Besides bones, fossil tracks and trackways are important sources of knowledge about dinosaur palaeobiology. Here, we report three new tracksites from two different synclines in the Imilchil area, Central High Atlas, Morocco. The preserved fluvial deposits levels Isli Formation (Early Bathonian-?Upper Jurassic), contain impressions made by sauropods, theropods ornithopods, as well that might represent bird-like non-avian theropod dinosaurs. In addition to traditional field measurements, three-dimensional digital models track sites were created using photogrammetry. These add rich faunal ichnoassemblage already recorded Atlas Mountains North Africa, which is considerably richer than contemporaneous body record, also provide data on dinosaurs-substrate interactions.

This paper presents the study of 14 new sites with theropod footprints in Imilchil. The focuses on ichnotaxonomic and extramorphological characteristics footprints, analysis their trackways, correlation descriptions published tridactil footprints. objective has been to provide a comparative view ichnites relationship between substrate footprint (in interval its formation current state) data. distribution true or real (including stamps deformed footprints), undertracks, subtracks, eroded is introduced, variation morphological characters due preservation processes analyzed. An exposition measurements trackways also made, comparing them data obtained two other large studied known by team (La Rioja Iouaridène). numerical confirm generality some previous little-known observations repetition distributions related metric dinosaur trackways.
