The newly-discovered petroglyphs (at Tang-e Birzal) have located at a mountainous area, in 26 kilometers away from the northeastern point of Kohgiluye va Buier Ahmad Province, in pursuant of a nomadic trek road, and near Mondan village at Sarfaryab district of Charam town. These reliefs were found by a field consideration in 2013, but they have not introduced yet. These reliefs and drawings in this site (Tang-e Birzal) are divided into two categories: Geometric and Animal. The geometric reliefs and drawings have smallest number. These samples are like symbolic and meaningless signs and a personal name that has been possibly craved in the recent years. The animal reliefs and drawings like mountain goat have been created in the different sizes. These reliefs have been shallowly craved on the two lime rocks with the 5 meters away from each other. But some of these drawings have deeply carved at the first complex. These samples bring some questions to mind about their creators and their era and what kind goal has been behind them? A comparison between the petroglyphs' chronicle accrued to the Tang-e Birzal and other samples in the various points of Iran shows that some of these petroglyphs are related to the 2 nd Iron Era (based on their carving type and morphology) and that some other samples are associated to the history period. This paper is aimed to consider the complex 1 and 2, their structural style, artistic motifs, pictures and their related era.
