This is my third and final request for an ID today!!! I lean towards this being a trilobite. If there is doubt, I will use a hammer to help expose this. If it is likely a trilobite, I will work on it in a little less physical way. It was collected 2 weeks ago in SW Wisconsin, Platteville Formation, Ordovician.

I don't see trilobite, but you know me -- I'm often very wrong. However, I am fascinated by the ripple pattern that surrounds it. Ichnofossil perhaps? And that super-tiny crinoid columnal on the lower right is really cool.

Fossil hunting is easy -- they don't run away when you shoot at them!

It might explain the somewhat strange segmentation. I don't think a hammer would expose anything better than what you already have.

Fire up the compressor and reveal more with the scribe, I'd say. Better safe than sorry!
