Fossil Crinoid?

[Rock Hound]

Any idea what this specimen is?

(US Quarter is 24.26mm or 2.426cm)

It was gifted to me, without any location information.

I am not a collector of crinoids, unless I find them while hunting, by this looks like a calyx of a Eucalypocrinites, a Silurian crinoid. I believe these are found in the Waldron Shale of St. Paul, Indiana. It also has a pygidium of a trilobite on it.

Just letting you know that it isn't necessary to make a separate post for each picture, better to have them all together.

Thank you so much, for your input.  It is a very cool little fossil, in my opinion.  The nicest Crinoid I've got, by a long shot.

Thanks.  I'll try to remember, next time.

And please try next time to put your focus on the object and not on the surface underneath it.

I agree, it seems like a very nice Waldron Shale Eucalyptocrinites crassus but the photos are terrible.

Android phone.  Sorry.....  I took probably 30 pictures, then cropped and posted the ones which were in focus best.  The phone was auto focusing itself.

If you back off some the photos will be in focus but you'll have more stuff in the photo other than the fossil. Crop the extra stuff out and, voila, in-focus and mostly crinoid. Try it -- it works. All the photos in my members' gallery album are shot with an iPhone 7. (Mark's Mazon Creek Fossils -- take a look and see what's possible.)

I have found many Crinoid Imprints through the years, but never anything to compare to this specimen.  Many thanks, for the responses to this thread.  I was a young kid when my father purchased this specimen, and I remember him showing it to me the day he purchased it at a Gem & Mineral show.

Never encountered on my Blackview android phone which is not the best.

One more tip that may help with pictures, sometimes the background can throw off focus, try a plain background with no patterns.
