Lidar reveals 396 new geoglyphs in Amazon, expanding Aquiry civilization footprint

Lidar surveys across 4,400 km² in Amazonas and Acre identified 432 geoglyphs, 396 previously unrecorded, attributed to the Aquiry civilization (600 BC–850 AD). The discovery significantly expands known settlement density and suggests larger pre-Columbian populations than assumed. Implications for Amazonian archaeology and historical land-use models are substantial, though ground verification remains pending.
