Three Trilobite (Kainops & Paciphacops) Fossils - Oklahoma

This is a 4.1 x 2.8" piece of limestone from the Haragan Formation of Oklahoma with three phacopid trilobite fossils. The prone specimen is Kainops raymondi, along with a pair of smaller Paciphacops cambelli. While these two species look very similar, Kainops has larger eyes, and more eye facets than Paciphacops. The piece has been nicely prepared with air abrasives under microscope to expose the detailed fossils.

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.
