5" Spiny Psychopyge Trilobite - Issoumour, Morocco

This is a large, 5" long, spiny Psychopyge elegans trilobite from the Tazoulait Formation at Issoumour, Morocco. Both the preservation and preparation on this specimen is excellent. All the spines have been prepared free-standing including the long genal spines and there is nice eye facet preservation in both eyes. One of the better examples of the species that we have had to offer.

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.
