2.8" Illaenus Sinuatus trilobite - Russia

This is a big specimen of Illaenus sinuatus from the St.Petersburg Region of Russia. It's head is tucked but it would be about 3 inches in length if outstretched. It displays nicely on the sculpted block of limestone. Shell restoration is pretty minimal, a small patch on the tail and a little bit in the cracks on the head, maybe 1-2%
