Pennsylvanian Seed from the Manning Canyon Shale, Utah ID

[Nimravis]

Here is another item that I am looking for an ID on- It is a Pennsylvanian seed from the Manning Canyon Shale, Utah. I am thinking "Trigonocarpus" or "Cordaicarpus"- any suggestions or ID?

Looks like Cordaicarpus. What kind of plant fossils are present in the formation?

 

For comparison, an example from the Pennsylvanian of Kansas City:

I agree with Missourian, your find looks like Cardiocarpus. Trigonocarpus is typically longer than it is wide and oval shaped.

I might have found some Cardiocarpus from the Llewellyn formation of St. Clair. Just dug out some examples from a box.

Shamalama......your finds look like fish scales to me.
