This illustration shows a paleoartist's reconstruction of the three extinct rhinoceros species whose genomes were sequenced as part of the study. In the foreground is a Siberian unicorn (Elasmotherium sibiricum), and close behind are two Merck’s rhinoceroses (Stephanorhinus kirchbergensis). In the far background is a woolly rhinoceros (Coelodonta antiquitatis).
