1.7" Thysanopeltis Trilobite - Issoumour, Morocco

 
This is a 2" long example of the Middle Devonian trilobite Thysanopeltis speciosa from Mount Issoumour, Morocco. What is so distinctive about this trilobite is the fringe of pygidial (tail) spines. There is some restoration to the left hand side of the thorax along the repaired crack, about 2-3% in total.

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.
