Collection methods and comments
| Reason for describing collection: | biostratigraphic analysis |
| Taxonomic list comments:"60 feet below the Tullock Formation in the northeast quarter of sect. 17, T 22 N, R 43 E" Lofgren 1995 argues that direct superposition of this locality and Bug Creek Anthills is not demonstrable 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 | |
