Summary of results for 36 fossil penguins under Model 1. Post, the posterior probability that the phylogenetic age is within the palaeontological age range; BF, in support of the palaeontological age; phylo age, the phylogenetic estimate of the age, along with the upper and lower of the corresponding 95% HPD credible interval; error, the difference in millions of years between the phylogenetic point estimate of the fossil's age and the mean of its palaeontological age range; ESS, the estimated effective sample size for the phylogenetic age estimate.
