4.3" Flying Zlichovaspis Trilobite - Orange Eyes
This is a spectacular, 4.3" long specimen of Zlichovaspis rugosa. Beautiful preparation on this specimen preserving all of the tiny details. The limestone has been removed from around the fossil, leaving it "flying" on a pedestal of rock. Another unique feature of this trilobite is that its eyes are naturally orange! This is a rather uncommon feature that is seen on trilobites from certain localities from time-to-time.
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.
