Pennsylvanian Plant ID Help

Recommended Posts

On Saturday I took a trip to collect some Late Pennsylvanian plant material from the Llewellyn Formation of Pennsylvania. I am still working through my finds and identifying everything, but as an initial matter I had a question about two pieces. I have a guess on what they can be and was hoping someone might be able to confirm my suspicions. Any help is greatly appreciated. Thank you!


First, I believe that this fossil preserves the cell structure of a Calamites stem

Second, are these the terminal shoots of Asterophyllites? Unfortunately some of it broke in transport back to my house but I took a more complete photo of it in the field.

I found a similar example on another piece
