a. Map of Amazonian sites with 1329 14C AMS dated charcoal fragments or burned archaeological material used in the summed probability analyses. Sites are color coded by geographic region: central (CA), eastern (EA), northwestern (WAN), southwestern (WAS), southern (SA) Amazonia, and Guiana Shield (GS). Symbols denote new 14C dates from this study (squares inside dashed boxes), and previously published 14C dates from soil charcoal surveys (circles) and archaeological surveys (triangles). Symbol size indicates the number of 14C dates at each site. Tree cover is shown as the fractional tree cover in proportions ranging from 0 to 1 for the year 2020 (Liu et al. 2024); b. Frequencies of 14C dates over the last 12,000 years for this study (left), previously published dated soil charcoal fragments from paleoecological surveys (center), or previously published dated material from archaeological sites (right).
