Red Cyphaspis Eximia Trilobite - Hmar Laghdad, Morocco

This is a red Cyphaspis eximia trilobite from Hmar Laghdad, Morocco. This rare species of Cyphaspis has four, small, horns on its glabella. I think this is only the second red one I've seen from Hmar Laghdad.

The trilobites were hard to find complete at this location, and according to my sources, the locality has been collected out recently, so the there probably won't be many more of these red trilobites coming onto the market.

The red coloration is due to high levels of iron in the silicified exoskeleton. A paper on this unique preservation can be found below.

Red Devonian trilobites with green eyes from Morocco and the silicification of the trilobite exoskeleton

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.
