The 10th millennium BC spanned the years 10,000 BC to 9001 BC (c. 12 ka to c. 11 ka). It marks the beginning of the transition from the Palaeolithic to the Neolithic via the interim Mesolithic (Northern Europe and Western Europe) and Epipaleolithic (Levant and Near East) periods, which together form the first part of the Holocene epoch that is generally believed to have begun c. 9700 BC (c. 11.7 ka) and is the current geological epoch. It is impossible to precisely date events that happened around the time of this millennium, and all dates mentioned here are estimates mostly based on geological analysis, anthropological analysis, and radiometric dating.
The main characteristic of the Holocene has been the worldwide abundance of Homo sapiens sapiens (humankind). The epoch began in the wake of the Würm glaciation, generally known as the Last Ice Age, which began 109 ka and ended 14 ka when Homo sapiens sapiens was in the Palaeolithic (Old Stone) Age. Following the Late Glacial Interstadial from 14 ka to 12.9 ka, during which global temperatures rose significantly, the Younger Dryas began. This was a temporary reversal of climatic warming to glacial conditions in the Northern Hemisphere and coincided with the end of the Upper Palaeolithic. The Younger Dryas ceased c. 9700 BC, marking the cutover from Pleistocene to Holocene.
In the geologic time scale, there are three (tentatively four) stratigraphic stages of the Holocene beginning c. 9700 BC with the "Greenlandian" (to c. 6236 BC). The starting point for the Greenlandian is the Global Boundary Stratotype Section and Point (GSSP) sample from the North Greenland Ice Core Project, which has been correlated with the Younger Dryas. The Greenlandian was succeeded by the "Northgrippian" (to c. 2250 BC) and the "Meghalayan". All three stages were officially ratified by the International Commission on Stratigraphy in July 2018. It has been proposed that the Meghalayan should be terminated c. 1950 and succeeded by a new stage provisionally called "Anthropocene".

The Upper Paleolithic (or Upper Palaeolithic) is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 12,000 years ago (the beginning of the Holocene), according to some theories coinciding with the appearance of behavioral modernity in early modern humans, until the advent of the Neolithic Revolution and agriculture. Anatomically modern humans (i.e. Homo sapiens) are believed to have emerged in Africa around 300,000 years ago.
The latter half of the Late Pleistocene to the beginning of the Holocene (~50,000-10,000 years Before Present) saw extinctions of numerous predominantly megafaunal species, which resulted in a collapse in faunal density and diversity across the globe. The extinctions during the Late Pleistocene are differentiated from previous extinctions by the widespread absence of ecological succession to replace these extinct megafaunal species, and the regime shift of previously established faunal relationships and habitats as a consequence.
The Anthropocene (ˈænθrəpəˌsiːn,_ænˈθrɒpə- ) is a proposed geological epoch dating from the commencement of significant human impact on Earth's geology and ecosystems, including, but not limited to, anthropogenic climate change. neither the International Commission on Stratigraphy (ICS) nor the International Union of Geological Sciences (IUGS) has officially approved the term as a recognised subdivision of geologic time, although the Anthropocene Working Group (AWG) of the Subcommission on Quaternary Stratigraphy (SQS) of the ICS voted in April 2016 to proceed towards a formal golden spike (GSSP) proposal to define the Anthropocene epoch in the geologic time scale (GTS) and presented the recommendation to the International Geological Congress in August 2016.
Since its discovery in Greenland ice cores, the millennial scale climatic variability of the last glacial period has been increasingly documented at all latitudes with studies focusing mainly on Marine Isotopic Stage 3 (MIS 3; 28-60 thousand of years befor ...
A 1.70 m core extracted from the Lac des Lauzons, Haut Champsaur, French Alps, at 2180 m altitude, provided a detailed Holocene record of beetles, pollen and plant macrofossils, enabling the reconstruction of local palaeoenvironmental changes during the la ...
