Taxonomic list comments:"80 feet below the Tullock Formation in the west half of sect. 9, T 22 N, R 43 E"; see map of Fastovsky and Dott 1986 see also Archibald et al. 1987, Swisher et al. 1993; based on Lofgren et al. 1990 and Lofgren 1995, fauna is mixed; I have sorted out Paleocene and reworked Cretaceous lists based on Lofgren's scheme well below the Z-Coal, but correlation is indirect: Fastovsky and Dott 1986 |
