1.5" Spiny Cyphaspides Ammari Trilobite - Rare Species

This is a beautifully prepared example of a rare, Cyphaspides ammari trilobite. It's partially enrolled but would be about 1.5" long if outstretched. While we've had many examples of other Cyphaspides species from the localities near Jorf, I think this is the first example of Cyphaspides ammari we've been able to offer.

This particular species was just described in 2019, a link to the paper is below.

Species of the Devonian aulacopleurid trilobite Cyphaspides from southeastern Morocco

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.
