%X The Upper Triassic carbonates of the Kr¨ª na Unit in the eastern part of the Kriv¨¢nska Mal¨¢ Fatra Mts contain the unique siliciclastic interbeds. They are developed between the Ramsau Dolomite Formation and the Hauptdolomite Formation, and comprise alternating dark grey shales and pale grey dolomites. Such a shaly-dolomite formation is unknown from the Upper Triassic formations of the Kr¨ª na Unit, which makes it possible to define a new lithostratigraphic unit (Tr inovo Formation). The Ramsau Dolomites beneath the Tr inovo Formation contain microfauna of Carnian foraminifers. Therefore, the Carnian age has also been constrained for the Tr inovo Formation, which by the reduced carbonate productivity and enhanced terrigenous influx could be related to the Reingraben Event. This event related to the "Carnian Pluvial Episode" is also inferred in the Tr inovo Formation by the presence of lingulide brachiopods (Lingularia) and spinicaudatan crustaceans (Euestheria). This fauna provides evidence of not fully marine conditions of the Tr inovo Formation, influenced by continental freshwater influx and humid climate.
