Collection methods and comments
| Reason for describing collection: | taxonomic analysis |
| Collectors: | Lamothe, Chew |
| Taxonomic list comments:may equal either Little Dry Creek or Big Dry Creek in Sweetwater Co., or Little Dry Creek in Uinta Co.; based on reference of Gingerich 1979a I believe it is in Uinta Co. "Pauromys perditus" type of Troxell 1923a is probably but not certainly from the lower Bridger "Limnocyon verus" Thorpe 1923a: level not stated "Viverravus gracilis" Thorpe 1923a: level not stated "Hyrachyus eximius" Wood 1934: "Dry Creek (hence C or D)"; "H. princeps" from same; if these are in Sweetwater Co. they may be from the lower Bridger instead Siren dunni Goin and Auffenberg 1957: Lamothe and Chew specimen in the YPM from "Dry Creek, Bridger Basin, Sweetwater County" | |
