Title: Re: paleonet Fossil id help requested

 I can use help on the identification of a fossil collected on a class field trip this past weekend.  The photo is at:   http://tigger.uic.edu/~plotnick/LoneStarQuarryFossil.jpg.  The scale, top to bottom of the image, is about 2 cm.   Locality is in Northern Illinois, from the LaSalle Cyclothem, upper Modesto Fm. - lower Bond Formation; Age: Upper Pennsylvanian, Missourian (Stephanian).  Typical Pennsylvanian mid-continent fauna, lots of Composita.

It's probably in the category of "oh yeah, I should have known that," but I don't embarrass easily. -

Some kind of conulariid.
