1.8" Asaphus Platyurus Trilobite - Russia

This is an uncommon Asaphus platyurus trilobite from the Vilpovitsy quarry near St. Petersburg, Russia. It's 1.8" long and nicely prepared from the surrounding limestone. The hypostome (mouthplate) is visible underneath the trilobite

Like nearly all of the trilobites from these quarries they do have some shell restoration, as it tends to fracture during collection. It's pretty minimal though, a little bit year the front of the head, on the right genal spine and some crack fill on the tail. A beautiful specimen.

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