Here is an unusual trilobite from the Ordovician. This is a large specimen of Basilicus sp. from the Wolchow River area of Russia. This trilobite is perfectly prone and nicely articulated. Both free cheeks are present and tightly attached. This type of trilobite has extremely small eyes which are set close together. The eyes are beautifully displayed on this inflated specimen. The bug has great caramel color and contrasts nicely with the cream-colored matrix. It is well positioned on a large, natural plate of limestone. This is a very nice, large, outstretched example of Basilicus sp. from the Ordovician of Russia.
