Pair Of Isoteloides Flexus Trilobites - 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 natural double specimen of the asaphid trilobite (Isoteloides flexus) from the Lower Ordovician, Fillmore Formation in Utah. You have to move a lot of rock to find a good single specimen, so it's quite hard to get multiples, especially multiples with good preservation. While on occasion these trilobites can get quite large, these are about average size for the ones we find at .85" and .45"

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.
