Behaviour and ecology

Aurochs formed small herds mainly in winter, but typically lived singly or in smaller groups during the summer. If aurochs had social behaviour similar to their descendants, social status would have been gained through displays and fights, in which both cows and bulls engaged. Since it has a hypsodont jaw, it has been suggested to have been a grazer, with a food selection very similar to domesticated cattle feeding on grass, twigs and acorns. Mesowear analysis of Holocene Danish aurochs premolar teeth indicates that it changed from an abrasion -dominated grazer in the Danish Preboreal to a mixed feeder in the Boreal, Atlantic and Subboreal periods. Dental microwear and mesowear analysis of specimens from the Pleistocene of Britain has found these aurochs had mixed feeding to browsing diets, rather than being strict grazers.
