Resumen
During the 2009´s summer courses (universities Rabat-La Rioja) 6 new pleoichnological es are found in the Bou Guemez river. The previously know Ibaqalliwn-Talsnant sites are located in the close west. All new, and Ibaqualliwn-Talsnant fossil traces, are print over the upper levels of marine limestones from Arganane Formation (Domerian). The likewise Domerian lowermost part continental sediments of the superposed Azilal Formation is placed to 5 m above the ichnites. The litological composition, invertebrate fossil content, and number of ichnological levels is similar in the Assif-n-Bou Guemez-Assif-n-Rbat zone. In spite of the Quaternary aluvial sediments cover, the geological properties are enough to define exactly the same stratigraphic position of the sites. The Arganane Formation dissapear to east part and the new sites are the east end of the Bou Guemez dinosaur footprints outcrops. It is important show the sauropod supremacy in the Bou Guemez zone.
