1.33" Wide, Enrolled Asaphus Minor Trilobite - Russia

This is a 1.33" wide, enrolled Asaphus minor trilobite. Asaphus minor is one of the rarer of the 30+ Asaphus species from the area, in fact I think it's the first example we have had. This cute trilobite would be just over 2" long if outstretched.

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.
