Zlichovaspis & Crotalocephalina Trilobites - Stunning Preparation

This is a stunning association of two different types of trilobites from the Lhandar Formation near Atchana, Morocco. There is a 3" long Zlichovaspis rugosa naturally associated with a similarly sized Crotalocephalina gibbus. They have been carefully prepared to remove the hard limestone surrounding the fossils leaving them in an aesthetic pose.

There is a small amount of shell restoration on the back of the head and first few axial rings of the Crotalocephalina.

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.
