1.95" Metacanthina Trilobite - Lghaft, Morocco

Metacanthina Trilobite - Lghaft, Morocco #125091

This is a 1.95" long, prone specimen of Metacanthina issoumourensis often referred to as an "Asteropyge" or “Kayserops”. It was quarried near Lghaft, Morocco, and has nice eye facet preservation in both eyes. At just under 2" long it's quite large for the species and a really nice example.

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: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
