The type of culture associated with the Mesolithic varies between areas, but it is associated with a decline in the group hunting of large animals in favour of a broader
hunter-gatherer way of life, and the development of more sophisticated and typically smaller lithic tools and weapons than the heavy-chipped equivalents typical of the Paleolithic. Depending on the region, some use of

Terminology
The terms "Paleolithic" and "Neolithic" were introduced by
John Lubbock in his work ''Pre-historic Times'' in 1865. The additional "Mesolithic" category was added as an intermediate category by Hodder Westropp in 1866. Westropp's suggestion was immediately controversial. A British school led by
John Evans denied any need for an intermediate: the ages blended together like the colors of a rainbow, he said. A European school led by

's work, ''The Dawn of Europe'' (1947), which affirms the Mesolithic, sufficient data had been collected to determine that a transitional period between the Paleolithic and the Neolithic was indeed a useful concept. However, the terms "Mesolithic" and "Epipalaeolitic" remain in competition, with varying conventions of usage. In the archaeology of Northern Europe, for example for archaeological sites in Great Britain, Germany, Scandinavia, Ukraine, and Russia, the term "Mesolithic" is almost always used. In the archaeology of other areas, the term "Epipaleolithic" may be preferred by most authors, or there may be divergences between authors over which term to use or what meaning to assign to each. In the New World, neither term is used (except provisionally in the Arctic).
"Epipaleolithic" is sometimes also used alongside "Mesolithic" for the final end of the Upper Paleolithic immediately followed by the Mesolithic. As "Mesolithic" suggests an intermediate period, followed by the Neolithic, some authors prefer the term "Epipaleolithic" for
hunter-gatherer cultures who are not succeeded by agricultural traditions, reserving "Mesolithic" for cultures who are clearly succeeded by the Neolithic Revolution, such as the
Natufian culture. Other authors use "Mesolithic" as a generic term for hunter-gatherer cultures after the Last Glacial Maximum, whether they are transitional towards agriculture or not. In addition, terminology appears to differ between archaeological sub-disciplines, with "Mesolithic" being widely used in European archaeology, while "Epipalaeolithic" is more common in Near Eastern archaeology.

last glacial period ended have a much more apparent Mesolithic era, lasting millennia.

Such conditions produced distinctive human behaviors that are preserved in the material record, such as the

timber longhouses and pottery) spread into Europe, the Mesolithic way of life was marginalized and eventually disappeared. Mesolithic adaptations such as sedentism, population size and use of plant foods are cited as evidence of the transition to agriculture. Other Mesolithic communities rejected the Neolithic package likely as a result of ideological reluctance, different worldviews and an active rejection of the sedentary-farming lifestyle.
In one sample from the
Blätterhöhle in
Hagen, it seems that the descendants of Mesolithic people maintained a foraging lifestyle for more than 2000 years after the arrival of farming societies in the area; such societies may be called "
Subneolithic". For hunter-gatherer communities, long-term close contact and integration in existing farming communities facilitated the adoption of a farming lifestyle. The integration of these hunter-gatherer in farming communities was made possible by their socially open character towards new members.

n sites, a "ceramic Mesolithic" can be distinguished between c. 9,000 to 5,850 BP. Russian archaeologists prefer to describe such pottery-making cultures as Neolithic, even though farming is absent. This pottery-making Mesolithic culture can be found peripheral to the sedentary Neolithic cultures. It created a distinctive type of pottery, with point or knob base and flared rims, manufactured by methods not used by the Neolithic farmers. Though each area of Mesolithic ceramic developed an individual style, common features suggest a single point of origin. The earliest manifestation of this type of pottery may be in the region around

Last Glacial Period.
The carbon 14 datation was established by carefully dating surrounding sediments.
Many of the pottery fragments had scorch marks, suggesting that the pottery was used for cooking. These early pottery containers were made well before the invention of agriculture (dated to 10,000 to 8,000 BC), by mobile foragers who hunted and gathered their food during the Late Glacial Maximum.
