| Reason for describing collection: | biostratigraphic analysis |
| Taxonomic list comments:all localities are in Washakie County except YPM 13, 15, 16, 167, and 184, which are in Big Horn County because YPM 192, 193, and 315 were included here by Schankler, there may be overlap with the Bobcat Draw Bonanza list | |
