Abstract Distinctive facies change and magnetic susceptibility across the neritic Rauchkofel Limestone (Central Carnic Alps) document specific sea-level fluctuations that are related to the Lochkov–Prag Event. This is supported by a positive shift in the carbon isotope signal of about 1.5‰ and a distinct decline in conodont biodiversity during the late Lochkovian. A transgressive interval during the late Lochkovian is followed by a regressive phase indicated by an eye-catching megaclast horizon of early Pragian age. Some of the boulders within that horizon reach up to 10 m in diameter. A model explaining regional depositional patterns is provided.
