1.9" Austerops Trilobite - Excellent Eye Facets
This is a detailed, Austerops trilobite from the Devonian of Morocco. It has nice shell detail including eye facets and has been prepared with air scribes and air abrasives so that it looks like it is ready to crawl off the rock. Only about 1% restoration along repaired cracks through the top 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 with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
