Identification as Pecopteris is very likely. This comes from a newly found shale landslide. The piece had fell out of the hill and was lying on the ground. The rock is very fragile. The colors shown are more rare in this area, more commonly being a grey shale with black leaves.
This genus of leaves is very common overall and very common in my area. It is most commonly found below the Limestone layer. I do not believe I have found one between my local Limestone and the Ames Limestone above.
I have also found a much larger leaf from the same time period called Macroneuropteris.
