  1. ‘Node’ refers to placement on phylogeny in Additional file 3. Fossil ages follow the references, except that some ages are modified following [49], indicated with an asterisk. Calibration priors are lognormal; the 95% prior interval is given, followed by the lognormal mean and standard deviation in parentheses.
