Indian Creek bed of Windom Member of Moscow Formation is informally named in this report. Unit is a highly distinctive crinoidal pack- and grainstone bed, up to 20 cm thick occurring along Indian, South Indian, and Simpson Creeks in the town of Willard, western NY. The bed is compact, highly fossiliferous, and pyritic and contains extremely abundant, corroded crinoid ossicles, rugose corals, and brachiopods. Locally resembles the Tichenor Limestone. Bed is obviously lenticular as no similar thick bed has been located beyond the east Seneca Lake region. Bed unconformably overlies strata in the lower Windom, the Smoke Creek and Bay View beds having been locally eroded. Underlies 2.1 to 3.9 m of sparsely fossiliferous, medium gray shale with a distinctive satiny sheen that may be a local facies of the Bear Swamp beds or an expanded facies of the Fisher Gully beds. Resolution will require more detailed study. Age is Middle Devonian (Givetian).
