Large Isotelus mafritzi From Ontario

This is a large, complete specimen of Isotelus mafritzi from the Ordovician aged Cobourg Formation. It's well preserved, inflated and nicely showcased on the squared off limestone block. These trilobites are not seen very often on the market anymore as almost all the quarries around Cobourg are now closed to collecting.
