veenasaur Posted August 28 Share Posted August 28 I gathered these fern fossils from Cory’s lane in Rhode Island recently. Need some help with their identification. My guess is they look like Pecopteris but any more specific identification would definitely help. 1 Link to post Share on other sites

Bguild Posted August 29 Share Posted August 29 Cool finds! Cory’s Lane is a great spot. I think you’re right, these look Pecopteris sp. indent. It’s hard to see, but I think I can make out a few mid veins extending fully to the end of the pinnules. The majority of the Pecopteris that come out of Cory’s Lane are Pecopteris arborescens so if I were a betting man I’d guess that ID, but can’t really be certain without more detail preserved. I think Alethopteris would have a more confluent base than what I’m seeing here. 1 Link to post Share on other sites
