Taxonomic list

• from a 10 sq. mi. area about 4 mi. N and NE of Lysite; Cottonwood Creek, Davis Draw, and Bridger Creek drainages (all are tributaries of Badwater Creek)
includes Basal, Middle, and Upper Cliff localities (= locs. 1-5, 6a, 6b, 6c, 7 - 9); CM 114 equals Guthrie's locality 6
interval is >= 40 m (Guthrie), <=80 to 100 m (Korth 1982)
this does NOT include the "Guthrie" series of localities from the Lost Cabin Mbr.
Korth 1982 suggests that Lambdotherium is not from this interval, but Guthrie did not include it in his list in any case
specimen of Bunophorus sinclairi is actually from CM loc. 34: Stucky and Krishtalka 1990
