Lujanian

The Lujanian age is a South American land mammal age within the Pleistocene and Holocene epochs of the Quaternary, from 0.4–0.011 Ma or 400–11 kya.

== Chronology == The Lujanian age follows the Ensenadan age, and precedes the Platan age. The age is usually divided into the middle Pleistocene Bonaerian substage, which ends at about 130,000 years, and the Lujanian 'sensus stricto' substage, which lasts from about 130,000 years into the early Holocene. As the approximate boundary between the Ensenadan and Lujanian has been historically undetermined, a "Belgranian" stage has been used to bridge the two faunal stages, although more recent research does not support this. The Lujanian age overlaps chronologically with the North American Irvingtonian and Rancholabrean faunal stages.
