Elasmotherium, the "Thin Plate Beast," is a prehistoric mammal from a time when everything seemed to grow larger and hairier. With a length of about four and a half meters and a height of over two meters, the Elasmotherium was not an incredibly large creature, but its large horn and power compensated for it. Its meter-tall horn was made of keratin, the substance that makes up human nails, and was probably used for defense and display. Though it weighed almost twice the weight of a white rhinoceros, the Elasmotherium is thought to have been able to gallop just like its modern relative. Living during the late Pliocene to the late Plesitocene, it roamed Eurasia grazing on grass and sometimes browsing selectively to find the most nutritious plants. It likely inhabited savannas, areas with brush, and closed forests. Legends across Asia refer to a beast with a large horn, and some ancient art depicts a creature resembling the Elasmotherium. In Western Europe, tales and Paleolithic art speak of large, horned beasts. If these beasts are Elasmotherium, then their range actually consisted of Western Europe in addition to Eurasia. These legends only add to the mystery of these creatures that science is still working to solve.
