Aptian
From Wikipedia, the free encyclopedia
Aptian stage is a faunal stage of the Early Cretaceous epoch in the geologic timescale, that extends from 125.0 ± 1.0 Ma to 112.0 ± 1.0 Ma (million years ago), approximately. The Aptian stage succeeds the Barremian stage and precedes the Albian stage, all in the same epoch.
