1.9" Illaenus Oculosus Trilobite - Russia

This is one of the more uncommon species of Illaenus from the St. Petersburg Region of Russia, Illaenus oculosus. The head is tucked but it would be about 2.6" long if outstretched.

Like nearly all trilobites from these quarries there is some restoration to repair the shell that flakes off during collection of these trilobites.

The amount of restoration is much less on this specimen than many of the Illaenids; the right cheek appears to be restored.
