Experts have provided the grisly goods to back up 17th-century accounts of cannibalism during the Jamestown colony's "starving time" — including a skull that shows signs of being chopped at and pried apart. "Our team has discovered partial human remains before, but the location of the discovery, visible damage to the skull and marks on the bones immediately made us realize this finding was unusual," Bill Kelso, chief archaeologist of the Jamestown Rediscovery Project in Virginia, said in a news release issued Wednesday. Specimens from the Jamestown site were laid out during a Washington news conference.
