The exact purpose of these structures however continues to remain a matter of some debate.

A lack of artefacts at the sites makes it unlikely that they were used for habitation and their layout suggests that they were not designed to be defensive structures either.The most likely explanation is that they were some sort of ritual sites.

"The fact that these sites lay hidden for centuries beneath mature rainforest really challenges the idea that Amazonian forests are 'pristine ecosystems'," said researcher Jennifer Watling.

"We immediately wanted to know whether the region was already forested when the geoglyphs were built, and to what extent people impacted the landscape to build these earthworks."
