3.55" Crotalocephalina Trilobite - Atchana, Morocco
This is a beautiful, 3.55" long, specimen of Crotalocephalina gibbus from Atchana, Morocco. Nice preparation and shell detail. It's good sized for the species and laid out nice and prone. The rock has been removed from underneath the tail spines and head creating a very aesthetic display. There is some shell restoration to the very front of the head.
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.
