These fish salting amphoras were made in the High and in the Medium period of the Roman Empire in Baetica. Within the classification/typology shown in the picture, it approaches its variant B type Beltran IIB , although some authors state that it is a new type called Puerto Real 1A, because its edge does not normally mark the transition to the neck, while it tends to rest directly on the top of the handle; these features lead us to consider them the later ones within their group (later in the second century AD).
Still, a lack of excavations of coastal potteries in Baetica, between the final moments of the first century AD and the second century AD, it does not allow to refine in the variant, because of the multitude of forms identified in Southern Hispania. Trade in these was located in the coastal cities of the Western Mediterranean.
This piece was found in the environs of the Strait of Gibraltar, in the waters of Tarifa.
