“…Continental carbonates are rich in palaeoclimatic, palaeoenvironmental and palaeontological information; they are found within all types of land‐based sedimentary systems all over the world (Alonso‐Zarza & Wright, ; Gierlowski‐Kordesch, ; Jones & Renaut, ; Gierlowski‐Kordesch et al ., ), especially in extensional basins (Alonso‐Zarza et al ., ). Reports on continental carbonate deposits in the geological record in South America are scarce and belong mainly to Jurassic and Cretaceous deposits (Bertani & Carozzi, ; Suárez & Bell, ; Rouchy et al ., ; Camoin et al ., ; Cabaleri & Armella, , ; Gómez‐Pérez, ; Tunik, ; Beraldi‐Campesi et al ., ; Cabaleri et al ., , ; Cabaleri & Benavente, ). Reports of Triassic continental carbonates, however, have been non‐existent until now.…”
