For each fossil, the calibration node is highlighted in bold, and alternative, reasonable fossil placements are indicated. The prior probability distribution for the constrained node, and the joint prior and posterior probability distributions of the constrained node and alternative fossil placements are indicated (millions of years). Numbering corresponds to node numbers in Fig. 3.
