I have 2 Pennsylvanian fossils from Mazon Creek. They have previously been identified as crenulopteris and lobatopteris lamuriana. Presumably the crenulopteris specimen is a seed fern; however, I am unsure about the lobatopteris lamuriana specimen. Presumably the lobatopteris was once labeled as a pecopteris so is it still considered to be a seed fern? Any information or suggestions would be greatly appreciated. The first image is of the lobatopteris specimen, The next image is of the crenulopteris specimen.

I recently had a split of material collected from Pennsylvanian age spoil piles in Indiana that appears to be a fragmented fertile Fern and it sparked my interest on older finds that I have yet to identify.I found a post from Roby that reminded me of a fossil that I found 7 years ago.Is this an example of Crenulopteris Mazoniana?

Below is the fertile fern found in pit 2 fall 2019. It was identified by Fiddlehead early this December as being Crenulopteris mazoniana. The significance being the rarity of fertile ferns in the Mazonia fossil flora. Hope to gain more information on this specimen in the new Flora book once publish.
