This bison has been painted and carved and it makes use of the edges and cracks of the rock. The animal has in fact been created using features of the rock, which have been completed.
The upper edge of the stratum acts as the back. One joint in the stratum serves as the rump and the base of one of the back legs.
Other cracks complete the leg to the front and mark the line of the thigh in the abdomen. Another joint marks the scapular area and the base of the front leg. Between the front and back legs the line of the abdomen has been drawn.
