1.55" Red Diademaproetus Trilobite - Hmar Laghdad, Morocco

This is a dark red, proetid (Diademaproetus antatlasius) trilobite from Hmar Laghdad, Morocco. It's laid out nice and prone and is simply stunning. This is only the second red Diademaproetus that I have had from the location.

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: 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.
