First Upper Devonian crustacean coprolites:Favreina priman. sp. from northern Morocco

The crustacean coproliteFavreina priman. sp. and its internal structure are described from an upper Frasnian–lowermost Famennian limestone clast of moderately deep water origin, which derived from an Upper Carboniferous conglomerate of the Rif Mountains, northern Morocco. The fecal pellets were produced by early decapods that may be related to the Palaeopalaemonidae. Foraminifers of the stratigraphic marker genusEonodosariaare associated with the coprolite. This is the third report of Paleozoic crustacean coprolites and the first occurrence prior to the Lower Permian.
