Please note: While we typically ship out material within 2 business days there will be a delay of approximately 2-3 days before we can ship this specimen. It's part of a lot of material currently in transit back to our primary shipping warehouse.
This is a superbly prepared Leonaspis from Mrakib, Morocco. The preparation is top notch, having been done by one of the best preparators in the world and the rock has been left natural, free of tools marks. Even the tiny rows of spines are preserved on the segments, a feature you almost never see on the trilobites, because they are air abraded away.
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.
