Maximum credibility tree for African Ricinulei and outgroup taxa, obtained by Bayesian inference in Beast [19]. 95% Confidence intervals for ages are represented by bars at nodes. Clade posterior probabilities above 50% are indicated above nodes and maximum-likelihood bootstrap frequencies below nodes. Posterior distributions for nodes of interest are also depicted below the tree. Palaeogeographic maps from Ron Blakey, NAU Geology at http://jan.ucc.nau.edu/~rcb7/.
