Abstract
By author has been studied the areas of Jam, Riz, Saadat Shahr, Marvdasht, and Kazeron in Fars and Bushehr provinces from years of 2000 to 2007. During these surveys, 19 cave and rock shelter of Paleolithic period from plains of Jam and Riz are identified in southeast of Bushehr province that from this number, 5 sites related to Paleolithic period. The pastoral nomads of inhabitant in Bushehr province are most important groups of user these caves and rock shelters in plains of Jam and Riz. In this research are studied destruction factors of first of communities in south Zagros. The mining operations, non-standard construction, and excavations of illegal are the main factors of destruction in these sites. Furthermore, non-standard gathering the stone tools from Paleolithic period by archaeological students, and also unfamiliarity of the managers of cultural heritage of this region, are other the factors destruction these sites. So, for prevent the destruction of these sites must be done training local people and participation them in tourism this area. Introducing these tourist places in different ways is an important task to introduce these traces. Also, the build of museum site in the Paleolithic caves, and training of local children and tourists children, are from other effective actions. In this research for the first time, is study pathology of Paleolithic sites in Iran. The method of doing this research is descriptive-analytical. The analysis of this study is more reliant on information, founds, and data. So, in this research following questions are raised: Which is factors the main factors of destruction the sites of the Paleolithic period in South Zagros? And, what practical measures are there to protect these ancient sites? 
Keywords: Pathology of ancient caves, Paleolithic sites, South Zagros.

Introduction
Due to human activities are destroyed many of ancient traces as stone tools or faunal remains in the sites, caves, and rock shelters. The Mining operations, non-standard construction, and road construction are from main factors of destruction in ancient sites. The recent surveys are showed some of the caves and rock shelters of Paleolithic period in south Zagros affected by livelihood issues of pastoral nomads and indigenous people have been destroyed (Dashtizadeh, 2000, 2005, 2006a, 2006b, 2006c, and 2006d). The purpose of this research is survey destruction factors in these ancient sites.
In this research for the first time, is study pathology of Paleolithic sites in Iran. The method of doing this research is descriptive-analytical. The analysis of this study is more reliant on information, founds, and data. So, in this research following questions are raised: Which is factors the main factors of destruction the sites of the Paleolithic period in South Zagros? And, what practical measures are there to protect these ancient sites? 
For doing this research has been used from field surveys that by author gathered from areas of Jam, Riz, Saadat Shahr, Marvdasht, and Kazeron in Fars and Bushehr provinces from years of 2000 to 2007.

General description of studied areas and main factors of destruction of Paleolithic sites and protective solutions
By author has been studied the areas of Jam, Riz, Saadat Shahr, Marvdasht, and Kazeron in Fars and Bushehr provinces from years of 2000 to 2007. During these surveys, 19 cave and rock shelter of Paleolithic period from plains of Jam and Riz are identified in southeast of Bushehr province that from this number, 5 sites related to Paleolithic period (Dashtizadeh, 2009). The pastoral nomads of inhabitant in Bushehr province are most important groups of user these caves and rock shelters in plains of Jam and Riz. Furthermore, 17 caves and rock shelters of Paleolithic period have been identified from the plain of Saadat Shahr (Dashtizadeh, 2006c, 2006d, and 2012). Of course before that 17 caves and rock shelters of Paleolithic period have been identified from the Marvdasht plain in the northeast of Shiraz. From the Kazeron plain have been identified numbers of 27 caves and rock shelters of Paleolithic period. For this research is again studied the basin of Maharloo lake (Barfi, 2007). Generally, mining operations, non-standard construction, excavations of illegal, pastoral nomads, unfamiliarity of the managers of cultural heritage of this region, and non-standard gathering the stone tools from Paleolithic period by archaeological students are the main factors of destruction in Paleolithic sites in the area of south Zagros. First these archaeological sites are must be on the national monuments list. One of the main duties of the Cultural Heritage Organization is training the local community and tourists to preserve national monuments. Education and awareness of people this region (As the main guardians of the cultural heritage), is important work in this direction. The build of museum site in the Paleolithic caves, and training of local children and tourists children, are from other effective actions.

Conclusion 
Generally, mining operations, non-standard construction, excavations of illegal, pastoral nomads, unfamiliarity of the managers of cultural heritage of this region, and non-standard gathering the stone tools from Paleolithic period by archaeological students are the main factors of destruction in Paleolithic sites in the area of south Zagros. It seams, first these archaeological sites are must be on the national monuments list. One of the main duties of the Cultural Heritage Organization is training the local community and tourists to preserve national monuments. Education and awareness of people this region (As the main guardians of the cultural heritage), is important work in this direction. The build of museum site in the Paleolithic caves, and training of local children and tourists children, are from other effective actions.

Iran holds great significance for the question of the eastward expansion of the Acheulean hominins, as it is situated between the Arabian Peninsula and the Indian subcontinent, both of which have long and rich records of the Acheulean techno complex. Despite its strategic location, Iran has produced little evidence of the Acheulean techno complex. The only notable examples have been found in the western and northwestern regions of the country. The absence of Acheulean sites in southern Iran cannot be justified. Because this region, located in the northern parts of the Persian Gulf, was one of the main dispersal routes for Acheulean hominins towards the east. Here, we present a report on the discovery of a Lower Paleolithic locality near Dehtal, located in the northern region of the Persian Gulf. Additionally, we discuss the techno-typological characteristics of the lithics found in the area. Dehtal yielded a small, but characteristic lithic assemblage, which included a handaxe, a massive scraper, a large flake, and a flake core. The raw materials used are sandstone and fossiliferous limestone rock, which can be found as cobbles and boulders in secondary contexts on the northern slopes of Par-e Lavar. In addition to these findings, two boulder cores with large removal scars were also documented in the area, indicating large flake production in this locality. The site offers a unique opportunity to study a lithic assemblage in a relatively unknown area within the distribution range of the Acheulean technocomplex.
