A wonderful trilobite from the famous Penn Dixie fossil site in Hamburg New York. It is a partially enrolled ELDREDGEOPS trilobite that is slightly compressed so it is not completely round.

Here is a great example of the trilobites coming from this classic and well known site. The ELDREDGEOPS trilobites from this location exhibit outstanding detail right down to the eye facets and tubercles on the glabella. They normally are preserved with a rich black color on a dark gray or gray matrix. Many from this site are also preserved with outstanding inflated carapaces that make these trilobites very showy.

The trilobite itself is 3/4 inch.  The Matrix is an irregular gray matrix 6 inches by 4.
