  1. Three calibration analyses were performed using: (i) two dated hydrogeological events; (ii) a dated fossil; and (iii) the ages of the two hydrogeological events and the fossil. The details of the calibration points are presented in the main text. The names of the nodes are given in the main text and in Fig. 1.
