3" Kayserops megaspina Trilobite - Top Quality

This is a scarce Kayserops megaspina trilobite collected at 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.

This specimen is very large for the species at 3" (if outstretched) Just checkout the shell detail and eye facets on this beautifully prepared specimen. Both genal spines have been prepared free of the surrounding rock.

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.
