Archaeologists recovered the first anchor from what is believed to be the wreck of the pirate Blackbeard's flagship off the North Carolina coast, a move that might change plans about how to save the rest of the almost 300 year old artifacts from the ship. The anchor is 11 feet, 4 inches long with arms that are 7 feet, 7 inches across. It was covered with concretion - a mixture of shells, sand and other debris attracted by the leaching wrought iron - and a few sea squirts. Its weight was estimated at 2,500 to 3,000 pounds
