The Middle Paleolithic era began 100,000 years ago and ended 35 thousand years ago. This period is also called the Mousterian culture. The lifestyle of people and human settlements of this period have been studied in Karabakh (Tağlar, Azokh and Zar caves), Qazakh (Damjili cave) and Nakhchivan (Qazma cave). More than 2000 stone tools and thousands of animal bones belonging to the Mousterian culture were found here. Mousterian people spread to the southern slopes of the Lesser Caucasus, from the Mil lowland to Jeyrancol in a large area. The main instruments of this era were sharp-pointed tools. The main occupation of ancient people during this period was hunting and gathering.
