paleonet Ordovician mystery fossil

[JAMES STJOHN <stjohn.2@xxxxxxx>]

To all paleonetters,

Hi - I'm hoping someone can identify a mystery fossil found by one of my undergraduate students on a geology field trip this past spring.

Below is the internet address of 2 photos of the fossil.  The file posted here will take several moments to open up.

The pics aren't fantastic, but I think they're sufficient to show the morphology.

I initially (& naively) thought it might be a broken segment of a stelleroid (starfish or brittle star), but a starfish/brittle star worker has told me definitely NOT!

The fossil is 5 mm x 3 mm in size.  It was found as float, derived from either the upper Waynesville Formation or the lower Liberty Formation (Richmondian Stage, upper Cincinnatian Series, upper Upper Ordovician).  It was found at Caesar Creek Lake's emergency spillway, northeastern Warren County, southwestern Ohio, USA.

Any thoughts or suggestions?  If so, please contact me off-line at:
stjohn.2@osu.edu

If a reasonable ID comes along, I'll post that info. to the entire list.

Thanks for your time,

James St. John
