  1. Mean crown ages in Ma are given with the 95% HPD in brackets below. HPD, highest posterior density; Ma, million years.
  2. Both calibration approaches (A and B) are detailed, and results of analyses A and B repeated using the reduced data set that did not contain missing sequence data (‘no missing’ data).
