New sauropod tracks from the Yacoraite Formation (Maastrichtian–Danian), Valle del Tonco tracksite, Salta, northwestern Argentina

Purpose A relative long sauropod trackway and hundreds of varied indeterminate dinosaur tracks, many of them probably related to ornitischians, were found many years ago in the Valle del Tonco tracksite (Salta, northwestern Argentina). This sauropod trackway is now described and analyzed in an updated context.
