The aurochs was a large wild bull and the ancestor of domestic cows. This powerful animal lived in the forests and meadows of Europe, Asia, and North Africa until the 17th century.
Aurochs were distinguished by their enormous strength, large horns, and dark coloration of males. They are important to nature as ancestors of domestic cows and large herbivores that maintained the diversity of meadows and forests.
