Bargain, 1.7" Reedops Trilobite Fossil - Good Eye Facets
This is a bargain, Reedops trilobite fossil quarried from Morocco. The hard limestone has been mechanically removed so that it looks like it's ready to crawl of the rock. Preserved eye facets in both eyes with no restoration. There are some scratches on the shell from preparation, hence the bargain price.
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 currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
