1 The final age in the Early Permian Epoch, preceded by the Artinskian, followed by the Roadian (Late Permian), and dated at 275.6–270.6 Ma (Int. Commission on Stratigraphy, 2004).
2 The name of the corresponding eastern European stage, which is roughly contemporaneous with the Weissliegende (western Europe), upper Leonardian (N. America), and Tae Weian (New Zealand). Boundary and correlation uncertainties have led to some rocks being assigned to either the Artinskian or Ufimian Stages.
