3.15" Zlichovaspis Trilobite - Laatchana, Morocco
This is is a very detailed, 3.15" long specimen of Zlichovaspis rugosa from Laatchana, Morocco. Visible eye facets in both eyes and excellent preparation. The very tip of the right genal spine is missing but it has not been restored.
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.
