Nice Pliomera Fischeri Trilobite

This is a uncommonly seen but nicely reserved Russian trilobite, Pliomera fischeri. It was from the Lower Ordovician rocks near St. Peterburg, Russia. It's very 3D and pretty decent sized for the species.

Like nearly all trilobites from this area there is some restoration, mostly minor shell touchups on the top of the segments, somewhere between 5-10%
