Note: Centrum counts are calculated for each taxon/morphotype per locality and formation, with the grand total of all specimens listed in the lower right-hand corner. ∑Tu/taxon, total count per taxon from the Tullock Member; ∑total/taxon, total counts per taxon across Tullock Member and Ravenscrag Formation; comb., combination of specimens from all localities across the Tullock Member or both geologic units; Fm., formation; Mbr., member; Pu1, Pu2, and Pu3, Puercan 1, 2, and 3 North American Land Mammal “age” substages, respectively. The alternating white and grey rows represent the higher-level taxonomic groupings and sample sizes used in calculating the relative abundance patterns shown in the Paleogene portion of Figure 22.
TABLE 2. Stratigraphic distribution of teleost operational taxonomic units recognized here through the late Maastrichtian and Paleocene. Taxa known to be present in each time interval are shown in bold type. Taxa that can be inferred to be present during a time interval based on their presence in younger and older localities are shown in lower case.
