Duchesnean

The Duchesnean North American Stage on the geologic timescale is a North American Land Mammal Age (NALMA), with an age from 42 to 38 million years BP, representing 4 million years[1]. It falls within the Eocene epoch. The Duchesnean is preceded by the Uintan and followed by the Chadronian NALMA.

The Duchesnean falls within the Bartonian age of the geologic timescale.
