This might be different...... I think it could be Orthogoniopteris. I had Marietta college send me photos of their specimen of this back in the summer. I'll try a comparison.

Very Cool, Sherry!

I love the detail there is to your plant fossils.

Nice preservation.

Here's the illustration of Orthogoniopteris clara and Orthogoniopteris gilberti. I'd previously thought these could be a match for the thing we call "Danaeites", but the size is too large. But I think this new one is a match.

EDIT: In the illustration, 1) Orthogoniopteris clara, 2) Orthogoniopteris gilbert, and 3) alethopteris maxima. (From base of coal measures in Rushville, Ohio)

Here's the photos of the type specimens that I requested from Marietta College. These are the fossils used for the illustration. Looks like it could be a match for the one called O clara.

It also looks to me like the cf "Danaeites" and this new one Orthogoniopteris should probably be in the same genus since they are nearly identical except for the overall size. One has pinnules that are 1 cm wide and more undulated. The other has pinnules that are 2 cm and not undulated. They might even be a variation of form of the same species.

Well Paul, had no idea this was a new one. Very thankful my site keeps on giving..... Looks like a match to me of the specimen from Marietta College. It was not found with the Danaeites I found today though, Thank you Fossildude19!
