  1. The maximum clade credibility chronogram was calibrated such that the divergence of Hoita and Pediomelum was scaled to 5.8 mya. r = net diversification rate (speciation events per million years); a = extinction fraction; st = time of rate shift (mya); k = carrying capacity parameter; x = rate change parameter; Ln(L) = Log-likelihood; AIC = Akaike information criterion; ΔAIC = change in AIC relative to pureBirth.
