2.3" Elegant, Stalk-Eyed Cybele Trilobite - Large For Species

Elegant, Stalk-Eyed Cybele Trilobite - Large For Species #228083

This is a elegant, 2.3" long, stalk-eyed Cybele panderi trilobite from the Vilpovitsy Quarry in the St. Petersburg region of Russia. It's quite large for the species and magnificently prepared. There is about 7% shell restoration, primarily along a crack through the left hand side of the thorax.

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.
