1.85" Wide, Enrolled Pedinopariops Trilobite - Mrakib, Morocco
This is a 1.85" wide, partially enrolled specimen of Pedinopariops (Hypsipariops) vagabundus from Mrakib, Morocco. It has been entirely removed from the surrounding limestone. It's almost perfectly enrolled with good eye facets in the right eye but there is some shell weathering to the left side of the head.
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.
