The stone lion (Bardshir) is one of the cultural symbols of the Bakhtiari tribe, and as a sign of courage, they are placed on the graves of young people, athletes, and great and famous people. 
These statues were built in the Zagros mountains and outside this domain in a vast area called Bakhtiari, which today includes several provinces, over several centuries. These statues, which have been made from the past to the present, with different forms and modes, are decorated with motifs that originate from the cultural, social, and religious history of the people of these regions. 
With the aim of knowing the periods of the stone lion, this article attempts to investigate the similarities and differences between the stone lions in Ardal and Bazoft regions in terms of the form and carved motifs and examine the concepts which these forms and motifs represent. 
The present research used the descriptive-analytical method and employed the comparative approach Library and field studies were conducted to evaluate and compare the stone lions of these regions. The results of the investigations show that the forms and motifs of stone lions are different in every family and clan.
