Archaeologists recovered more than 200 precious porcelain artifacts from the cabin of the Nanhai No 1 before the 40-day trial exploration of the shipwreck was wrapped up Sunday.
Chinese experts also found well-preserved wooden parts of the cabin and deck on the merchant vessel, which sunk off the coast of Guangdong province 800 years ago, said project leader Wei Jun.
"The porcelain relics discovered are totally different from those we use today in terms of size and appearance," he said.
Relics recovered this time are believed to have been made in private kilns in Jingdezhen, Jiangxi province, and Dehua, Fujian province, he said.
The Crystal Palace housing Nanhai No 1 at the Marine Silk Road Museum in Yangjiang, Guangdong province.
Nanhai No 1 was built during the Song Dynasty (AD 960-1279) and the recovered porcelain pieces, which were under piles of grass, are expected to prove important sources to archeologists studying shipping during the period.
"The well-preserved vessel has offered more evidence of the existence of an ancient maritime trade route linking China and the West," said Wei.
The deck discovered this time is the only well-preserved example from the era, he added.
