Overview of the Bourdois Shelter, Roc-aux-Sorcier. Two registers of wall sculptures show, in the upper part, a herd of males and, in the lower section, a troop of female ibex and their young. The composition and the organisation of this troop is reminiscent of when animals gather at the start of winter.

The Magdalenians thus transferred to the wall their knowledge of the ethology of the ibex.
