1.6" Prone Scotoharpes Trilobite - Boudib, Morocco

Here is an nice example of the Harpetida trilobite Scotoharpes sp. from Morocco. 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.
