Tricopelta brevicepsWhitewater FormationUnion County, IN
OrdovicianHere is a very rare and superbly preserved trilobite, Tricopelta breviceps. This trilobite is rarely found and is one of the most sought after trilobites from the Midwest. This particular trilobite was found in the same localized collecting area as my Ceraurinus icarus/Cupulocrinus polydactylus association piece. This trilobite measures 1/2" wide.
