1.4" Brown Hollardops Trilobite - Foum Zguid, Morocco
This is a detailed, 1.4" long, chocolate brown Hollardops aithassainorum trilobite quarried near Foum Zguid, Morocco. Nice eye facet preservation in both eyes and no restoration. The genal spines have been prepared free standing. About 1-2% shell restoration along repaired cracks.
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 described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left a excellent fossil record.
