2.8" Excellent Kayserops megaspina Trilobite - Bou Lachrhal, Morocco

This is a rare Kayserops megaspina from Bou Lachrhal, Morocco. In the past this trilobite has often been referred to as “Comura cometa", but it actually bears few similarities with the genus Comura. The head on this specimen is tucked but it would be about 2.8" long if outstretched. Excellent preservation and shell quality with the genal spines prepared free-standing.

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.
