1.4" Top Quality, Red Declivolithus Trilobite - Mecissi, Morocco

This is a top quality, 1.4" wide specimen of the Trinucleid trilobite Declivolithus from Morocco. It has a natural, red preservation due to the oxidiation of iron pyrite which had replaced the fossil.

This trilobite has really dramatic cephalic pits along it's "head shield". It's unknown the exact purpose of these pits, they could have had sensory purposes or aided in filter feeding.

An Upper Ordovician (Katian) Trilobite Fauna From the Lower Ktaoua Formation, Morocco

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet with over 25k described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left a excellent fossil record.
