SAO PAULO, Brazil - A grouping of granite blocks along a grassy Amazon hilltop may be the vestiges of a centuries-old astronomical observatory — a find that archaeologists say shows early rainforest inhabitants were more sophisticated than previously believed. snip...

RIO DE JANEIRO (AFP) - Archaeologists discovered a pre-colonial astrological observatory possibly 2,000 years old in the Amazon basin near French Guiana, said a report. "Only a society with a complex culture could have built such a monument," archaeologist Mariana Petry Cabral, of the Amapa Institute of Scientific and Technological Research (IEPA), told O Globo newspaper. The observatory was built of 127 blocks of granite each three meters (10 feet) high and regularly placed in circles in an open field, she said. Cabral said the site resembles a temple which could have been used as an observatory, because the blocks...

Brazilian archaeologists have found an ancient stone structure in a remote corner of the Amazon that may cast new light on the region's past. The site, thought to be an observatory or place of worship, pre-dates European colonisation and is said to suggest a sophisticated knowledge of astronomy. Its appearance is being compared to the English site of Stonehenge. It was traditionally thought that before European colonisation, the Amazon had no advanced societies. Winter solstice The archaeologists made the discovery in the state of Amapa, in the far north of Brazil. A total of 127 large blocks of stone were...

ST. LOUIS -- The search for El Dorado in the Amazonian rainforest might not have yielded pots of gold, but it has led to unearthing a different type of gold mine: some of the globe's richest soil that can transform poor soil into highly fertile ground. That's not all. Scientists have a method to reproduce this soil -- known as terra preta, or Amazonian dark earths -- and say it can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming. That's because terra preta is loaded with...

Bird’s-Eye View of the Amazon Airborne Archaeologist Challenges the Myth of a Pristine Wilderness by Ted Mann In the office of a typical archaeologist, you would expect to find things like stone tools, pottery fragments, and maybe even a few Wooly Mammoth bones. But Clark Erickson is no typical archaeologist. Oversize rolls of aerial photographs are stacked into tubular pyramids on a desk and worktable in his University Museum office. They fill up file cabinets and populate a storage room. At last count, he had about 700 giant aerial and satellite images—almost all of them picturing some region of the...

Amazonian find stuns researchers Deep in the Amazon forest of Brazil, archaeologists have found a network of 1,000-year-old towns and villages that refutes two long-held notions: that the pre-Columbian tropical rain forest was a pristine environment that had not been altered by humans, and that the rain forest could not support a complex, sophisticated society. A 15-mile-square region at the headwaters of the Xingu River contains at least 19 villages that are sited at regular intervals and share the same circular design. The villages are connected by a system of broad, parallel highways, Florida researchers reported in yesterday's issue of...

Suddenly, the remains of larger squash plants appear in the record. The Las Vegas site, described by Dolores Piperno of the Smithsonian Tropical Research Institute (STRI) and Karen Stothert, University of Texas at Austin in the February 14th issue of Science, may predate plant domestication sites in the Mesoamerican highlands. The fertile and amazingly diverse lowland tropics seem like a likely place for agriculture to develop. But...

DISCOVER Vol. 23 No. 5 (May 2002)Table of Contents The Amazon Trail Anna Roosevelt's ventures into the jungles of South America have turned up traces of human settlements far older than archaeologists ever suspected By John Dorfman Photography by Jennifer Tzar Archaeologists visiting remote sites in Brazil must rely on the skills of local pilots to locate—and land on—small airstrips in the rain forest. "The pilots here are very good," says Roosevelt, a veteran Amazon explorer, because the mining industry depends on them. "When I have a goal," says Anna Curtenius Roosevelt, her voice emphasizing the word, "everything else is...

Genetic analysis of plant species has long pointed to the lowlands of southwest Amazonia as a key region in the early history of plant domestication in the Americas, but systematic archaeological evidence to support this has been rare. The new evidence comes from recently-exposed layers of the Teotonio archaeological site, which has been described by researchers as a "microcosm of human occupation of the Upper Madeira [River]" because it preserves a nearly continuous record of human cultures going back approximately 9,000 years. In this study, Watling and colleagues analyzed the remains of seeds, phytoliths, and other plant materials in the...

Look around the Amazon rainforest today and it’s hard to imagine it filled with people. But in recent decades, archaeologists have started to find evidence that before Columbus’s arrival, the region was dotted with towns and perhaps even cities. The extent of human settlement in the Amazon remains hotly debated, partly because huge swaths of the 6-million-square-kilometer rainforest remain unstudied by archaeologists. Now, researchers have built a model predicting where signs of pre-Columbian agriculture are most likely to be found, a tool they hope will help guide future archaeological work in the region. In many ways, archaeology in the Amazon...

(Jan. 8) – As a result of the deforestation of the Amazon basin, a startling discovery has been made. Hidden from view for centuries, the vast archaeological remains of an unknown, ancient civilization have been found. A study published in Antiquity, a British archaeological journal, details how satellite imagery was used to discern the footprint of the buildings and roads of a settlement, located in what is now Brazil and believed to span a region of more than 150 miles across. "The combination of land cleared of its rain forest for grazing and satellite survey have revealed a sophisticated pre-Columbian...

Henry Ford didn't just want to be a maker of cars — he wanted to be a maker of men. He thought he could perfect society by building model factories and pristine villages to go with them. And he was pretty successful at it in Michigan. But in the jungles of Brazil, he would ultimately be defeated. It was 1927. Ford wanted his own supply of rubber — and he decided to get it by carving a plantation and a miniature Midwest factory town out of the Amazon jungle. It was called "Fordlandia." Leonor Weeks DeCeco was 8 years old...

Deep in the central Amazonian rainforest lies a rich, black soil known locally as terra preta do Indio (Indian dark earth) that farmers have worked for years with minimal fertilization. A Brazilian-American archeological team believed terra preta, which may cover 10 percent of Amazonia, was the product of intense habitation by Amerindian populations who flourished in the area for two millennia, but they recently unearthed evidence that societies lived and farmed in the area up to 11,000 years ago. As...

You'd be hard-pressed to find similarities between the Amazonian jungles of Brazil and the mountains of Afghanistan, but there are some. Air Force Gen. Richard B. Myers, chairman of the Joint Chiefs of Staff, kicked off a trip to South America with a stop here in the capital of Amazonia. During a briefing from Brazilian Maj. Gen. Eduardo Dias da Costa Villa Boas, the commander of army forces in the region, Myers was struck by the similarity of tactics the coalition uses in Afghanistan and tactics the Brazilian government is using in this far-flung region of the country. The Brazilian...
