Bargain, 2.25" Spiny Ceratonurus Trilobite

 
 
 
 
This is one of the more unusual of the spiny trilobites from Morocco, Ceratonurus. It is good sized for the species at 2.25" long and many of the spines have been prepared free standing.

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.
