The Paleolithic Age, Era or Period is a prehistoric period of Aierian history distinguished by the development of the most primitive stone tools discovered, and covers roughly 95% of aierian technological prehistory. It extends from the earliest known use of stone tools in Aiers around 203.500 years ago (200.000 b.a.H), to around the 29.000 b.a.H.
The Paleolithic era is followed by the Mesolithic (29.000-19.000 b.a.H) and the later Neolithic (19.000 - 13.500 b.a.H) The date of the Paleolithic—Mesolithic boundary may vary by locality as much as several thousand years. During the Paleolithic period, aierian peoples grouped together in small societies such as bands, and subsisted by gathering plants and fishing, hunting or scavenging wild animals. The Paleolithic is characterized by the use of knapped stone tools, although at the time aierian peoples also used wood and bone tools. Other organic commodities were adapted for use as tools, including leather and vegetable fibers; however, due to their nature, these have not been preserved to any great degree. Surviving artifacts of the Paleolithic era are known as paleoliths. Some of the Aierian peoples gradually evolved from earlier members of their species and races – who used simple stone tools – into fully behaviorally and anatomically modern aierian peoples during the Paleolithic era. During the end of the Paleolithic, specifically the Middle and or Upper Paleolithic, aierian peoples began to produce the earliest works of art and engage in religious and spiritual behavior such as burial and ritual.
