1.6" Illaenus Oculosus Trilobite - Russia

This is one of the more uncommon species of Illaenus from the St. Petersburg Region of Russia, Illaenus oculosus. The tail is tucked but it would be about 1.6" long if outstretched.

Like nearly all trilobites from these quarries there is some restoration to repair shell that flakes off when the rock is broken during collection to expose the trilobites. The amount of restoration is much less on this specimen than many of the Illaenids, mostly some patches on it's head, maybe about 5%
