Iranotherium ("Beast of Iran") was a large elasmothere rhinoceros, as big as a modern white rhino, found in the Middle East and Central Asia. It was a precursor of the related Sinotherium, and may have been ultimately outcompeted by its descendant.
Males were larger than the females and had more developed muscle scars on the zygomatic arch.
