1.55" Trinucleid Trilobite (Declivolithus) - Mecissi, Morocco
This is a 1.55" wide specimen of the Trinucleid trilobite Declivolithus from Morocco. It has natural orange preservation due to the oxidation of iron pyrite which had replaced the fossil. The trilobite has excellent detail and comes with an acrylic display stand.
This trilobite has really dramatic cephalic pits along its "head shield". The exact purpose of these pits is unknown, but theories are that they could have had sensory purposes or aided in filter feeding.

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.
