Bargain, 2.6" Hollardops Trilobite - Visible Eye Facets
This is a bargain, 2.6" long Hollardops merocristata trilobite fossil from Ofaten, Morocco. The preparation is a bit rough leaving some scratches and dings on the shell, hence the bargain price. There is some minor shell damage and restoration to this specimen.
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.
