“Lost” Amazon Complex Found; Shapes Seen by Satellite

Posted by Anonymous on January 7, 2010

Hundreds of circles, squares, and other geometric shapes once hidden by forest hint at a previously unknown ancient society that flourished in the Amazon, a new study says. Satellite images of the upper Amazon Basin taken since 1999 have revealed more than 200 geometric earthworks spanning a distance greater than 155 miles (250 kilometers).

Now researchers estimate that nearly ten times as many such structures—of unknown purpose—may exist undetected under the Amazon’s forest cover.

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.

“We found that this picture is wrong,” Schaan said. “And there is a lot more to discover in these places.”

Wide-reaching Culture

The newfound shapes are created by a series of trenches about 36 feet (11 meters) wide and several feet deep, with adjacent banks up to 3 feet (1 meter) tall. Straight roads connect many of the earthworks. Preliminary excavations at one of the sites in 2008 revealed that some of the earthworks were surrounded by low mounds containing domestic ceramics, charcoal, grinding-stone fragments, and other evidence of habitation.

But who built the structures and what functions they served remains a mystery. Ideas range from defensive buildings to ceremonial centers and homes, the study authors say. Hundreds of circles, squares, and other geometric shapes once hidden by forest hint at a previously unknown ancient society that flourished in the Amazon, a new study says.

And it only took, to discover this culture that is now extinct, some deforestation which may make our culture extinct.
