Lost Amazon complex found

At least one of the sites has been dated to around A.D. 1283, although others may date as far back as A.D. 200 to 300, said study co-author Denise Schaan, an anthropologist at the Federal University of Pará in Belém, Brazil.
The discovery adds to evidence that the hinterlands of the Amazon once teemed with complex societies, which were largely wiped out by diseases brought to South America by European colonists in the 15th and 16th centuries, Schaan said.
Since these vanished societies had gone unrecorded, previous research had suggested that soils in the upper Amazon were too poor to support the extensive agriculture needed for such large, permanent settlements.
