Trying to Add IDs to our YT video and this one is not on the "ID Key"  at the paleo site. I will include the ID Key for identification purposes, thanks in advance!

Looks to be one of the species of Composita, just with very pronounced growth lines.  A picture of the other side would help to confirm that.

That looks like Composita subtilita (Hall, 1852). Super common which is why they included it in the top left of the signage. The view in the guide is of the brachial valve and your view appears to be the pedicle valve.

Thank you, I wish I had a photo of the other side, but this is just a still from our video.
