1.05" Acastoides Trilobite With Nice Eyes

 
 
 
 
 
 
 
This is a nice, 1.05" long example of the small phacopid trilobite Acastoides zguilmensis from the Timrhanrhart Formation south of Foum Zguid, Morocco.

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.
