Taxonomic list
• 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"
