3" Asaphus Holmi Trilobite - Russia

This is a good-sized, 3" example of one of the scarcer Russian asaphids, Asaphus holmi. It comes from the Vilpovitsy Quarry in the St. Petersburg region of Russia.

Like most of the trilobites from this area there is some shell restoration as the shell tends to flake off during collection. Most of the restoration is on the end of the tail.

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.
