Hi, I have just purchased this Crinoid fossil cluster and I can't make out what the card that came with it says. I was hoping someone could hopefully help?

I have it down as saying,

Zenacrinus bairdi, Liberty formation, Leaves creek, Ohio, Ordovian period.

Thank you (hopefully!)

Xenocrinus baeri (Meek, 1872) 

 

The location might be Cleve Creek, but I'm not sure. 

Not terribly familiar with Ohio.

Caesar Creek looks more like it, any idea if what the card says is correct?

 

If the pluricolumnal visible in the first picture (left) is quadrangular in transverse view, it belongs to Xenocrinus baeri, so the crinoid crowns could be of the same species.

You can give me a cup of tea. :)

 

According to grydredgers.org/Jack Kallmeyer, X. baeri was found in the Liberty Fm. 

"

Xenocrinus is found in the Liberty and Whitewater Formations. The genus is also found in the U.K.

By far, the most distinguishing feature of Xenocrinus is its quadrangular stem. No other crinoid in the Cincinnatian has a square stem."

Thank you for the time again abyssunder, it is hard to tell the shape of them really. But it looks more square than not?

Definitely the stem in cross section is not round, oval, pentagonal or star-shaped.
