Hi all, 

Here’s an interesting plant find. I discovered it in a locality in Western PA known for producing good plant fossils. I’m thinking seed fern, maybe related to Alethopteris somehow but to be honest I’m not sure what the species is. Any help would be appreciated. 

Thanks in advance

 

 

Stratigraphy:

Connelsville Sandstone of the Casselman Formation of the Conemaugh Group.

Age-Late Pennsylvanian, ~305 MYA

Interesting.  I’m not sure but I am wondering if it is Saaropteris or maybe Noeggerathia?

I’m still not sure of the species, especially because primary vein does not travel the entire way up the leaflet. Here’s a more close-up image.

I think I got a positive ID for this one. I believe it is a specimen of Lescuropteris. Lescuropteris was a seed fern that was well adapted to being a climbing plant, or liana
