Fig. 2: Steppe rhino cranium associated with a hammerstone.

Detail of the process of excavation of Level 3 in square J′40, where a Stephanorhinus hemitoechus cranium (16/12/CDC/J′40/101.2/691) was found (face down). The photographed surface is approximately horizontal. The black arrow points north. The cranium lacks maxillae. Just above the cranium, there is a rounded granite boulder (16/12/CDC/J′40/101.2/600) with a battered area, indicating its use as a hammerstone. Note the bison horn core just above the rhino cranium and the remains of a large bovid cranium to the right (see Supplementary Fig. 25 for a diagram highlighting the important elements in the picture).
