Urus

The aurochs or urus is an extinct, very large type of cattle originally prevalent in Europe. The animal's original scientific name, Bos primigenius, was meant as a Latin translation of the German term Auerochse or Urochs, which was (possibly incorrectly) interpreted as literally meaning "primeval ox" or "proto-ox".
