Summary of models and parameters available for morphological characters that were tested and implemented herein. ACRV, among character rate variation; Asym, asymmetric state frequencies; BI, Bayesian inference; FBD, fossilized birth-death model; GA or ga, Gamma distribution; IGR (independent gamma rates uncorrelated clock model); LN or ln, lognormal distribution MML (SS), marginal model likelihoods (using the stepping-stone procedure); NoSA, no sampling of ancestors; PMF, probability mass function; SA, sampling of ancestors; SFBD, skyline fossilized birth-death model; Sym, symmetric state frequencies; TK02 (Thorne and Kishino continuous autocorrelated clock model). See the “Methods” section for additional details and explanation for different models
