Paleoichnological explorations in the west part of the Iouaridène syncline (Hight Atlas. Morocco). Inventory of the sites and ichnite number

The Iouaridène syncline is a is famous palaeontological site among the ichnologists for several reasons: i) the time of the site is known - the first footprint paper were published in 1937; ii) the discovery of the sauropod trackway Breviparopus, Dutuit and Ouazzou, 1980 used as narrow gauge morphotipe by Farlow (1992); iii) the succesive discussions about the age of the “red beds” where the ichnites were found, and in consequence, the variations in the footprint age attributions; and iv) the discussion about the swimmer dinosaurs in manus-only sauropod trackways. The exploration on the area and the bibliographical review have allowed to verify many of the former suppositions and to adjust the age of the mentioned sauropod trackway, fact of great importancy in the dinosaur palaeoichnology
