Crinoid? Cephalopod? Other marine life?

[Skellyborden]

Hello all, and thanks for being here! I am looking for an ID on these fossils for my own gratification! My focus is in archaeology, so I come across fossils often during surface collection adventures! 

A little about the location: 

These were found in Nancy, Kentucky, USA on a partially man made flood-control lake called Lake Cumberland (Cumberland river basin/Cumberland plateau).

The banks are rich with small to medium chert concretions, fossiliferous sedimentary stones, and small to medium iron inclusions. 

Preservation of these specimens are, generally, fair to good. 

I found this piece along with horn corals, only a couple of brachiopods, and a wealth of crinoid stem pieces in less than 20 minutes!

 

I thank you all in advance for any information you can give me!

Crinoid stem. Just barely.

First two are crinoid stem pieces.

Not sure on your third item. Maybe a bryozoan or sponge?

I agree that specimen 1 and 2 are very possibly crinoids. Specimen 1 may also be a straight shelled cephalopod, also referred to as an orthocone. To my eye, specimen 2 is interesting since if it is a crinoid, it seems to have undergone significant post burial compression and deformation. What was once a round crinoid stem has been compressed into an ovoid shape and the individual segments that had stacked on top of each other neatly are now deformed so that they sit on top of each other at an angle. Someone can correct me if they know of any crinoids that are oval rather than round. My best guess from the texture of Specimen 3 is sponge.
