Thysanopeltella (Thysanopeltis) Trilobite & Two Basseiarge - Jorf

This is an association of an unusual Thysanopeltella (Thysanopeltis) and two Basseiarges mellishae trilobites from Jorf, Morocco. The Thysanopeltella is 2.1" long and likely represents an undescribed species. Both Basseiarges (one ventral, one dorsal) are about .9" in length. The shell is actually translucent, so it is taking on the reddish color of the rock below. Restoration is about 4-5% on the Thysanopeltella, one patch on the right side of the tail and then a number of very small patches of shell restoration spread over the surface of the trilobite.

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.
