Scientists have discovered centuries-old lost cities in the Amazon jungle. Archaeologist Stephen Rostein discovered buried roads and mud mounds in the South American country of Ecuador two decades ago, but at the time he was not convinced of his discovery.
In a study published in the journal Science, Stephen Rostein and other experts mapped the region using laser sensor technology.
This map shows that some once-crowded settlements and roads led to the foothills of the Andes Mountains.
According to Stephen Rostein, this is a lost valley of cities, and the discovery is surprising. The region was occupied by the Upano tribe in 500 BC, and they lived there from 300 to 600 AD.
During the research, residential and religious buildings in the region were excavated from the mud mounds. The buildings were surrounded by fields and a system of canals, while the longest roads were 33 feet wide and 6 to 12 miles long.
By the way, it is difficult to estimate the population of this region, but according to experts, at least 10 thousand people live there. According to experts, the research proves that these were very crowded cities, and the societies here were quite complex.
He further said that the people living in the Amazon did not have stones to build buildings, so they built buildings with mud. It was long believed that few people lived in the Amazon jungle, but recent research reports have shown that the region's past is more complex than previously thought.
The results of this research were published in the journal Science.
