Mazon Creek ID

[Lori A]

I'm updating a display of Mazon Creek fossils that has been in our biology department for a long time. I would appreciate any help with identification and naming.

(There were quite a few misspellings in the original display. I see one I missed - Asterotheca miltunii should be miltoni (or miltonii?))

Picture 1: Left is Crenulopteris acadica, right is correctly identified.

Picture 2: Left just looks like a piece of wood. Not sure why it's labeled as a fern. Closer pictures of the right are needed.

Picture 3: Left is likely Pecopteris of some sort, would need to see the venation to determine the specific name. Upper right is Annularia inflata. Bottom right is Asterophyllites equisetiformis.

Picture 4: Closer pictures of the left one would help, the right is Macroneuropteris scheuchzerii.

There was a spot on the old display labelled wood cast but things had been moved around and taken off.

Here are the close-ups - hope they help.

The Pecopteris pseudovestita is Diplazites unita. The Asterotheca candolleana, might best be called Alethopteris lesquereuxii, but the preservation leaves a lot to the imagination.  The Paleostachya weiss is not a cone and appears to be Lycopodites pendulus.

 

That's the best I can do,
