Cypricardella tenuistriata pelecypod from the Panther Mountain formation

These next two specimens are Cypricardella tenuistriata pelecypod fossils. Both have the typical ovate shaped shell with a squared off posterior margin. The fact that the growth lines are very fine and not terribly distinct or raised eliminates the species C. bellistriata from contention.

Both fossils came from a roadside quarry on Cole Hill Rd. in Madison County, NY and come from the Panther Mountain formation (Devonian, Givetian stage) but the rock type is very similar to portions of the  Skaneateles formation (with which it is concurrent).

Specimen #1 - Right valve only


Specimen #2 - Left valve only
