Quickly, excavations on the website within the coastal metropolis of Sao Luis had uncovered hundreds of artifacts left by historic peoples as much as 9,000 years in the past — a treasure trove archaeologists say might rewrite the historical past of human settlement in Brazil.
The lead archaeologist on the dig, Wellington Lage, says he had no thought what he was moving into when Brazilian development large MRV employed his firm, W Lage Arqueologia, in 2019 to hold out an affect research on the website — a part of the routine process of getting ready to construct an residence constructing.
Coated in tropical vegetation and bordered by the city sprawl of Sao Luis, the capital of Maranhao state, the 15-acre plot was often called Rosane’s Farm, for the daughter of a late native landholder.

His crew quickly discovered way more: a flood of stone instruments, ceramic shards, embellished shells and bones.
In 4 years of digging, they’ve unearthed 43 human skeletons and greater than 100,000 artifacts, in keeping with Brazil’s Institute for Nationwide Historic and Inventive Heritage (IPHAN), which introduced the invention final week, calling it “grandiose.”
“Barely scratched the floor”
Researchers now plan to catalogue the artifacts, analyze them intimately, put them on show and publish their findings.
“We have been working 4 years now, and we have barely scratched the floor,” mentioned Lage, a 70-year-old Sao Paulo native whose spouse and two youngsters are additionally archaeologists.
In a video posted to social media by IPHAN, archaeologist will be seen working on the website, sifting by means of bones and artifacts.
“The excavations proceed, indicating the potential for brand new discoveries,” the caption reads. “Unimaginable, proper?”
The preliminary findings are already grabbing consideration within the scientific group.
Lage says his crew — which grew to 27 folks in all, together with archaeologists, chemists, a historian and a documentary filmmaker — has discovered 4 distinct eras of occupation on the website.
The highest layer was left by the Tupinamba folks, who inhabited the area when European colonizers based Sao Luis in 1612.
Then comes a layer of artifacts typical of Amazon rainforest peoples, adopted by a “sambaqui”: a mound of pottery, shells and bones utilized by some Indigenous teams to construct their properties or bury their lifeless.
Beneath that, about 6.5 toes under the floor, lies one other layer, left by a gaggle that made rudimentary ceramics and lived round 8,000 to 9,000 years in the past, primarily based on the depth of the discover.

Scientists have lengthy debated precisely when and the way people arrived in and populated the Americas from Asia.
Lage’s discover suggests they settled this area of modern-day Brazil at the very least 1,400 years sooner than beforehand thought.
Archaeologists now plan up to now the artifacts extra exactly utilizing isotopic evaluation.
Already, the positioning “represents a landmark in our understanding of prehistoric Brazil,” IPHAN mentioned in an announcement.
“The invention … highlights the significance of archaeology in preserving the reminiscence and historical past of Brazil, providing useful insights into our ancestry and contributing considerably to the understanding of our origins and id as a nation,” IPHAN mentioned
Archaeologist Arkley Bandeira of the Federal College of Maranhao, which is constructing a lab and museum to deal with the artifacts with funding from MRV, mentioned in an announcement the positioning might present useful new insights into the tradition and historical past of historic peoples misplaced to the previous.
“These finds… play a vital function in narrating our lengthy historical past,” he mentioned.
The announcement of the invention got here simply as archeologists mentioned they uncovered a cluster of misplaced cities within the Amazon rainforest that was dwelling to at the very least 10,000 farmers about 2,000 years in the past in Ecuador.
