The Chapadmalalan age is a period of geologic time in the Pliocene epoch of the Neogene, used more specifically in the South American Land Mammal Ages.

Fauna

'Lower Chapadmalalan'

The Chapadmalalan age was previously divided into a lower and upper stage, with the lower stage hosting the "Neocavia depressidens" biozone. However, this was revised into a single biozone.

Biozone

Previously characterizing the Upper Chapadmalalan, the taxa Paraglyptodon chapadmalensis previously defined the biozone of the entire Chapadmalalan age, however revisions found P. chapadmalensis to be a juvenile of Glyptodon.
