Copyright © 2016 Cambridge University Press. Southwestern Europe is one of the best regions for characterizing the dinosaur assemblages that prevailed just before the end-Cretaceous extinction. Aiming to better document this scenario, we provide the first evidence of dinosaur skin impressions in the red-beds of the Tremp Formation (southern Pyrenees). The impressions are assigned to sauropods (probably titanosaurians) on the basis of their scale morphology, arrangement and size. They represent a valuable tool for analysing the last occurrences of the sauropod clade before the K-Pg extinction, as they fall within chron C29r (latest Maastrichtian), thus representing some of the last in situ remains of this clade worldwide.
