Some Jubba images are difficult to interpret. This large equid, E. asinus or E. hemionus, appears to have a nose ring attached. If this is the case, the image could be as early as the late fourth millennium B.C. Domesticated equids in the Sinai, the Levant, and Mesopotamia were initially controlled by the use of nose rings, baskets, and later by rope bits. Alternatively, the artist may have intended to depict a throw stick striking the (wild) hunted equid. At other Jubba locales, depicted wild camels suggest that they too were part of the natural landscape in the Early Holocene.
