.71" Basseiarges Trilobite - Jorf, Morocco

This is an nice, .71" 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. The shell is actually translucent, so it is taking on the reddish-brown color of the rock below.

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: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
