Danube-Gunz interglacial age of about 900,000 to 940,000 years. There are however indications that the Uhlenberg Profile may still be placed within the Pliocene, and it would thus not correlate with the Danube-Gunz interglacial. Also uncertain is its association with the North German classification because of its position in the underlying stratum of the Gunz it could correspond to the Bavelian or the Waalian interglacial. The Danube-Gunz corresponds at least in part to the Swiss Deckenschotter glaciations. Danube-Gunz interglacial The Danube-Gunz interglacial (), Danube-Gunz warm period ("Donau-Günz-Warmzeit"), often just Danube-Gunz, or also Uhlenberg interglacial ("Uhlenberg-Warmzeit") is the second-oldest named warm period of
