What are these fossils?

[DitchLeeper]

Found these a couple years ago on another shelf rock creek in Callaway County, MO. Was told they were coral but never what species.Last picture was a fossil I found in a creek in SE MO. What do i have?

[Dave NWOH]

Not sure what they are but those are nice. That last one is super cool. Thanks for sharing.

looks like coral to me. Horn and some other...?

[CMD]

Yes, horn corals, and likely other coral types, and the last one is a crinoid column, or stem, showing how it was flexible. Crinoids are sometimes called sea lillies. That column in your last photo anchored the animal to the sea floor, with a crown atop the crinoid column.
