Maximum clade credibility (MCC) species tree estimated in *BEAST. Grey bars show 95 % HPD for node ages. 95 % HPD for root node extends to 20 MY (shown as a dashed bar). Red dots show node posterior probability (pp) ≥0·99; black dots show 0·8 ≤ pp < 0·9. Unlabelled nodes had pp < 0·8. Red dashed lines show 100 000 years and 1 million years before present.
