Two Nice Leonaspis Trilobites - Foum Zguid, Morocco

Here is a two naturally associated and nicely prepared, spiny Leonaspis trilobites from Foum Zguid, Morocco. The dramatic spines are well preserved, you can see the small stalk eyes poking up above it's head. The shell is in much better shape and more detailed than most specimens from Morocco, thanks to good preparation.

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.
