Polychrome bison, forming part of a frieze. The natural contours of the rock were used to implement this figure, which includes a very marked outline in red-brown highlighted with a line etched directly onto the exposed substrate. The body of the animal now seems much lighter than it would have been originally. For this part of the cave and in particular this representation there is no trace of concretions covering the pigments. It may be that the pigments have eroded from the surface.
