Unknown Fossils From Mississippian Formation

I did some fossil hunting at the Fort Gibson dam area in Oklahoma this weekend and found some fossils I could identify (blastoids, crinoids, Archimedes bryozoans), as well as some things I can't identify.

I would appreciate any help you all can provide.

A friend suggested this may be part of an Edrioasteroid, and that seems to fit the bill, but thought I would get some more opinions.

Obviously, there are several fossils here. I'm thinking the prominent item with little pinholes could be a Rhombopora.

I suspect the "edrioasteroid" is a goniatite-type cephalopod. Apart from the "spiral" structure there is nothing resembling the ambulacral structure or plates of an edrioasteroid.

Trying again with the actual images in the post.

#s 4 & 5 look like bryozoans to me (unless they are a lot bigger that I take them to be).

Good photography, bu the way!

Thanks Auspex. I had them both tentatively labeled as bryozoans. I think #4 could be Rhombopora. In my first post in this thread I commented on which of the photos are macro and I kept the same order when I reposted the photos. So yes, many of these items are very small.

Thanks for your help, TqB.

I have looked at some Chaetetes photos, per your suggestion. I'm not sure if that's what I have or not. The fine scale details look different when I compare to the macro photos of my fossil.
