7.2" Parahomalonotus Trilobite With Friend - Foum Zguid, Morocco

Parahomalonotus Trilobite With Friend - Foum Zguid, Morocco #71261

This is a species not normally seen from the Timrhanrhart Formation, Parahomalonotus calvus. The larger of the two specimens is a huge at 7.2" long and very inflated. Both trilobites display some compression which is the case with nearly all of the trilobites that come out of the layer. There is a bit of disarticulation near the head of the larger specimen with the last segment pushed up underneath the head.

Neither specimen has any compositing, and just some minor shell restoration along the repaired cracks. There is a repaired crack between the two specimens and while I think there is a chance the two trilobites have been composited next to each other on the plate, things seem to align correctly.

About Trilobites

Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
