The Lopingian is the uppermost
series/last
epoch of the
Permian.
It is the last epoch of the
Paleozoic. The Lopingian was preceded by the
Guadalupian and followed by the
Early Triassic.
The Lopingian is often synonymous with the informal terms late Permian or upper Permian.
The name was introduced by

Global Boundary Stratotype Section and Point (GSSP) has been approved, the lower boundary of the earliest stage determines numerical age of an epoch. The GSSP for the
Wuchiapingian has a numerical age of 259.8 ± 0.4 Ma.
Evidence from
Milankovitch cycles suggests that the length of an Earth day during this epoch was approximately 22 hours.
The Lopingian ended with the
Permian–Triassic extinction event.
