16 lut 2021 · Near the end of the Pleistocene (~11,700 years before present [BP]) at least 37 genera of megafauna (~80%) had disappeared from North America, and by as early as the late eighteenth century...
2 cze 2020 · Large-scale changes in global climate at the end of the Pleistocene significantly impacted ecosystems across North America.
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...
14 lut 2023 · The extinctions occurring during the late Pleistocene are unusual in this regard, because they were strongly size-selective and targeted exclusively large-bodied animals (i.e., megafauna, >1 ton) and disproportionately, large-bodied herbivores.
9 lis 2020 · As the Pleistocene came to an end in North America, 38 genera of mammals vanished . 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.
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.
23 lip 2015 · The mechanisms of Late Pleistocene megafauna extinctions remain fiercely contested, with human impact or climate change cited as principal drivers. We compared ancient DNA and radiocarbon data from 31 detailed time series of regional megafaunal extinctions and replacements over the past 56,000 years with standard and new combined records of ...
