Аннотация:A rich ichno-assemblage is known from the Upper Devonian (Famennian) Aoufilal Formation ofthe eastern Anti-Atlas in Morocco. Despite its high diversity, only a few trace fossils have been properlydescribed until now. In addition to fish-produced ichnotaxon Undichna detected earlier, resting and walkingtrace fossils of aquatic arthropods (Rusophycus and Diplichnites), walking trackways and feeding areas ofeurypterids (Palmichnium), and rosette-type crustacean or polychaetan feeding burrows (Asterichnus) aredescribed here. All the traces are preserved in positive hyporeliefs on the lower bedding surfaces of a reddishbrownfine-grained sandstone accumulated under shallow-marine conditions. A high diversity, excellentpreservation and frozen state of the paleocommunity despite the absence of body fossils allow us to rate the Aoufilal ichno-assemblage as an ichnofossil Lagerstätte.
