The Apiacás Lines
LiDAR reveals ancient Amazon settlement with structured layouts in Brazil’s Apiacás region.
Researchers from Dakila Research have identified potential archaeological remains known as Ratanabá in the Apiacás region of Mato Grosso, Brazil, using LiDAR technology. This site is thought to be part of an ancient settlement, possibly linked to early inhabitants of the Amazon, and features organized layouts that suggest human activity.
The discovery involved LiDAR scans from aircraft, which mapped 95 hectares of dense forest, revealing around 30 rectangular areas and 30 linear features resembling streets, some raised about 50 meters above the surrounding land. The project began in June 2022 with approval from Brazil’s Ministry of Defense and was supported by self-funding, along with surveys from the Brazilian Army and geography institutes. Rock samples from the site were dated by UNESP scientists, indicating an age that could reach back millions of years, though further analysis is needed.
Dakila Research president Urandir Fernandes de Oliveira described the find as a significant step in understanding the area’s past, while archaeologist Saulo Ivan Nery pointed to the straight lines as evidence of intentional construction. This suggests that early communities in the Amazon may have been more structured than previously thought. Ongoing work at 16 research bases in the Amazon aims to gather more data.
At the time of writing, the Ratanabá site is being studied to better understand its historical context. While the findings are promising, they require additional scientific review to confirm their significance. This discovery highlights the potential for new insights into the region’s ancient history as research continues. What stands out are the unusual findings that accompany this discovery, offering a glimpse into a potentially complex past.
Among the notable elements are metal artifacts and unusual stones found in the region, which differ from typical archaeological finds and suggest advanced craftsmanship or natural phenomena worth exploring. Additionally, rock samples dated by UNESP scientists hint at an age that could stretch back millions of years, adding an intriguing layer to the site’s timeline.
