Analysis of hull remains of the Dor D Vessel, Tantura Lagoon, Israel

A relatively closely spaced set of unpegged mortise-and-tenon joints was the significant element revealed in the 7th-century AD shipwreck, Dor D. It provides additional information for the transitional period of shipbuilding in the Mediterranean, and together with additional wrecks it establishes a better database for ship construction in the 4th-11th centuries AD. The preliminary conclusions tend to draw a slightly more complicated picture of the general evolutionary trend, since they present some features that have traditionally been considered as a disappearing technique.
