Geological Society of America Bulletin, 1965
The Oligocene-Miocene boundary has not been clearly defined, and its stratigraphic position in Europe is controversial. Because it is a boundary between international stratigraphic units, it should be defined by international agreement in an area with suitable fossils, preferably with planktonic foraminifera, at a horizon that can be identified widely ...

International Geology Review, 1963
Review of the origin of the Oligocene Series and particularly of the Lattorfian Stage. Author concludes that Lattorfian is equivalent to upper Eocene and that base of Oligocene should be placed at base of the Rupelian Stage and its correlatives. A review of the Oligocene divisions and faunas of the North Caucasus, Crimea, South Ukraine, Mangyshlak ...
