Beautiful Basseiarges Trilobite With Partial - Jorf, MoroccoThis is a beautiful, .9" specimen of Basseiarges from Jorf, Morocco. The rock from this locality is extremely hard with an almost glass-like texture making it difficult to prepare. This results in many specimens being “burnt” during preparation and loosing a lot of shell detail. Not this little beauty. This is also a partial specimen, running into a quartz seam in the rock.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.For sale at: https://www.fossilera.com/fossils/9-basseiarges-trilobite-with-partial-jorf-morocco -- source link
