Editing Permian (section)

=== Regional stages ===
The Russian Tatarian Stage includes the Lopingian, Capitanian and part of the Wordian, while the underlying Kazanian includes the rest of the Wordian as well as the Roadian.<ref name="Olroyd-2017" /> 

In North America, the Permian is divided into the Wolfcampian (which includes the Nealian and the Lenoxian stages); the Leonardian (Hessian and Cathedralian stages); the Guadalupian; and the Ochoan, corresponding to the Lopingian.<ref>{{cite book |last1=Ross |first1=C.

The [[New Zealand geologic time scale]] divides the Permian into three epochs, Pre-Telfordian (undivided), D'Urville (divided into the Makarewan, Waiitian, and Puruhauan stages), and Aparima (Flettian, Barrettian, Mangapirian, and Telfordian stages). The Pre-Telfordian epoch corresponds approximately to the Asselian, Sakmarian, and Artinskian stages; the D'Urville epoch is roughly contemporary with the Kungurian stage and Guadalupian epoch; and the Aparima epoch is closely contemporary with the Lopingian epoch.<ref>{{cite journal|last1=Cooper |first1= R.
