English abstract:
The dinosaur ichnological research in the Upper Jurassic lacustrine
sediments of the Iouaridène syncline provide data of interest. One of
them includes the discovery of gigantic digitigrade theropod
footprints, with a not described size. The exposures of ichnitic
levels are continuous in the zone and the continuity of stratigraphic
beds permits the good correlation. All sites are directly linked,
except one of them that are separated by a cover of quaternary glacis
sediments. Inside the work area, that includes the half of the
syncline, the giant footprints occupy a limited section that extends
in the same direction of these footprints. The spatial situation
allows us to propose that the gigantic footprints of every bed belong
to the same trackway, with a maximum length 2000 m. The direct and
indirect footprint structures are distinctive from each to other
trackway. However these are not the only footprints discovered;
between and inside the sites, there are many smaller theropod and some
ornithopod and sauropod prints. This shows that, at least three giant
theropod dinosaurs lived in the same site with the smaller theropods
being the last most prominent. After a comparative study it is
proposed that two of the three gigantic theropod trackways and the
digitigrade footprints described in this paper, are the largest
discovered yet in the world.
