This is a very distinct specimen of Asaphiscus wheeleri from the Cambrian of Utah. This type of trilobite has a huge, semicircular cephalon and a large, somewhat rounded pygidium. This large bug is nicely preserved in a prone, outstretched position. The dark color of the fossil contrasts wonderfully with the lighter-colored matrix. The trilobite is well showcased on the large plate of shale. This is a very nice example of a complete Asaphiscus from the House Range.
