Summary:

Pg. 172-188. Tuscarora formation (white Medina sandstone) of Appalachian region of Maryland is chiefly sandstone, hard and massive, generally white or gray. Few fossils have been found, but it is undoubted equivalent of white Medina sandstone to north. Is found at widely separated points in Appalachian district. Is 1,500 feet thick in western part of district. Assigned to Silurian.
Named from Tuscarora Mountain, PA, [which extends along border line of Juniata and Perry Cos., central southern PA].

Fisher: New York State Museum Bulletin, no. 481, p. 21-23.


Summary:

A second eurypterid occurrence from the Tuscarora is reported at the Kishacoquillas Gap, central PA. It occurs in either a nonmarine or a brackish-estuarine environment. A definite age cannot be determined, but it is probably Llandoverian.
