Resumen

In 1BO, one of the outcrops of Bin el Ouidane sites, there are theropod footprints with narrow toemarks that are small in size. The prints, even those from the same trackway, are formed in two superposed levels (from an earlier and later time) of finely laminated sandstones separated by some three centimeters of sediment. The upper level cannot be identified as the tracking surface, given that the structures that accompany the footprints are similar to those of the lower level, which are clearly undertracks. The characteristics of many of them (very narrow toemarks, high divarication, very elongated marks of toe III, width of the footprints and very narrow trackways) are typical of avian ichnites. In this work, such an attribution has been ruled out and it is postulated that the trackmaker is a small theropod dinosaur, from the description and origin of the print structures.
