Bartonian

  • 1. An age (40.4–37.2 Ma ago) in the Middle Eocene, preceded by the Lutetian, followed by the Priabonian (Int. Commission on Stratigraphy, 2004).

    2. The name of the corresponding European stage, which is roughly contemporaneous with most of the upper Narizian (N. America), upper Bortonian and Kaiatan (New Zealand), and part of the Aldingan (Australia). It was originally considered to be a lateral equivalent of the Priabonian stage (Upper Eocene). (The name should not be confused with Bortonian.)
