In 1960, Huseynov carried out excavations in the valleys of the Quruchay and Kondalanchay Rivers, and in Nagorno-Karabakh Autonomous Oblast of the Azerbaijan SSR.
The cultural materials discovered in the caves of Azokh and Taglar (Karabagh), Damjili and Dashsalahli (on the Aveydagh mountain, the region of Kazakh, Zara, Kalbajar), Gazma (Nakhichevan) and Buzeir (Lerik) provide rich and varied evidence about the ancient peoples who settled in the territories of Azerbaijan during the Palaeolithic Age.
The scientific investigations that were carried out with modern methods and technical equipment of the last quarter of the 20th century proved that this jaw belonged to an 18–22-year-old woman, who lived 350–400 thousand years ago, during the Middle Ashel Age of the Lower Palaeolithic Period.
