1.2" Cambrian (Kingaspidoides?) Trilobite - Tinjdad, Morocco
This is only the third example of this rare Middle Cambrian trilobite I've seen from the Jebel Wawrmast Formation near Tinjdad, Morocco. I'm not 100% sure on the ID but it does appear to be a Kingaspidoides with it's distinctive occipital spine, and long curved spine off of the last segment. The orange coloration is natural and due to the oxidization of iron pyrite. Definitely one for the species collector.
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.
