.45" Enrolled Isoteloides Flexus Trilobite - Fillmore Formation, Utah

Here is a new offering from a lease we just recently acquired in Utah. While Cambrian trilobites are well known from Utah, several formations also contain a very diverse fauna of Ordovician trilobites, they are just rarely collected.

This is a small, enrolled Isoteloides flexus from the Fillmore Formation in the Southern House Range of Utah. It's pretty unusual to find them enrolled like this.

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.
