These bison were prominently positioned at the centre of a small, difficult to reach chamber deep in the cave system of Tuc d’Audoubert. Made from unbaked clay, the composition depicts the larger bull positioned behind a cow. Their bodies were moulded by hand and still show finger marks. The details of the heads and necks were carved or incised using tools. The tail of the cow, now broken off, was raised ready for mating. European bison mate in September just before the onset of winter. Did the sculptures mark a visit or ceremony at this time of year?
