.95" Red/Purple Cyphaspis Eximia Trilobite - Zireg, Morocco

Red/Purple Cyphaspis Eximia Trilobite - Zireg, Morocco #287139

This is a .95" long, specimen of a fairly rare Cyphaspis eximia from Zireg, Morocco. This purple coloration is unique to the location and due iron based minerals being present during the shell replacement. Cyphaspis eximia can be identified by the presence of four small spines on its glabella.

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.
