St. Clair Lycopod Leaves

[historianmichael]

I found these two pieces many years ago during a visit to St. Clair, PA (Llewellyn Formation; Late Pennsylvanian). I initially identified them as Cyperites but now I am starting to confuse myself because, as you can see in the third photo, these leaves are much wider than what I would normally attribute to a lycopod, which I have always understood to be long thin wispy leaves. The fourth photo is meant to provide a more close-up image of the leaves. Should I stick with the Cyperites identification or is there a more accurate identification? Any help is greatly appreciated

Calamites penultimate branches. External molds.

@Rockwood Thank you for your response. While doing some searching on other finds from St. Clair I came across another thread about Stigmaria rootlets. You can see in the second piece some of Stigmaria. They appear to be attached. What are your thoughts on that?

Your first picture on the right, is a give away. The rootlets are still attached to the stigmaria.

Possibly. Here is one for comparison.

Very interesting! Sometimes the greatest discoveries are ones that you stumped upon. Thank you both for confirmation on what I later suspected.

Lepidodendron or Sigillaria would be the most possible version.
