Divergence timings of the genus Duttaphrynus. Bayesian maximum clade credibility chronogram of the genus Duttaphrynus inferred in BEAST (Analysis 2) with median divergence times and associated 95 % highest posterior distributions of dates in brackets. Timings of relevant geologic events are illustrated: A – Red Sea formation (27–23 Ma); B - Gomphotherium bridge (18–16 Ma); C – permanent Eurasian landbridge (15 Ma); D – southern Afro-Arabian landbridge (10–5.3 Ma). Ranges of Arabian species and, if relevant, corresponding sister taxon are illustrated. Filled circles on nodes represent Bayesian posterior probabilities > 0.95, open circles represent support values < 0.95.
