ID needed Cretaceous NJ unidentified invertebrates

[OneLastSift]

Hello, I found this during my last trip to a NJ Cretaceous stream. I sometimes find Devonian coral fragments but have never found something like this. I believe the round parts to be remnants of crinoid stems but I’m unsure about the star shapes. Any help is appreciated, thanks!

Hi if a moderator could remove this I would appreciate it, I chose uncropped pictures and would like to make a new post. Thanks

 

edit: I edited the original post to include the correct pictures.

These are crinoid columnal imprints.

The asterisk imprints may be from crinoid calyx plates.

I guess that shape could also be indicative of a Cystoid plate. Echinoderm of some sort, at least.
