Lujanian
From Wikipedia, the free encyclopedia
Period of geologic time (0.8–0.011 Ma or 800–11 tya) within the Pleistocene and Holocene epochs
The Lujanian age is a South American land mammal age within the Pleistocene and Holocene epochs of the Neogene, from 0.8–0.011 Ma or 800–11 tya. 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 and cingulates such as glyptodonts and the armadillo-like Pachyarmatherium .
