MacPhee, and U. F. J. Pardiñas. 2021. New radiometric 40Ar–39Ar dates and faunistic analyses refine evolutionary dynamics of Neogene vertebrate assemblages in southern South America. Scientific Reports 2021(11):9830 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 8 timescales which overlap this one. show

• Cenozoic Subepochs: Late Pliocene subepoch, Early Pliocene subepoch
• European Faunal Units: Villanyian subage, Ruscinian subage
• European Faunal Zones: MN 16 zone, MN 15 zone
• Neogene Mammal Ages of China: Yushean age
