RaideReX Posted September 28, 2019 Share Posted September 28, 2019 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.

Mark Kmiecik Posted September 28, 2019 Share Posted September 28, 2019 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. Mark. Fossil hunting is easy -- they don't run away when you shoot at them!
