What species is this fossil plant?

[Dino2033]

 I found this fossil plant in North Attleboro, Massachusetts and was wondering if anyone knew the species.

For me it seems to be either Sphenopteris, Eremopteris, Karinopteris, or Mariopteris. It definitely could be something else.

reminds me a little to Sphenopteris we found in northern germany, same age

I agree with Sphenopteris sp. for Genus.

Species may be harder to nail down.

There are 3 different species listed in the Rhode Island Formation.

Sphenopteris minutisecta is the more plentiful one found there, though.

Thank you for the inputs. Is there any defining characteristics that distinguish it to be Sphenopteris? Just would like to know for future finds.

You would have to find the description of the plants listed.

I see some Google searches in your future.

Unfortunately I see many, many searches in my future. I have to id hundreds of fossil plants in my collection for a project.

I would start with George's Basement.

Volume 1

Volume 2

Volume 3

 

Then, maybe search out PDF's of the Rhode Island Formation, and Narragansett Basin.

Then maybe look up the Fossil Flora of the Union Chapel Mine.

 

Good Luck!

WOW. That is a lot. Thank you so much with helping me get truly started.
