Thomasville Stone and Lime Company quarry (Cambrian of the United States)

Where: York County, Pennsylvania (40.0° N, 77.0° W: paleocoordinates 37.5° S, 97.2° W)

• coordinate estimated from map

When: Vintage Dolomite Formation, Early/Lower Cambrian (541.0 - 513.0 Ma)

• The dark-gray limestone is distinctive from the typical mottled lithology of the Vintage and begins above a 5-foot band of cream-colored limestone, it is

•convenient to use the formational name Vintage for all carbonate rocks below the Kinzers Formation (fig. 2). The dark-gray limestone is probably involved in a regional change in facies, but a separate designation for these upper beds is not appropriate.

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified dolomite

• This overlying, atypical darkgray limestone unit of about 100-foot thickness is also assigned to the Vintage Dolomite. It is overlain in turn by a tectonically thinned section of Kinzers "phyllite."
• Fossil was found from about 10 to 90 feet stratigraphically below a darkgray

•limestone near the top of the section

Size classes: macrofossils, mesofossils
