Lujanian

The Lujanian age is a period of geologic time (0.8–0.011 Ma or 800–11 tya) within the Pleistocene and Holocene epochs of the Neogene used more specifically with South American land mammal ages. It follows the Ensenadan.[1] The age is usually divided into the middle Pleistocene Bonaerian stage, which ends at about 130,000 years, and the Lujanian, which lasts from about 130,000 years into the early Holocene.[2] The latter Lujanian stage overlaps chronologically with the North American Irvingtonian and Rancholabrean.

Fauna include ground sloths, litopterns, short-faced bears, South American horse Amerhippus, cingulates such as glyptodonts and the armadillo-like Pachyarmatherium, and others.
