Mesoweb Features

Several representations of fishes like this have been found. It is not improbable that they once were strung to form a fish necklace, with each individual bead/fish hanging from its mouth. Whether these were just naturalistic renderings or had ritual meaning (fish were often associated with the Underworld) is difficult to ascertain without more context information.
