Median age estimates and 95% HPDs for Hymenoptera obtained using a range of approaches to constructing a subsample of fossil occurrences and constraining their placement. These approaches consist of: a uniform subsample of occurrences with and without topological constraints, a uniform subsample of occurrences supplemented with the oldest unequivocal members of clades which were then constrained to their respective crown groups, a subsample consisting of only the oldest unequivocal members of clades with and without topological constraints applied to constrain them to their respective crown groups.
