TITUSVILLE, FLORIDA—A pond in eastern Florida that held prehistoric burials dating to more than 8,000 years ago has been bought by the Archaeological Conservancy for $90,000—effectively saving it from being destroyed to make way for a new housing development. In 1982 construction near Windover Pond inadvertantly led to the discovery of more than 150 early Archaic burials, including 91 skulls with brain tissue still intact in them. Excavations in the mid-1980s also uncovered ancient textiles and a 15-year-old boy who apparently died of spina bifida. "Windover is an extremely significant and important site. It's unique," said Jessica Crawford, the Archaeological Conservancy's Southeast regional director. "We'll do what we need to do to keep it protected and keep it intact."
