Rare, 3.05" Ptychopyge Volkhovense Trilobite - Russia

Rare, Ptychopyge Volkhovense Trilobite - Russia #178242

This is a rarely seen Ptychopyge volkhovense trilobite from the Putilovo Quarry in the St. Petersburg Region of Russia. It's missing the right hand side of a couple of segments and has a pretty significant amount of shell restoration hence the bargain price for such a rare trilobite.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
