The villa at Dinnington was excavated by Prof. Tony King and post-excavation work is ongoing. Analysis of the pottery shows that Type 18 vessels were present in nine contexts for a total of 12 sherds (weighing 0.840kg) (personal observation). In two contexts the Type 18 vessels were associated with coins of the House of Valentinian (AD 364-378). These coins were common at Dinnington and the later Theodosian issues were much rarer. Nevertheless, the site was probably occupied into the 5th century, with 5th-century radiocarbon dates returned from some late features (Prof. Tony King pers. comm.). Once the analysis of the excavation archive is complete it is possible that more light will be shed on the chronology of the Type 18 vessels.
