Where: Virginia (37.4° N, 80.9° W: paleocoordinates 29.7° S, 61.1° W)

• coordinate based on unpublished field data

• hand sample-level geographic resolution

• Holland and Patzkowsky, 1996 have the "Martinsburg" here as the "Reedsville"

•

•Based on Kreisa (1980, VA Tech Ph.D. thesis), this is "Martinsburg", probably "Trenton" equivalent
