I recently purchased a 40lb box of shale from U-Dig Fossils in Utah. Mid-Cambrian, Wheeler Shale Formation, House Range, Millard County, Utah. This morning after work, I split a smallish piece & one side had an odd dent, the other had an indistinct, slightly raised shape that sort of looked like a trilobite, so I started trying to find out if it was. This was the result. Using dental picks, a needle in a small pin vice, a # 428 Dremel wire brush (by hand) & another small, round nylon brush (Dremel) in another pic vice... and lots of patience. I think it's most of an Elrathia Kingii minus the cheeks (of course) measuring 1.5 cm in length. It isn't the cleanest & I have a bit more to do, but I wanted to "show it off" as it were. And see if I got the I.D right. Not the greatest quality pic, but I've also been up for almost 24 hours, so it may just be my imagination (pic quality or that I actually took a pic). :D

I'd agree, looks like an elrathia molt.

Nice prep, looks good. How big is it?

Yep, definitely Elrathia kingii. Nice prep, these often get butchered :dinothumb:
