1.55" Wide, Enrolled Pedinopariops Trilobite - Mrakib, Morocco
This is a 1.55" wide, enrolled specimen of Pedinopariops (Hypsipariops) vagabundus from Mrakib, Morocco. It has been entirely removed from the surrounding limestone. It's almost perfectly enrolled with nice eye facet preservation in the left eye, though there is some shell restoration on the right side of the head and thorax.
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 currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
