EL SOTO, BOLIVIA—Human remains dated to 1,100 years ago have been unearthed at a Tupi-Guarani culture archaeological site in eastern Bolivia, according to a report in Telesur, based upon reporting from the local newspaper, El Deber. The skeleton is thought to have belonged to a young woman who had been buried lying curled on her side. Archaeologist Danilo Drakic explained that the site, discovered by schoolchildren who were planting a garden, was a trade center for people living as far away as the regions that are now Brazil, Paraguay, and Argentina. Pottery, shells, and lapis stones imported from Chile have also been recovered. For more on archaeology in South America, go to "An Overlooked Inca Wonder."
