The Mesolithic period began roughly 15,000 years ago and ended between 5,000 and 15,000 years before present depending on the region. This timeline varies across Eurasia as the era marked the final chapter of hunter-gatherer life before the dawn of agriculture.
British archaeologist Hodder Westropp coined the term Mesolithic in 1866 to describe this transitional phase. The term meaning middle stone initially faced controversy before gaining recognition as a crucial bridge between the deep past and the agricultural future by the mid-20th century.
The defining technological innovation of the Mesolithic period was the microlith which is a small geometrically shaped stone tool. These tiny blades were hafted into wooden or bone handles to create composite tools like arrows and spears that revolutionized hunting and gathering efficiency.
The earliest known pottery in the world was found in Xianrendong cave in China and dates back 20,000 years. This pottery was used by mobile foragers during the Late Glacial Maximum and overturns the assumption that pottery only emerged with the Neolithic Revolution.
The Maglemosian culture of Denmark and the Azilian culture of France exemplify the technological shift to microliths. These cultures yielded thousands of miniature tools while regions like Ireland and the Tyrrhenian Islands persisted with macrolithic technology using larger unmodified stone tools.
