This is a stalk-eyed, 2.8" long Asaphus intermedius trilobite from the St. Petersburg region of Russia. This is one of the more uncommon of the asaphus species. It has a slight arch to it but is quite 3D.

Shell restoration appears to be less than 5% on this example.

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.
