The data are also grouped according to two practices, cranial modification and the application of red pigment to crania, separated by valley area (lower and middle). Lines and colored circles indicate the median birth and death date, respectively; probability distributions are not shown for simplicity’s sake. The distributions are non-Gaussian; the average length of the 95% uncertainty range is 132 years, comparable to an error of ±33 years. Some individuals appear in multiple plots; for example, all individuals from the family ossuary with aDNA data have north coast ancestry. All dated individuals from the family ossuary have both cranial modifications and red pigment.
