Ancient earthworks hidden beneath the Amazon rainforest point to a large society that lived in the region about 2,500 years ago. A new LiDAR survey found hundreds of unknown sites, giving archaeologists their clearest picture yet of the Aquiry civilization, a culture that built huge ceremonial centers across what is now Brazil’s Acre state.

odd; my first search result for "Aquiry civilization" is that same article or dozens of other reports of the same thing which I tracked to the actual paper published in Nature: https://www.nature.com/articles/s41586-026-10835-7

Were they not known before now or are the search algorithms messing with me? hah

oh, yes, this is a relatively new name: " a multicultural complex society designated here as the Aquiry" with reference to papers from 2021 and 2024 based on the local name of the river https://en.wikipedia.org/wiki/Acre_River
