Rare Thaleops Ovata Trilobite - Wisconsin

This is a rare trilobite from Wisconsin, Thaleops ovata. I've had this particular specimen in my own collection for over a decade and decided to part with it to pay for some more collecting trips this season. It's Middle Ordovician in age and comes from the Mifflin Member of the Plateville Formation. This is certainly a trilobite you won't see come up for sale very often.

Note: The left genal spine on this trilobite has been restored.
