Prone 2.5" Asaphus Lepidurus Trilobite - Russia

This is a good-sized specimen of the Ordovician trilobite Asaphus lepidurus. It was collected from the Putilovo quarry in the St. Petersburg region of Russia. It's just over 2.5" long and is light out nice and prone.

Like nearly all of the trilobites from these layers there is some shell restoration as the shell tends to flake during collection. There is a patch of shell restoration on the left side of the tail and a few small patched along the top of the axis. Maybe 5% total.
