Bargain, 10.8" Large, Asaphid (Basilicus) Trilobite - Morocco
This is a 10.8" long Basilicus trilobite from the Fezouata Formation of Morocco. These large Asaphids are quite rare to find complete now days. They are found in limestone lenses within the massive shale unit of the formation. These limestone lenses are only exposed through erosion, a pretty slow process in the desert. Over the decades the sites have been scoured by diggers who have broken down all of the exposed lenses. I spent a week at the site with several diggers last year and we only found a single, large, complete Basilicus.
This specimen is bargain priced because both of the cheeks were missing (it was a molt) and they have been restored. It comes with a display stand.

About Trilobites
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: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
