We report here on the first tetrapod tracks from the Triassic ofthe Nurra region (north-western Sardinia, Italy). The specimens werefound on sandstone blocks used to build a fence limiting a seasonalcamping, in the coastal area north of Capo Caccia promontory.Lithologic and petrographic features allowed an assignment of thetrack-bearing blocks to the middle-upper portion of the Anisian(Middle Triassic) Arenarie di Cala Viola (?Buntsandstein?). Footprintsare attributed to the ichnotaxa Rhynchosauroides and Rotodactylus,two common ichnotaxa of late Early Triassic and Middle Triassicichnofaunas of Europe and United States, commonly referred in theliterature to neodiapsid and archosaur producers, respectively.
