2.55" Asaphus Holmi Trilobite - Scare Asaphid

 
 
 
This is one of the harder to find Asaphid trilobites from the St. Peterburg region of Russia, Asaphus holmi . It's got some of the longer stalk eyes of the Asaphus, though not as long as Asaphus kowalewskii.

This particular specimen has no restoration which is quite unusual for Russian asaphid trilobites who's shell likes to flake off during collection.

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.
