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