This is a huge example of a classic trilobite. It is an extremely large Eldredgeops milleri from the Devonian of Ohio. This type differs from Phacops crassituberculata in the number of eye lenses and in the fact that it has round, rather than angular, eye facets. The trilobite is beautifully prone and very nicely articulated. The fossil is preserved in a very 3-dimensional manner and exhibits fine detail - the coarse pustules on the glabella are very easily seen, and a pyritized epifaunal brachiopod is preserved on the exoskeleton. The eyes of the trilobite are nicely showcased - almost all of the individual lenses of both eyes are beautifully displayed. The trilobite has excellent chocolate-brown color that contrasts wonderfully with the light grey matrix. The bug is well positioned on the large block of limestone. And did I forget to mention this bug is OVER THREE INCHES LONG - the almost unattainable size for outstretched Ohio Eldredgeops! This is not only an excellent specimen of Eldredgeops milleri, it is one of the largest ever found - enough said.
