|Subdivisions of the Quaternary System|
|Subdivision of the Quaternary period
according to the ICS, as of 2017.
In Europe and North America, the Holocene is subdivided into Preboreal, Boreal, Atlantic, Subboreal, and Subatlantic stages of the Blytt-Sernander time scale. There are many regional subdivisions for the Upper or Late Pleistocene; usually these represent locally recognized cold (glacial) and warm (interglacial) periods. The last glacial period ends with the cold Younger Dryas substage.

The Hamburg culture or Hamburgian (13,500-11,100 BC) was a Late Upper Paleolithic culture of reindeer hunters in northwestern Europe during the last part of the Weichsel Glaciation beginning during the Bölling Interstatial. Sites are found close to the ice caps of the time.
The Hamburg Culture has been identified at many places, for example, the settlement at Meiendorf and Ahrensburg north of Hamburg, Germany. It is characterized by shouldered points and zinken tools, which were used as chisels when working with antler. In later periods tanged Havelte-type points appear, sometimes described as most of all a northwestern phenomenon. Notwithstanding the spread over a large geographical area in which a homogeneous development is not to be expected, the definition of the Hamburgian as a technological complex of its own has not recently been questioned.
In the early 1980s, the first find from the culture in Scandinavia was excavated at Jels in Sønderjylland. Recently,[when?] new finds have been discovered at, for example, Finja in northern Skåne. The latest findings (2005) have shown that these people travelled far north along the Norwegian coast dryshod during the summer, since the sea level was 50 metres (160 ft) lower than today.
The distribution of the finds in the settlements show that the settlements were small and only inhabited by a small group of people. At a few settlements, archaeologists have discovered circles of stones, interpreted as weights for a teepee covering.
