2.8" Bathyuriscus Fimbiatus Trilobite With Cheeks - Utah

While Bathyuriscus fimbiatus is considered a common trilobite it is exceedingly difficult to find specimens that are not molts and still have their cheeks attached. This is one of those 1 out of 1,000 which still has it's cheeks preserved. This came out of an old collection we recently purchased.

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.
