Three Lonchodomas (Ampyx) Trilobites - Morocco
This is three orangish, Lonchodomas sp. trilobites from the Lower Ordovician deposits in the Zagora area of Morocco. The longest trilobite is 1.9" long from tip of the glabellar (nose) spine to the end of the genal spines. The natural, orange/red coloration is caused by the oxidization of iron pyrite which originally preserved the trilobites. There maybe some restoration or color enhancement on the ends of the genal spines as they tend to be faintly preserved.
Lonchodomas, formerly Ampyx has a distinctive, elongated rostrum and sweeping genal spines, which may have both helped to deter predators as well as providing more surface area to keep it on top of the mud.

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.
