2.3" Bug-Eyed Coltraneia Trilobite - Unique Coloration

Bug-Eyed Coltraneia Trilobite - Unique Coloration #69615

This is a 2.3" long, bug-eyed, Coltraneia trilobite with amazing "tower eyes" full of hundreds of eye facets. The species has often been referred to as a Treveropyge in the past. The shell coloration on this one is different than most being brown instead of black. I suspect it's not from the typical Ofaten Mountain location, but I'm not sure. Good eye facets in the left eye, though the right eye is a little distorted.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
