2.2" Coltraneia Trilobite Fossil - Huge Faceted Eyes

This is a 2.2" long (if outstretched)" 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. It was quarried at Ofaten Mountain, Morocco.

Excellent eye facet detail on this specimen. There is quite a bit of shell restoration on the right side of the thorax, probably about 15% of the shell in total.

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 with over 25k described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left a excellent fossil record.
