Aerial surveys have revealed the largest pre-colonial cities in the Amazon yet discovered, linked by an extensive network of roads.
“The settlements are much bigger than others in the Amazon,” says Stéphen Rostain at the French National Center for Scientific Research in Paris. “They are comparable with Maya sites.”
What’s more, at between 3000 and 1500 years old, these cities are also older than other pre-Columbian ones discovered in the Amazon. Why the people who built them disappeared isn’t clear.
It is often assumed that the Amazon rainforest was largely untouched by humans before the Italian explorer Christopher Columbus reached the Americas in the 15th century. In fact, the first Europeans reported seeing many farms and towns in the region.
These reports, long dismissed, have in recent decades been backed up by discoveries of ancient earthworks and extensive dark soils created by farmers. One estimate puts the pre-Columbian population of the Amazon as high as 8 million.

No polished stones, no hatchets, much less an archaeological site. Imposing buildings may have been built with advanced technologies. It is a legacy of the MURIL Civilization for humanity
São Paulo, Brasil --News Direct-- 500NewsWire
São Paulo, Brasil, Dec. 22, 2023 - (500NewsWire) -- Humanity's greatest secret may have been revealed by the Dakila Research team with the identification of gigantic constructions in various parts of the Amazon region. After intense fieldwork carried out over 30 years, scholars defined the main area to deepen research in a portion of the territory of the municipality of Apiacás/MT, which became known as “Quadras de Ratanabá”, as it presents characteristics consistent with the existence of ancient civilizations. For this purpose, LiDAR – Light Detection and Ranging – was used mainly for the equipment that, based on light detection, allows the generation of a digital model of the Earth's surface, characterizing structures and vegetation. Analysis of these results shows very peculiar shapes in the relief that were not sculpted by natural forces.
At this location in Apiacás, streets measuring 60, 70 and up to 90 meters in width and up to 27 km in length were identified, partly covered by sediments left by the last deluge. The courts measure 450 meters wide by 650 meters long and are symmetrically perfect. All measurements were made using LiDAR technology and the GPS device used in the field.
Inside the blocks, the staggered formation covered by soil and vegetation can be clearly observed. It is, without a doubt, the greatest find that humanity has ever had access to. At the end of a few blocks, there are fountains of water that appear unexpectedly and, in a few meters, disappear into the ground, as if they were entering a sinkhole.
Next, a GPR – Ground Penetrating Radar or Geo Radar – was used, which uses high-frequency magnetic waves to locate objects and structures under the ground. Exactly where the water disappears, galleries fifteen meters wide by four meters high and more than a kilometer long were identified, in addition to other neighboring galleries, indicating that the water was channeled into the galleries.

Scientists found evidence of 6,000 mounds thought to be the basis for ancient homes
A huge ancient city has been found in the Amazon, hidden for thousands of years by lush vegetation.
The discovery changes what we know about the history of people living in the Amazon.
The houses and plazas in the Upano area in eastern Ecuador were connected by an astounding network of roads and canals.
The area lies in the shadow of a volcano that created rich local soils but also may have led to the destruction of the society.
While we knew about cities in the highlands of South America, like Machu Picchu in Peru, it was believed that people only lived nomadically or in tiny settlements in the Amazon.
"This is older than any other site we know in the Amazon. We have a Eurocentric view of civilisation, but this shows we have to change our idea about what is culture and civilisation," says Prof Stephen Rostain, director of investigation at the National Centre for Scientific Research in France, who led the research.

Can't tell you how stunned I am! As one of the people in one of the articles in this thread acknowledged, their whole view of the Americas has always been "Eurocentric!" Well, we never could have known, could we? 
So glad you saw this too at a time it appears really big news groups are finally starting to pay some attention, this week, anyway!
Thank you, so much, Deuxcents. 
I can't totally calm down, yet, from seeing this breakthrough an hour or so ago. I'm completely hooked for the duration. Let's hope they really keep at it until it's completely uncovered!

Archaeologists have uncovered a cluster of lost cities in the Amazon rainforest that was home to at least 10,000 farmers about 2,000 years ago.
A series of earthen mounds and buried roads in Ecuador was first noticed more than two decades ago by archaeologist Stéphen Rostain. But at the time, “I wasn’t sure how it all fit together,” said Rostain, one of the researchers who reported on the finding in the journal Science on Thursday.
Recent mapping by laser-sensor technology revealed those sites to be part of a dense network of settlements and connecting roadways, tucked into the forested foothills of the Andes, that lasted about 1,000 years.
“It was a lost valley of cities,” said Rostain, who directs investigations at France’s National Center for Scientific Research. “It’s incredible.”
The settlements were occupied by the Upano people between about 500BC and AD300 to 600 – a period roughly contemporaneous with the Roman empire in Europe, the researchers found.
Residential and ceremonial buildings erected on more than 6,000 earthen mounds were surrounded by agricultural fields with drainage canals. The largest roads were 33 feet (10 meters) wide and stretched for 6-12 miles (10-20km).

If you let it get to you, you could end up throwing your laptop(s) through the window, across the room, down the stairs, into the street repeatedly.
None as blind as those who insist they know everything already....
As you've probably heard, read, etc., the ancient structures were also made of much stronger material in the larger communities. They probably hadn't deteriorated to the point they were cutting corners to make quick profits! Maybe they were sensible enough to know everyone suffers if people aren't honest about their behavior and relationships at all levels.
Started reading and hearing years ago that early archaeologists in the Amazon in Brazil were finding, in the settlements they were discovering, that it was common for the people who grew food to amend the soil with large amounts of charcoal as a part of their natural agriculture, and that they developed incredibly productive, rich soil around the inhabited areas which have been covered by jungles through the centuries.
At the time I was hearing about the Brazilian Amazon discoveries, I had absolutely no idea they would also be uncovering civilization in the older Ecuador.
Maybe the "Eurocentric" archaeology community is going to be taken to school!
Thank you, Warpy.

(I'll bet the people who lived there didn't know they were living in a lost valley of cities!)
Aerial surveys have revealed the largest 2,500-year-old ancient cities in the Amazon, hidden for thousands of years by lush vegetation and connected by an extensive road network.
The Amazon rainforest was once home to ancient cities, confirms ‘Science’ magazine, which has published a description of Ecuador’s largest and oldest known Amazonian settlement.
An international study published on Thursday, January 11, in Science, reveals a network of garden cities along the Upano River in Ecuador, dating back to 500 BC. It’s the oldest and largest urban network in Amazonia.
It is often assumed that the Amazon rainforest was largely untouched by humans before the Italian explorer Christopher Columbus reached the Americas in the 15th century.
However, the first Europeans reported seeing many farms and towns in the region. Francisco de Orellana, a Spaniard, set out from the eastern foothills of the Ecuadorian Andes at the end of 1541 with a few dozen men, embarking on an amazing river journey that would take them from west to east across the entire continent of South America, ending in the Atlantic Ocean via the Amazon River. Gaspar de Carvajal, a Dominican national, wrote about the dangerous 10-month expedition in which he was ambushed by an Indigenous tribesperson and lost an eye due to an arrow.

Archaeologists once believed the ancient Amazon rainforest was an inhospitable place, sparsely populated by bands of hunter-gatherers. But the remains of enormous earthworks, pyramids, and roads from Bolivia to Brazil discovered over the past 2 decades have proved conclusively that the Amazon was home to large, complex societies long before European colonizers arrived. Now, there’s evidence that another human society—the oldest yet—left its mark on the region: A dense network of interconnected cities, now hidden beneath the forest in Ecuador’s Upano Valley, has been revealed by the laser mapping technology called lidar. The settlements, described today in Science, are at least 2500 years old, more than 1000 years older than any other known complex Amazonian society.
Lidar, which allows researchers to see through forest cover and reconstruct the ancient sites below, “is revolutionizing our understanding of the Amazon in pre-Columbian times,” says Carla Jaimes Betancourt, an archaeologist at the University of Bonn who wasn’t involved in the new work. Finding such an ancient urban network in the Upano Valley highlights the long-unrecognized diversity of ancient Amazonian cultures, which archaeologists are just beginning to be able to reconstruct.
Stéphen Rostain, an archaeologist at CNRS, France’s national research agency, began excavating in the Upano Valley nearly 30 years ago. His team focused on two large settlements, called Sangay and Kilamope, and found mounds organized around central plazas, pottery decorated with paint and incised lines, and large jugs holding the remains of the traditional maize beer chicha. Radiocarbon dates showed the Upano sites were occupied from around 500 B.C.E. to between 300 C.E. and 600 C.E. “I knew that we had a lot of mounds, a lot of structures,” Rostain says. “But I didn’t have a complete overview of the region.”
That changed when Ecuador’s National Institute for Cultural Heritage funded a lidar survey of the valley in 2015. Specially equipped planes beamed laser pulses into the forest and measured their return path, revealing topographic features otherwise invisible under the trees.
