Petalodus12 Posted May 16, 2020 Share Posted May 16, 2020 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.

Strepsodus Posted May 16, 2020 Share Posted May 16, 2020 Interesting. I’m not sure but I am wondering if it is Saaropteris or maybe Noeggerathia? 1 Link to comment Share on other sites More sharing options...

Petalodus12 Posted May 17, 2020 Author Share Posted May 17, 2020 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. 1 Link to comment Share on other sites More sharing options...

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 2 Link to comment Share on other sites More sharing options...
