Triassic Cumnock formation North Carolina Cyzicus and unknown plant?

[fossil_lover_2277]

So I just made a trip to a publicly accessible creek that cuts through the Triassic Cumnock formation of North Carolina. Made a couple of nice finds. An unknown plant fossil, it’s worn down a bit, but anyone think they can ID? Also found a TON of what I believe are Cyzicus fossils, the largest are just shy of 1cm. Can anyone confirm these are Cyzicus? Thanks for the help!!!

Is the "plant" as three-dimensional as it looks in the picture? I think it is rather trace fossils, perhaps some kind of burrows.

Yes the structure is “3D” as you say. They are a raised structure on the rock, they’re not just flat traces

 

i thought about burrows, but the structures have such a uniform shape, didn’t think that was it, but I could be wrong. Like they’re really straight and overlap one another

These have been called Cyzicus but are probably a different genus. The NC Fossil Club publication labels these as Euestheria.

Thanks for the help, that makes a lot of sense! I was also wondering, does the fossil I called a “plant” look like burrows to you?

The burrows could be Thalassionides, but I'm not familiar with your area.

Those are in fact an ichnofossil. As for the name, I’m curious too as I have similar specimens from Utah from a few years back I have yet to identify.

I found a publication that referred to them as “Scoyenia”...and the fossil may actually be from the Pekin formation, not the Cumnock, the creek it’s from cuts through both formations

the “Cyzicus” compression fossils are definitely Cumnock formation shale

Yup I found a matching pic from a publication online, definitely looks like Scoyenia

Yeah, I’d agree to the genus for sure. I never trust ichnos with a species name, personally!

good find thanks for the info!

It could be a good match!
