An ancient tomb uncovered by construction workers in Yangpu District last Friday contains the remains of someone who lived during the Ming Dynasty (1368-1644), local archaeologists announced yesterday.

Two archaeologists, with the help of several construction workers, yesterday opened one of two coffins found at the site, unearthing a body covered by four shrouds and about 13 belts.

"It is one of the best preserved bodies from the Ming Dynasty ever found in Yangpu District, particularly its skeleton," said He Jiying, an archaeologist with the Shanghai Cultural Relics Management Commission who worked on the site.

She said she is certain the tomb was made during the Ming Dynasty because the coffins were covered by two large stone boards - a typical way of arranging tombs during that period.

Scientists still haven't taken a good look at all the contents of the coffin, which is filled with water and mud. It will take two to three days to work out the detailed features of the tomb.

The tomb was found accidentally by workers in the Yangpu Dushi Industrial Park on Yinhang Road last Friday.

"I assumed the site was an ancient tomb because it was much harder than normal underground, which is mainly made of soft earth," said Wang Jiding, a construction manager on the project.
