Collection methods and comments
| Collection excludes: | some genera |
| Taxonomic list comments:"early Frick collections... labeled as '10 miles north of Harrison, west end'": Wang 1994 divided into four levels by three "banded layers": Wang 1994; Prothero 1996c explains that this cannot be equated to the UNSM A/B/C/D scheme because the lithostratigraphy is too different | |
