I think I see a crinoid, but what else?

I'm getting braver and will venture that there is at least one crinoid columnal mold preserved in this formation. I'm fairly certain, however, that the other two most prominent molds are not of a crinoid. How am I doing?

Having trouble with photos again, this is the what else but there are two. I just can't edit the pic to fit the post. 20171212_063415.thumb.jpg.dd2a455252e4c03333edcdc15bbc936b.jpg

Maybe part of a mollusc, like a pecten.

Your first item looks like molds of spiriferid brachiopods, and the second item looks like a cast of the coral Pleurodictyum sp. Something like this:

Thanks to Dave (shamalama) for the picture.

They're all in the same item, one "rock" different views. Are there likely more than one of the coral or more likely an interrupted mold of one? And do brachiopods have stems, because I'm sure I see a stem on what I thought was a crinoid in the first pic?

Different corals in one rock.  They were small round mounds.  :)

Unfortunately, I cannot see the details in your photos.  :( 

You may see stems in the piece, but the main imprint, from what I can make out, looks to me like an imprint of a spiriferid brachiopod.

Close. They have pedicles, the opening for which may look like a stem.

Okay, I see the brachiopods also now that you shared those images, very helpful. As well, what I thought were leaf or plant molds in others I have, I now think are brachiopods. I'm not going to dig them out to retake photos, but I do have this shot of the group. Can you tell if they are from this view? They are small, that is a small bread plate they are sitting on. 20170830_002815.thumb.jpg.b8f7a09a0e3a88942058d42c3aaf50a6.jpg

Aah, yes, I see the difference!
