Summary:
Pg. 223. Centerfield limestone member of Ludlowville formation. Centerfield limestone is basal member of Ludlowville formation. Identified from Murder Creek, western New York, to east of Skaneateles Lake. Is especially characterized by variety and perfection of preservation of its fossils, most notably its corals. Characterized by SPIRIFER DIVARICATUS [brachiopod]. In Livonia salt shaft it is 19 feet thick; at Blossom, 4.5 feet; is probably 1.5 feet thick in cliff at Bayview, Lake Erie.
Type section: on Schaffer Creek, 1 mi north of Centerfield, [Canandaigua quadrangle, Ontario Co., central western NY].

Summary:
Peppermill Gulf bed is a newly recognized, fossil-rich horizon at the base of the Centerfield Member (and the correlative "Chenango facies") of the Ludlowville Formation. Overlies the Levanna Member of the Skaneateles Formation. Fossil bed consists of a bioturbated, silty mudstone with a diverse assemblage of brachiopods, bivalves, and some rugose corals. Outcrops extend from Big Hollow Creek on the west side of Cayuga Lake to Case Hill Ravine south of Syracuse. Age is Middle Devonian.

Summary:
At the type sections of the Centerfield and Ledyard Members in the Finger Lakes region, their contact is drawn between underlying relatively fossiliferous limestone and overlying black shale. Westward, near Lake Erie, the Centerfield/Ledyard contact has been defined biostratigraphically and marked a meter or more above the limestone. Author here proposes that a lithostratigraphic boundary be drawn at the uppermost limestone bed of the Centerfield throughout its geographic extent.
