A University of Colorado at Boulder team excavating an ancient Maya village in El Salvador buried by a volcanic eruption 1,400 years ago has discovered an ancient field of manioc, the first evidence for cultivation of the calorie-rich tuber in the New World.
The manioc field was discovered under roughly 10 feet of ash, said CU-Boulder anthropology Professor Payson Sheets, who has been directing the excavation of the ancient village of Ceren since its discovery in 1978. Considered the best-preserved ancient village in Latin America, Ceren's buildings, artifacts and landscape were frozen in time by the sudden eruption of the nearby Loma Caldera volcano about 600 A.D., providing a unique window on the everyday lives of prehistoric Mayan farmers.
The discovery marks the first time manioc cultivation has been discovered at an archaeological site anywhere in the Americas, said Sheets. The National Geographic Society funded the 2007 CU-Boulder research effort at Ceren, the most recent of five research grants made by NGS to the ongoing excavations by Sheets and his students.
