Huge, 1.85" Cyphaspides Trilobite - Jorf, Morocco

This is a huge, 1.85" long specimen of a long-spined Cyphaspides trilobite Jorf, Morocco. This is substantially larger than most specimens that are closer to an inch in length. It's nicely inflated with good preparation and only about 1-2% restoration. Both genal spines have been prepared free-standing.

The rock from this location is partially metamorphised giving the shell of the trilobites a translucent, glass-like texture but making them extremely difficult and time consuming to prepare. This incredible specimen was prepared by one of the very best preparators in the world and the quality of the work shows.

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.
