Here is a rare trilobite. This is a Pseudobasilicus lawrowi from the Wolchow River area of St. Petersburg, Russia. This type of trilobite has a rounded cephalon with long, thin genal spines and very small eyes set closely together. The thoracic segments flare toward the rear of the trilobite, and the semicircular pygidium is almost smooth. This specimen is wonderfully prone and exhibits fine detail. The slightly protruding eyes are easily seen, and the thin genal spines are clearly defined. The bug has great, natural color and contrasts beautifully with the light-colored matrix. It is well presented on the sculpted plate of limestone that also contains a partial Asaphus trilobite and a brachiopod. This is a very displayable example of this highly uncommon Ordovician trilobite.
