Where: Fayette County, Pennsylvania (41.0° N, 79.6° W: paleocoordinates 12.6° S, 22.3° W)
• coordinate based on political unit
• outcrop-level geographic resolution
When: Wymps Gap Member (Mauch Chunk Formation), Brigantian to Brigantian (336.0 - 327.0 Ma)
• Upper Mississippian. "The Wymps Gap Limestone Member is a thin, marine tongue extending from the Union Limestone (Chesterian) in West Virginia."
•JA: originally entered as "Chesterian," but based on conodont stratigraphy this collection is specifically "pre-Glen Dean" in age (Horowitz and Rexroad 1972) and therefore Brigantian or Pendleian
• member-level stratigraphic resolution
Environment/lithology: offshore shelf; lithified carbonate and shale
