2.3" Crotalocephalus (“Cyrtometopus”) Trilobite - Scarce Species

This is a fairly rare species of Crotalocephalus from the Middle Devonian of Morocco. It has a pair of distinctive projections coming out of the front of it's cephalon. In the past it's been labeled as Cyrtometopus but it's most likely a species of the Crotalocephalus genus. It is arched but would be about 2.3" long if outstretched. The genal spines have been prepared free of the surrounding limestone.

One of the nicest examples of the species that I have seen.

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: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
