1.9" Multi-Colored Phacops Araw Trilobite
This is a 1.5" long (if outstretched), outstretched specimen of Phacops araw, a fairly rare species of phacopid from Morocco. It has a distinctive bulging glabella covered in large tubercles. This trilobite has a naturally, multi-toned shell coloration which is quite beautiful. Only about 1% restoration along the repaired crack.
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.
