Bargain, 1.8" Scotoharpes Trilobite - Boudib, Morocco

 
 
 
Here is a Scotoharpes trilobite from Boudib, Morocco on the NE side of Jebel Issoumour. It has a very dramatic "head shield" which is often interpreted as a mechanism to help it stay on top of a soft ocean floor. This preglabellar ring (head shield) is covered in many sensory pits which may have held hairlike features when the trilobite was alive.

The tail is likely curled under the body and there is about 5% shell restoration, all on the right side the head/shield.

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.
