It was roughly the size of a modern rhinoceros but had a distinctive appearance with two large, flattened horns on its head, similar to those of a modern rhino but facing backward.
These horns, along with its massive body, made Arsinoitherium a formidable herbivore.
It likely fed on plants and vegetation in the ancient forests and grasslands of Africa, where its fossils have been found.
