I found this while hunting for agates in a quarry in the Driftless region in Wisconsin along the Iowa border. I was thrilled to discover a tiny fossilized leaf but on closer inspection (and other input), I don't believe this to be a leaf.
Please note that there appear to be pores and there is an appearance of something faintly looking like a tail or stem at the bottom of the close-up picture.
I attached the final picture not knowing if other fossil object remnants or not, and if these could give further clues.
Any assistance on identification would be appreciated. Thanks!

I cannot help on an identification but YES this is part of a Trilobite pygidium. Nice find! The marks on the back do not look like anything I know.

Cheers,

Pim

Thanks a lot, Pim! I honestly don't know what characteristics make this so, as I am a newbie, but I really appreciate your assistance! I plan to learn a bit more about this. :)

Couldn't this be an imprint of some sort of bivalve too?
Do you know something about the stratigraphic origin of the piece?


Best wishes,
Oliver

Hi. It was discovered in a dirty rock pile in a quarry while looking for agates. Sorry. so the region is all I know.

Without a doubt, this is an imprint of a trilobite tail section. The 'pores' are tubercle imprints. Without stratigraphic context, it is very difficult to ID this specimen.
