NEW YORK: Workers excavating at the World Trade Center site have unearthed the 32-foot hull of a ship likely buried in the 18th century.

The vessel probably was used along with other debris to fill in land to extend lower Manhattan into the Hudson River, archeologists said. Archeologists Molly McDonald and A Michael Pappalardo were at the site of the Sept. 11, 2001, terror attacks on Tuesday morning when workers uncovered the artifacts.

"We noticed curved timbers that a backhoe brought up," McDonald said. "We quickly found the rib of a vessel and continued to clear it away and expose the hull over the last two days."
