- Abstract
The heteromorph ammonite Nostoceras (Nostoceras) hyatti is described for the first time from the Piesting Formation (Gosau Group; Upper Cretaceous) at Grünbach 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 15tp to UC18, of the standard nannofossil zonation.
