User:FerdinandLovesLegos/18th millennium BC

The 18th millennium BC spanned the years 18,000 BC to 17,001 BC (c. 20 ka to c. 19 ka). This millennium is during the Upper Paleolithic period. It is impossible to precisely date events that happened during this millennium, and all dates associated with this millennium are estimates mostly based on geological analysis, anthropological analysis, and radiometric dating.

Human culture
The formation of the swastika sign occurs in the Sagittarius era during this millennium. Within the Solutrean tradition, ranging from the 23rd to the 17th millennium BC, pressure flaking is used mainly in the production of small projectile points, but also in the final retouch of larger laurel-leaf points. Around this time, the Bull Cult painted in the Lascaux caves. As the European roots of the Bull Cult in the 18th millennium BC Caves at Lascaux with the painted aurochs and bison demonstrate, even earlier hunter-gatherer human communities revered several breeds of cattle, notably the Bull. With the state of research today, it is extremely difficult to recreate the Proto-Ainu language, which was spoken about in the 18th millennium BC.
