Colorful, Ordovician Harpides Trilobite - Draa Valley, Morocco

This is a very colorful and currently undescribed species (and likely genus) of Harpides trilobite from the Fezouata Formation of Morocco. The coloration is natural and is the result of oxidization of iron pyrite. Some of the other specimens I've seen of this species have been painted to be a consistent color. Wonderful detail on the paraglabellar field.

It's been nicely prepared so that it stands out in high relief on the rock. There is a second unidentified trilobite as well as two negative impressions also present.
