Good day, I'm looking at this fossil fern plate from the Llewellyn Formation in St. Clair Pennsylvania. I suspect that these are Alethopteris ferns. I'd like some help to verify their species name.

Age:  Pennsylvanian
Formation:  Llewellyn
Location:  Near St. Clair, Pennsylvania

Could be serli or decurrens. I don't think the venation has enough detail visible, at least in the photo, to make the call down to species level.

Fossil hunting is easy -- they don't run away when you shoot at them!
