5.8" Rare, Lower Cambrian Gigantopygus Trilobite - Issafen, Morocco

This is a very nice, 5.8" long example of Gigantopygus papillatus (Hupe’ 1953) from the Issafen Formation of Morocco. This large trilobite is one of the rarer species found in this fauna and this is an exceptionally nice example. It is nicely presented on a large section shale.

Comes with an acrylic display stand.

In the past few years, deposits near Issafen, Morocco have begun yielding a new assemblage of Early Cambrian trilobites. This fauna is very diverse and consists mainly of ellipsocephalids, chengkouiids, gigantopygids, holmiids, neltneriids, saukiandids, and the latest fallotaspids. The shale when freshly split is a greenish to slightly yellow color but weathers to a light grey.

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.
