Summary of maximum-likelihood model-fitting analyses. Sample size–corrected
Akaike’s information criterion (AICc), model parameter values, and AICc weights
are documented for each analytical permutation. For the AICc values, we report the
mean and standard error based on multiple dating and topology replicates, as
described in the text. The results from this table are visualized in Figure 9. The best-fitting evolutionary models
are highlighted in bold for each analysis: lowest AICc value, highest AICc weight.
MSL, maximum skull length; BM, Brownian motion; and EB, early burst.
