Abstract

In the Bajocian Hight Atlas calcareous beds of Ifgh (norhern Msemerir) are dinosaur footprints reported to theropod and sauropod ichnites. The described neightbouring sites are in Arhbalou and Taoudaat (at NE) and Adrar-n-Ouglagal (SW),in addition to another non studied in the same Msemerir area. The site has peculiar trackways and footprints of theropod type (semiplantigrades alternated with digitigrades) and irregular groups of sauropod footprints too in some of wich manus only marks are mainly. Among other things its probably that sauropods were swimming and there are evidences in order to say that one of the dinosaurs had semiplantigrade optional gait. Dinosaurs made his traks in an algae laminated bed which is traversed and deformed by their feet. Therefore, although there are so much direct structures, most of the outline footprints are undertracks and not true footprints.
