1.85" 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 1.85" long asaphid trilobite (Isoteloides flexus) from the Lower Ordovician, Fillmore Formation in Utah. The vast majority of Isoteloides we find are under an inch long, so this one is pretty good sized. There is some compression but the shell in generally well preserved and both cheeks are in place.

About Trilobites
Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
