Ordovician Cryptolithus Trilobite Fragments

These pictures show fragments of the Ordovician Period Cryptolithus trilobite found in Carroll County, Kentucky. It was found in the Kope Formation.

The U shaped collar is visible at both ends but the middle is obscured. I want air abrasive clean this fossil to try and reveal the entire cephalon (if intact). Mystery object in the left top corner could be a starfish arm.

You will need to click to enlarge this picture. This is a rock plate that had one of the previous shown trilobite fragments. Herb from KYANA Geological Society (Louisville, Kentucky) was looking at this piece and pointed out that this could be a starfish arm.

I just emailed you with pix I took of a fossilized specimen that looks astonishingly like the ones you pictured.
