Abstract
Four large limestone blocks with dinosaur footprints have been discovered in a large landslide situated in the Sarca Valley (northeast Italy). The trampled sediments have been ascribed to the upper part (Pliensbachian) of the Lower Jurassic Calcari Grigi Formation, which in the Sarca Valley consists of oolitic‐bioclastic limestones. These carbonates were originally deposited on the western margin of the Trento Platform, a paleogeographic structural high that was located in the northern tropical belt at the westernmost end of Tethys. Several footprints form trackways of quadrupedal dinosaurs. The data suggest the presence, within the ichnoassociation, of possible prosauropods and basal Thyrephora. This inference is consistent with the chronological and geographical distribution of both prosauropods and Thyreophora.
