Summed probability distribution of 14C AMS dated charcoal fragments and burned archaeological material (N = 1329 dates over 303 sites) for the last 10,000 years

Caption

Summed probability distribution of 14C AMS dated charcoal fragments and burned archaeological material (N = 1329 dates over 303 sites) for the last 10,000 years (a) and a zoom-in of the last 2000 years (b). Panels (c) and (d) show the composite kernel density estimates based on 1000 iterations of randomly sampled ages for the last 10,000 years and 2000 years. The black dashed line in (c) and (d) is the mean probability of all 1000 iterations, and the green shaded areas are confidence intervals. Ship icon and vertical dashed line in (b) and (d) indicate the timing of the first expedition down the Amazon River in A.D. 1541.
