The Holocene is a geologic epoch that follows directly after the Pleistocene. Continental motions due to plate tectonics are less than a kilometre over a span of only 10,000 years. However, ice melt caused world sea levels to rise about 35 m (115 ft) in the early part of the Holocene and another 30 m in the later part of the Holocene.
The IUGS has yet to approve a type section, Global Boundary Stratotype Section and Point (GSSP), for the upper Pleistocene/Holocene boundary (i.e. the upper boundary). The proposed section is the North Greenland Ice Core Project ice core 75° 06' N 42° 18' W. [ 17 ] The lower boundary of the Pleistocene Series is formally defined ...
Holocene climatic optimum, or Atlantic in northern Europe (B-S) 6200: 8.2-kiloyear event cold 5000–4100: Older Peron warm and wet, global sea levels were 2.5 to 4 meters (8 to 13 feet) higher than the twentieth-century average 3900: 5.9 kiloyear event dry and cold. 3500
The current interglacial is known as the Holocene epoch. [1] Based on climate proxies , paleoclimatologists study the different climate states originating from glaciation. Known ice ages
Most recent remains dated to the early Holocene. [19] Spermophilus severskensis: Desna River region Highly specialised for grazing, with the narrowest range of all Pleistocene ground quirrels. The latest possible date is the Atlantic, and its extinction was probably related to the local collapse of mammoth steppe. [18] Spermophilus superciliosus
The Holocene extinction was preceded by the extinction of most large (megafaunal) animals during the Late Pleistocene, a decline attributed in part to human hunting. [24] [25] The prevailing theory is that human overhunting, coinciding with existing stress conditions, likely contributed to this decline.
The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today); a proposed third epoch, the Anthropocene, was rejected in 2024 by IUGS, the governing body of the ICS.
Fossil evidence and rock art suggests that the species was more broadly spread around southern Africa in the Pleistocene and early Holocene, but its range contracted because of climate-driven vegetation change until it was reduced to just 4300 km 2 east of Cape Town. It finally disappeared around 1800 CE as a result of hunting, competition with ...
