First of all, is this a hypostome? If so, is it a damaged one from  Isotelus? Found in the Kope Formation, Ordovician along AA Highway in Kentucky. Thanks for looking at it and giving an opinion.

@Mark Kmiecik, good eye! I purposely trimmed this piece to preserve that pygidium.

I bet if you looked close with a microscope you would find a few scolecodont teeth.  Packy
