2.7" Asaphus Intermedius Trilobite - Russia

 
 
 
 
This is a large example of the stalked eyed trilobite Asaphus intermedius from the St. Petersburg region of Russia. This is one of the more uncommon Asaphus species from the area, is 2.7" long, and nicely presented in the middle of a limestone slab. There is about 5% shell restoration, primarily along repaired cracks and on 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 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.
