Is this fossil real or fake? What is it exactly?

Hello all! Another question from a fossil and geology newbie. I found a bag of interesting rocks in my home today. It contained what looked like store bought rocks but I have literally no idea where they came from or how I got them. Included were two fern looking fossils and I'm not sure if they're real or not. This is probably an extremely stupid question, but I just want to make sure. Thank you! :) (also my apologies for the terrible lighting in the photo, I can attach more if needed)

The ferns are real. 

They look like Mazon Creek nodules.

Nice! Of course, these 'ferns' probably aren't really ferns. At least, the Alethopteris is a pteridosperm ('seed-fern'): an extinct group of plants that had fern-like leaves but reproduced from seeds rather than spores. The Pecopteris is more problematic, and leaves given that name probably belonged to at least three different major groups of plants - including, in a few cases, actual ferns! :)

Can recommend:

The emphasis of this thesis is not on macroscopical aspects,however

 

extremely exhaustive in its treatment,but in parts outdated,and IN FRENCH(publ. 1932):

On the plus side :the  plates are HUGE(above:between 1/3 and 1/2 of the actual size:P) and razorsharp(to the right:Pecopteridium(Palaeoweichselia)defrancei)

 

Orue(2013) has published a useful taxonomical overview of Pecopteris(in Spanish),which helps in deciphering which parts of the comprehensive thesis to the right(below)

might be outdated.

As has been repeatedly pointed out,in Paleozoic plants macroscopical anatomy isn't TOO reliable a systematic criterion(by itself)
