Table 18 Summary of raw and ranked data used in the Spearman correlation test of stratigraphic level in the Hell Creek Formation (and equivalents) and maturity for Tyrannosaurus rex. The specimens are organized by stratigraphic level and the values used in the correlation test are given in boldfaced columns; tied HCF ranks were converted to midranks.
