35.9 - 28.9 Ma

The definition of this interval in the timescale South American Land Mammal Ages is taken from the following source:

• J. J. Flynn and C. C. Swisher, III. 1995. Cenozoic South American Land Mammal Ages: correlation to global geochronology. Geochronology Time Scales and Global Stratigraphic Correlation, SEPM Special Publication 54:317-333 view

The top and bottom ages have been interpolated based on the differences between the ages for international timescale boundaries quoted in the source and the currently accepted ages for those boundaries.

There are intervals in 7 timescales which overlap this one. show

• International Chronostratigraphic Timescale: Priabonian age, Oligocene epoch, Eocene epoch, Rupelian age
