Erosion on the seabed of the English Channel near the Isle of Wight is uncovering the remains of a thriving Stone Age village from the time when Britain and Europe were still connected by a land bridge, a team of archaeologists reports.

The site dates back 8,000 years, not long before melting glaciers filled in the Channel and likely drove the settlement's last occupants north to higher ground.

"This is the only site of its kind in the United Kingdom," said Garry Momber, director of the Hampshire and Wight Trust for Maritime Archaeology, which led the recent excavations. "It is important because this is the period when modern people were blossoming, just coming out of the end of the Ice Age, living more like we do today in the valleys and lowlands."

Burnt wood fragments gouged with cut marks and a layer of wood chippings were found lying under 35 feet of water during the latest dig. Divers brought the material to the surface still embedded in slabs of the sea floor that were carried up in specially-designed boxes, which were then pieced back together and examined and dated in the lab.

"We now have unequivocal evidence of human activity at the site," Momber told LiveScience. "There were people here actively making stuff and being quite industrious."

Despite the logistical problems of underwater archaeology, the Isle of Wight site and others like it are usually better preserved than their counterparts on land, Momber said.

When the floodwater rose slowly in the English Channel, it deposited layers of silt atop the settlement, encasing it in an oxygen-free environment that preserves even organic materials such as wood and food.

"With underwater sites, all the trappings of a society are going to remain, not just the stone," Momber said. The trade-off is an environment that can carry away the precious remains at any time — a real concern at the Isle of Wight settlement.
