The Holocene (/ ˈhɒl.əsiːn, - oʊ -, ˈhoʊ.lə -, - loʊ -/) [ 2 ][ 3 ] is the current geological epoch, beginning approximately 11,700 years ago. [ 4 ] It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. [ 4 ] The Holocene and the preceding Pleistocene [ 5 ] together form the Quaternary period.
The Holocene extinction, or Anthropocene extinction, [3] [4] is the ongoing extinction event caused by humans during the Holocene epoch. These extinctions span numerous families of plants [ 5 ] [ 6 ] [ 7 ] and animals, including mammals , birds, reptiles, amphibians , fish, and invertebrates , and affecting not just terrestrial species but also ...
199.6. Triassic–Jurassic extinction event, causes as yet unclear. 66. Perhaps 30,000 years of volcanic activity form the Deccan Traps in India, or a large meteor impact. 66. Cretaceous–Paleogene boundary and Cretaceous–Paleogene extinction event, extinction of dinosaurs. 55.8. Paleocene–Eocene Thermal Maximum. 53.7.
1926 [ 415 ] Extermination campaign. The Great Plains wolf has been later determined to be continuous morphologically [ 410 ] and genetically [ 416 ] with the still existing Mexican wolf, which would use the name C. l. nubilus if placed in the same subspecies, due to being the older one. Red-moustached fruit dove.
A chronology of climatic events of importance for the Last Glacial Period, about the last 120,000 years The Last Glacial Period caused a much lower global sea level.. The Last Glacial Period (LGP), also known as the Last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, c. 115,000 – c. 11,700 years ago, and thus corresponds to most of the ...
The Holocene Climate Optimum (HCO) was a warm period in the first half of the Holocene epoch, that occurred in the interval roughly 9,500 to 5,500 years BP, [ 1 ] with a thermal maximum around 8000 years BP. It has also been known by many other names, such as Altithermal, Climatic Optimum, Holocene Megathermal, Holocene Optimum, Holocene ...
The Holocene calendar, also known as the Holocene Era or Human Era (HE), is a year numbering system that adds exactly 10,000 years to the currently dominant (AD/BC or CE/BCE) numbering scheme, placing its first year near the beginning of the Holocene geological epoch and the Neolithic Revolution, when humans shifted from a hunter-gatherer lifestyle to agriculture and fixed settlements.
The Holocene glacial retreat is a geographical phenomenon that involved the global retreat of glaciers (deglaciation) that previously had advanced during the Last Glacial Maximum. Ice sheet retreat initiated ca. 19,000 years ago and accelerated after ca. 15,000 years ago. The Holocene, starting with abrupt warming 11,700 years ago, resulted in ...
