Line of Six Migrating Trilobites (Lonchodomas) Trilobites - Morocco
This is a really cool fossil. It is a line of six Lonchodomas trilobites nose to tail that are believed to be caught during a migration. A paper was published last year, describing similar fossils from this same locality.
480-million-year-old trilobite ‘traffic jams’ may reveal ancient migratory behavior
The trilobites measure 2 to 2.5" long (including spines).
Lonchodomas, formerly Ampyx, has a distinctive, elongated rostrum and sweeping genal spines, which may have both helped to deter predators as well as providing more surface area to keep it on top of the mud.

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.
