Proportional probabilities (prob.) are from Bayesian reconstructions of six ordered maturation age categories (0 to 11, 12 to 23, 24 to 35, 36 to 47, 48 to 59, and ≥60 months) for males (M; Figure 5) and females (F; Figure 6). Model fitting comparisons were performed by fixing (‘fossilizing’) select nodes to the six alternative maturation age categories and comparing Log Bayes factors (LBf) to the lowest (best fitting) age category for the node based on the harmonic mean (hm).
