Stamp Seal in the Shape of a Recumbent Bull: Two Dogs?

Zoomorphic stamp seal in the shape of a reclining bull with head, horns, and legs clearly represented. The bull's eyes are indicated by drilled holes. The piece is pierced laterally near the base. An incised decoration of two quadrupeds (dogs?) appears on the flat underside. The animals' bodies were created by shallow drill holes and the limbs by incised lines, making taxonomic identification difficult.
