Double, Short Snout Psychopyge Trilobite - Issoumour, Morocco

This is an really nice, natural, double Psychopyge trilobite specimen from the Tazoulait Formation of Morocco. This is the short-snout variety of Psychopyge, which is similar to Psychopyge elegans but has a shorter rostrum. Both speicmens are well prepared will all natural spines. There is a little bit of weathering on the thorax of the smaller specimen, but no restoration.

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.
