2.4" Rare Kayserops megaspina (Comura cometa)

This is a rare Kayserops megaspina from Oued Ghris, Morocco. In the past this trilobite has often been referred to as “Comura cometa", but it actually bears few similarities with the genus Comura. At 2.4" long this is about average size of the species and the preparation is pretty good. Both of the eyes have really good eye facet preservation. There is some shell restoration, probably about 3-5%. The tip of the left genal spine is restored, there is some restoration on the right side of the head, cracks through the thorax and the tips two tail spines.

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.
