Huge, 3.75" Platyscutellum Massai With Crotalocephalina - Morocco

Huge, Platyscutellum Massai With Crotalocephalina - Morocco #191782

This is a HUGE example of a rare, scutellid (Platyscutellum massai) trilobite from Aatchana, Morocco. It measures 3.75" in length. It is 3.75" long and it appears part of the tail was crushed prior to fossilization. There is a 2.8" Crotalocephalina gibbus present on the other side of the stone. The base of the rock has been cut flat, so that it displays nicely without a stand. There is <1% restoration on both trilobites.

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.
