.5" Red Proetid Trilobite - Hamar Laghdad, Morocco

This is a .5" long, red, proetid trilobite (Proetopeltis neglecta hamlagdadica) from Hamar Laghdad, Morocco.

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