1" Metacanthina (Asteropyge) Trilobite - Great Detail

This is a detailed specimen of Metacanthina issoumourensis often referred to as an "Asteropyge" or “Kayserops”. It's nicely prepared and displays very aesthetically on a sculpted piece of limestone. Great eye facet preservation on this specimen. It's 1" long which is small for the species but the preparation is very nice, with clear eye facets. The genal spines have been prepared of the surrounding limestone.

The tiny occipital spine has been restored and there are a few shell touchups along the repaired cracks.

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.
