 Present @-@ day knowledge of the original materials and methods used in construction of this particular Arab dhow stems largely from the shipwreck itself . The Jewel of Muscat reconstruction , a replica made as an exact copy of the wreck , has shown that the ship resembles a <unk> <unk> , a type of ship still found in Oman today . Amongst the hull of the shipwreck were large lumps of concretion containing artefacts from the ship 's cargo dated to the Tang dynasty of China around 800 AD , and from where the wreck gets its other names , the " Tang shipwreck " or " Tang treasure ship " .
