- Extinct south american megafauna The megafauna extinction in South America was one of the most profound events, with the loss of 50 genera (~ 83%). South America suffered among the worst losses of the continents, with around 83% of its megafauna going extinct. We refine the chronology of Quaternary Megafauna Extinction in South America. However, here, the authors show that megafaunal extinctions do correspond to the spread of hunting tools and human population shifts. South America was one of the most severely impacted continents losing over eighty percent of all its species of mammals with an average body weight exceeding forty four kilograms. New dates indicate a protracted extinction event in the Pampas (10 to 13 BP). Across the last ~50,000 years (the late Quaternary) terrestrial vertebrate faunas have experienced severe losses of large species (megafauna), with most extinctions occurring in the Late Pleistocene and Early to Middle Holocene. [10] These extinctions postdate the arrival of modern humans in South America around 15,000 years ago. Human arrival in South America predated the extinction of regional megafauna by a substantial margin, which has suggested a different cause for the extinctions. Here we analyze the temporal dynamic and spatial distribution of South American megafauna and fluted (Fishtail) projectile points to evaluate the role of humans in Pleistocene extinctions. The dates suggest a more accurate window of extinction and first human occupation. This is due to the fact that the process of human colonizing was. This is due to the fact that the process of human colonizing was This is a list of South American animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [A] and continues to the present day. Three orders disappeared (Notoungulat a, Proboscidea, Litopterna), as did all Human arrival in South America predated the extinction of regional megafauna by a substantial margin, which has suggested a different cause for the extinctions. Debate on the causes has been ongoing for over 200 years, intensifying from the 1960s onward. However, here, the authors Regional variation is important in the evaluation of the human role in the extinction of megafauna in South America.
