Chapadmalalan
The Chapadmalalan ('Chapalmalan') age is a period of geologic time (~5.0–3.3 Ma) in the Pliocene epoch of the Neogene, used more specifically in the South American Land Mammal Ages.
The Chapadmalalan follows the Montehermosan age and precedes the Marplatan age. The source locality for the Chapadmalalan is the Chapadmalal Formation near Chapadmalal, Buenos Aires Province, Argentina.
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.
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.
