A group of Brazilian archaeologists made a surprising discovery at the Lago do Cochila site, located in the Amazon rainforest. In early 2025, they uncovered seven clay spheres that experts believe were used as funerary urns by an ancient indigenous civilization. These objects came to light after the collapse of a fifteen-meter tree, revealing their location after being buried for centuries or even millennia.
Although their exact age has yet to be determined, they are estimated to be pre-Columbian. The urns measure up to 89 centimeters in diameter, and two of them contained human remains, while the others were filled with seeds and animal remains, suggesting a ceremonial use.
Archaeologist Geórgea Holanda from the Mamirauá Institute for Sustainable Development noted the absence of ceramic lids on these urns, indicating that they were sealed with organic materials that are no longer present. This finding is part of a complex funerary process that includes exposing the body to the river for decomposition and subsequent cremation of the bones.
The archaeologists faced significant challenges in accessing the site, including seasonal flooding. Collaboration with the local community of São Lázaro do Arumandubinha was crucial for the success of the excavation, allowing researchers to select the most appropriate times to work in the area.
