Two Colorful, Harpides Trilobites - Draa Valley, Morocco

This is a pair of colorful and I believe currently undescribed species of Harpides trilobites from the Lower Fezouata Formation of Morocco. One is 2.2" long, the other is 1.7" long and they are both exceptional examples of the species. Very nice preparation on this unique collector piece.

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.
