.85" Unusual Lichid Trilobite (Akantharges) - Tinejdad, Morocco
This is a beautiful, .85" long specimen of an unusual lichid (Akantharges mbareki) trilobite collected near Tinejdad, Morocco. These Akantharges are slightly different from the much more available Basseiarges trilobites mainly coming from Jorf. They have become few and far between on the market because the site is no longer collectable. This is a particularly well prepared 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 currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
