Monuments discovered in Amazon
Now researchers estimate that in this pond of unknown can be detected ten times more of these structures.
One of these images, according to researcher, dating to around 1283 AD, although others may date back as far back period to 200 and 300 years after Christ, so declares an anthropologist at the Belém UniversitetinFederal Para, Brazil.
Schaan said the discovery strengthens the evidence that the periphery of the Amazon River was full of complex society.
These companies that are located in the upper Amazon, for reasons not favorable land to develop a strong agriculture, has forced those who do not become major centers of permanent residence.
"We discovered that this idea is not wrong," Schaan said. "And there's much more to discover in these countries."Forms found as trenches about 12 feet wide, with several feet deep, surrounded by about 1 meter high in the right way to connect many of these working places, to open space for further study.
Preliminary excavations of sites in a plateau in 2008 zbulan that some ancient structural working places, surrounded by concentric circles of low përmbajnin ceramics, charcoal, fragments of stone, and other evidence of the country.
But who built these structures and what their functions, remains a mystery. It is thought that the buildings served as defensive center and houses as ceremonial sites, so say the authors of the study.
It is also possible to have structures that serve different purposes over time, said
William Woods, a geographer and anthropologist at the University of Kansas in Lawrence, who was involved in research.
It's what the research team was surprised that circles it seems to work were as flood plains, as well as in the mountains.
In general, fertile Lowland Amazon has been populated with ancient civilizations, and plateaus have been less populated, say researchers.
In addition, field operations in both regions are similar in style, suggesting that they were built by the same company.
"" The archeology of the Amazon is always the idea that these were different people in different ecosystems, "said a study co-author of Schaan.
"And so it was strange that tegjeje a culture that had possessed different ecosystems, in a large area."
It seems that in the mountain sites have resided in their homes for over 60,000 people, declare Schaan and his colleagues in their article, published this month in the journal
This figure is based on assessments of social organization and the work that was done to build structures imaginable, based on the remaining earthworks.
According to Woods, the population estimate is rough, because very few are known these complex societies.
Researchers will continue to dig the format found in the coming years.
Woods, however, claims it as impossible that so many people have lived so long on these plateaus upper Amazon.
If such a question has traditional will make an anthropologist or an archaeologist, the answer from them .. zero .. sibilities was life in those areas therefore seems unlikely.
"And so it is surprising to know that there are over 60,000 people live"
