Pair of Crotalocephalina Trilobite Fossils - Atchana, Morocco

This is an impressive pair of colorful Crotalocephalina trilobite fossils, collected from the Lhandar Formation near Atchana, Morocco. The larger specimen is 2.8" long and the smaller one would be about 2.5" long if outstretched. Both are well prepared and the limestone has been expertly shaped to create an aesthetic display piece. Total restoration is only about 1% on this fantastic 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.
