1.75" New Type Of Harpes Trilobite - Ouzina, Morocco
This is a stunning specimen of what maybe a new species of Harpes trilobite from Ouzina, Morocco. This is the first example of the species I have had, and I was told only 4 or 5 of them were found at the location. The preservation, shell color and preparation on this specimen is fantastic. It measures 1.75" long, has a very wide head-shield and it nicely presented on a large piece of limestone.
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.
