Gorgeous Pair Of Crotalocephalina Trilobites - Atchana, Morocco

I had this piece in my personal collection for the past few years.

It is a stunning pair of Crotalocephalina trilobites from the Lhandar Formation of Morocco. The multi-toned shell coloration on this is gorgous, and the preparation is fantastic. One specimen would be about 3.2" if outstretched and the other would be around 2.5". A really aesthetic display 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.
