The Magdalenian sculptors respected proportions and anatomical details, and translated their knowledge of the animal world. Many details are included, such horns, eyes and tongues, which render the subjects even more realistic.

At Roc-aux-Sorciers, for example, a male ibex is shown sticking out its tongue, the eyes of the horses and ibex are very detailed, and we can clearly distinguish the eyelid and lacrimal caruncle. One can also make out the anatomical detail of the limbs of bison and ibex – including tendons, muscle and joints – down to their cloven hoofs and the detail of the soft flesh at the base of the hoof known as the bulb.

At Chaire-à-Calvin, the eye of the horse is treated the same way as the one at Roc-aux-Sorciers.

At Cap Blanc, the details are less accurate because the artists' attention focused on the volumes.
