Extinctions in North America were concentrated at the end of the Late Pleistocene, around 13,800–11,400 years Before Present, which were coincident with the onset of the Younger Dryas cooling period, as well as the emergence of the hunter-gatherer Clovis culture.
2 cze 2020 · Hence, these data suggest that human hunting of large mammals, likely together with climate change at the end of the Pleistocene, led to the extinction of megafauna in North America.
16 lut 2021 · The disappearance of many North American megafauna at the end of the Pleistocene is a contentious topic. While the proposed causes for megafaunal extinction are varied, most researchers...
24 lis 2023 · The worldwide extinction of megafauna during the Late Pleistocene and Early Holocene is evident from the fossil record, with dominant theories suggesting a climate, human or combined impact cause.
1 gru 2023 · While late-Pleistocene extinctions of Ice Age megafauna in North America occurred throughout the Younger Dryas stadial, a new study from researchers at Rancho La Brea pinpoints a stark and dramatic finality that befell the Rancholabrean megafauna of Southern California before this, during the Bolling-Allerod Warming.
9 lis 2020 · As the Pleistocene came to an end in North America, 38 genera of mammals vanished (Table 1). The majority are designated as megafauna, with a body mass over ∼45 kg, including several proboscideans (mammoth, mastodon, gomphothere) weighing more than 4,500 kg.
14 lut 2023 · Thus, it is probable that the widespread extinction of herbivorous megafauna in the late Pleistocene influenced atmospheric gas exchange and global climate. Several authors have calculated the enteric production of methane by megafauna at the terminal Pleistocene.
