"Most other localities in the vicinity of Tiffany are stratigraphically higher than Mason Pocket": Butler et al. 1981
the "Bayfield" or "Tiffany" fauna includes many localities other than Mason Pocket such as Carracas Station and Crowbar Creek (see); additional records based on Simpson and other sources include the following: Chriacus sp., named Chriacus metocometi by Van Valen 1978 ? Dissacus sp. Phenacodus grangeri type Phenacodus matthewi type (includes type of "P. gidleyi"; see Thewissen 1990) additional Phenacodus sp. Phenacodus magnus Thewissen 1990: collected after Simpson 1935 Periptychus "superstes" type Aletodon ("Platymastus") mellon of Van Valen 1978 from 50 m above quarry: Gingerich 1983c Oxyaena sp. Gingerich 1980a from "near Tiffany"; probably the same as O. sp. from "just north of Mason Pocket" of Van Valen 1966 "Ignatiolambda barnesi" type Simons 1960: "presumed basal part of Tiffany formation, east of the Florida River and west of the Ignacio, north of the Mesa Mountains, SW 1/4, Sec. 29, R 8 W, T 34 N, La Plata County"
