7.2" Inflated Parahomalonotus Trilobite - Foum Zguid, Morocco

This is a species not normally seen from the Timrhanrhart Formation, Parahomalonotus calvus. It's quite large at 7" long and very inflated. It displays some compression which is the case with nearly all of the trilobites that come out of the layer. I suspect the head on this specimen maybe a composite from another specimen, but the work is so well done it's difficult to tell if that's the case or it's just some repair work between the head and thorax. A few patches of shell restoration, but nothing too major.

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.
