Review: Arsinoitherium (Prehistoric Life Collection by Safari Ltd)
4 (22 votes)
Arsinoitherium was a large paenungulate mammal which lived roughly 30 million years ago during the late Eocene and early Oligocene epochs in Northeastern Africa. These animals would have superficially resembled modern rhinoceroses but were in fact more closely related to elephants. Unlike those of a rhinoceros, the massive horns of Arsinoitherium were comprised of solid bone.
