1.4" Spiny Leonaspis Trilobite - Beautiful Shell Detail
This is a well prepared, 1.4 Leonaspis from Atchana, Morocco. It has excellent, chocolate brown shell preservation and is well prepared. Both of the genal spines have been prepared free-standing and it has about 1-2% shell restoration in total.
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.
