6.2" Eudolalites with Selenopeltis Trilobites and a Machaeridian

This is an interesting association from the Upper Tiouririne Formation of Morocco. On this 15.7" wide slab of limestone there is a large, dalmanitid (Eudolalites maiderensis) trilobite along with a pair of Selenopeltis trilobites, an unidentified arthropod, and an armoured annelid worm of the genus Plumulites. The Eudolalites is huge at 6.2" long and the larger Selenopeltis is 4.5". Restoration is pretty minimal along a repaired crack in the slab.

Plumulites is a rare, extinct genus of armored, segmented annelid worms (machaeridians) that existed from the Ordovician period to the Early Triassic period (480 - 250 MYA). They are relatives of the modern-day earthworm, leech, and bristleworm. Plumulites fossils are extremely rare, with less than ten documented fossils found.

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 currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
