Rare, 1.6" Leningradites Graciosus Trilobite - Russia

This is a fairly rare trilobite species from the Lower Ordovician deposits near St. Petersburg, Russia. It's a 1.6" long Leningradites graciosus that was collected from the Vilpovitsy quarry. It's nicely preserved with prominent eyes and the genal spines have been prepared free of the surrounding limestone.

There is some restoration to the very tips of the genal spines, and some shell restoration on the last two segments of the body. Probably about 5% in total.

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 with over 25k described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left a excellent fossil record.
