A pioneering LiDAR survey in the Upper Amazon has revealed a hidden network of "Jaguar-Pawed" processional ramps leading to a massive circular plaza. The ramps are constructed from packed earth and faced with stones carved to resemble feline tracks. Comparative ethnographic research suggests these structures were the staging grounds for ancient lunar eclipse festivals, where participants mimicked the movement of jaguars to "frighten away" the shadow consuming the moon.
Excavations at the terminal points of the ramps recovered obsidian knives and broken feline-form pottery, characteristic of ritual termination ceremonies. This discovery challenges the long-held view of Amazonian societies as small-scale settlements, proving the existence of vast ceremonial landscapes designed specifically for recurring astronomical festivals that united geographically dispersed communities.
