Two Foulonia Trilobites with a Cephalopod - Fezouata Formation

This is a cluster of two Foulonia trilobites preserved alongside a partial Asaphellus trilobite and a cephalopod, collected from the Fezouata Formation of Morocco. Trilobites from this locality are often found in lines, which has sometimes been interpreted as fossilized migratory behavior. We tend to think it's more likely the orientation is due to currents sweeping the trilobites into wave depressions in the ocean floor. A paper was published a couple years back, describing similar fossils from this same locality.

480-million-year-old trilobite ‘traffic jams’ may reveal ancient migratory behavior

The entire piece measures 10.1 x 5.65" and the largest trilobite is 2.3" in length. Preparation is very good and there is approximately 3-4% restoration along repaired cracks. It comes with an acrylic display stand.

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.
