The heteromorph ammonite Nostoceras (Nostoceras) hyatti is described for the first time from the Piesting Formation (Gosau Group; Upper retaceous) at Grunbach along the eastern margin of the Northern Calcareous Alps, Lower Austria. This record significantly extends the geographic range of this late Campanian marker species; it was not previously known from the Alpine Cretaceous. Moreover, it corroborates earlier age assignments as late Campanian of the (lower) part of the Piesting Formation. A matrix sample taken from the specimen studied has yielded taxa whose range covers zones CC20 to CC23, or UC 15[^tp] to UC18, of the standard nannofossil zonation.
