Circular chronogram corresponding to the best-fit calibration procedure implemented with BEAST (`Yule crown’). Contrasting colours are used to highlight major lineages in the tree. The placement of fossil (for crown nodes) and geological constraints is illustrated with yellow circles and green diamonds, respectively. Numbers on nodes correspond to those used in Table 1.
