Two Ordovician Trilobite (Ampyxina) Fossils - Missouri
These are two prone specimens of the Ordovician trilobite Ampyxina bellatula. These trilobites were collected from the Maquoketa Formation of Pike County, Missouri. The largest trilobite is .34" long.
The trilobites have been color enhanced so they stand up better against the surface of the rock.

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.
