the biblical 'unicorn'?
Elasmotherium is an extinct genus of large rhinoceros endemic to Eurasia during Late Miocene through the Pleistocene, existing at least as late as 39,000 years ago in the Late Pleistocene.[2] A more recent date of 26,000 BP is considered less reliable.[2] It was the last surviving member of Elasmotheriinae, a distinctive group of rhinoceroses separate from the group that contains living rhinoceros (Rhinocerotinae). The two groups are estimated to have split at least 35 million years ago according to fossils and molecular evidence.
Five species are recognised. The genus first appeared in the Late Miocene in China, likely having evolved from Sinotherium, before spreading to the Pontic–Caspian steppe, the Caucasus and Central Asia.[3] The best known, E. sibiricum, sometimes called the Siberian unicorn,[4] was the size of a mammoth and is thought to have borne a large, thick horn on its forehead (though see below). Like all rhinoceroses, elasmotheres were herbivorous. Unlike any other rhinos and any other ungulates aside from some notoungulates, its high-crowned molars were ever-growing, and it was likely adapted for a grazing diet. Its legs were longer than those of other rhinos and were adapted for galloping, giving it a horse-like gait.
