The Late Pleistocene saw the extinction of many mammals weighing more than 40 kilograms (88 lb), including around 80% of mammals over 1 tonne. The proportion of megafauna extinctions is progressively larger the further the human migratory distance from Africa, with the highest extinction rates in Australia, and North and South America. [11]
The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c ...
The indigenous fauna of the West Indies collapsed in the Late Quaternary, with the rate of extinction for terrestrial mammals approaching 79-84%, one of the highest in the world. However, in stark contrast to the American continent, radiocarbon dating indicates that mammals survived the end of the Pleistocene with no apparent, or minimal losses ...
Late eruptions of the Siberian Traps Griesbachian-Dienerian boundary-event 252 Late eruptions of the Siberian Traps [22] Permian: Permian–Triassic extinction event: 252 Ma Large igneous province (LIP) eruptions [23] from the Siberian Traps, [24] an impact event (the Wilkes Land Crater), [25] an Anoxic event, [26] an Ice age, [27] or other ...
Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Late Pleistocene or Early Holocene – and before recorded history, specifically before they could be studied alive by ornithological science. They had died out before the period of global scientific exploration that started in the late 15th ...
The Late Pleistocene witnessed the spread of modern humans outside of Africa as well as the extinction of all other human species. Humans also spread to the Australian continent and the Americas for the first time, co-incident with the extinction of most large-bodied animals in these regions.
Mass extinctions are characterized by the loss of at least 75% of species within a geologically short period of time (i.e., less than 2 million years). [18] [51] The Holocene extinction is also known as the "sixth extinction", as it is possibly the sixth mass extinction event, after the Ordovician–Silurian extinction events, the Late Devonian extinction, the Permian–Triassic extinction ...
Late Pleistocene −11.8 N/A This Arctodus individual had the strongest δ 13 C value of its local fauna. Arctodus' carbon isotope value was closest to values from the tapir and Hemiauchenia. [31] Natural Trap Cave, Wyoming Late Pleistocene -13.1 N/A The Natural Trap specimens have the lowest δ 13 C of the Pleistocene fauna.
