These periods are referred to as ages, stages, or intervals and were established using geographic place names where fossil materials where obtained.
2-658: 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 . 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 . The latter Lujanian stage overlaps chronologically with
