Era: Paleozoic

Stage: Tremadocian (485.4 - 477.7 Ma)

Location: Beni Zouli, Zagora Province (Morocco)

Description: Unique piece from the Fezouata Formation. Scientists believe that trilobites migrated in groups along the seabed when they were buried and that the way they kept in physical contact could be either through their long antennae, or through pheromones, by chemical communication, like today's ants. This specimen is, without a doubt, a piece worthy of study.
