Detailed, 1.85" Metacanthina Trilobite - Lghaft, Morocco

This is a 1.85" long specimen of Metacanthina issoumourensis often referred to as an "Asteropyge" or “Kayserops”. It was quarried near Lghaft, Morocco, and has exceptional eye facet preservation in both eyes. It's laid out nice and prone with good preparation. There is about 3% shell restoration over the left eye and the very tip of the right genal spine.

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.
