Abstract
The southeastern Caspian Sea, which archaeologists call the coastal zone, like many other areas of the Fertile Crescent, experienced significant changes in the structure of human societies on the cusp of the Neolithic Revolution in the early Holocene. Although archaeologists have been unable to establish a link between the end of the Mesolithic and the beginning of the Neolithic in the region, based on the current information, we now know that hunter-gatherers arrived in the area ca. 15,000 years ago. This marked one of the most important cultural events in human societies on the cusp of sedentism. One of the caves that has been studied as evidence of the presence of humans during the Mesolithic period is Kamarband (“Belt”) Cave. It is considered one of Iran’s most beautiful caves, attracting hunter-gatherer groups as settlers around 14,300 years ago. The cave was excavated by Carleton Coon between 1949 and 1951, and the description of his excavations during that time have fascinated readers for decades. Nevertheless, while Coon’s excavations at Kamarband Cave shed new light on the cultural epochs of the cave dwellers, they led to numerous ambiguities in understanding the chronological sequence of societies that existed in this cave for a variety of reasons. Over the past 70 years, archaeologists have not been able to accurately evaluate the cultural and social evolution of cave-dwelling human societies due to confusion in Coon’s excavation data. Therefore, a team of Iranian archaeologists re-excavated in limited and untouched parts of Kamarband Cave in 2021, managing to resolve some of the ambiguities in Coon’s chronology. Apart from the archaeological values of Kamarband Cave, recent excavations by the archaeological team have collected other valuable data, which will be addressed in other articles. This article primarily encompasses a chronological assessment of Kamarband Cave based on new data.

Introduction
Homo sapiens appeared on the planet about 300 thousand years ago, and except in the time range between 20,000 and 10,000 years ago, the range of remarkable changes among hunter-gatherer societies was not so noticeable and effective that it could cause fundamental changes in the dimensions (Watkins 2024, Flannery and Marcus 2012). The important point is that the cognitive capacities of Homo sapiens occurred around 40,000 to 50,000 years ago, called a revolution of behavioral modernity (Henshilwood and Marean 2003, Powel et al., 2009). However, archaeologists consider the evidence of this behavioral change in humans to be related to a period 15 thousand years ago. Caves such as the Kamarband, Hotu, Komishan and Ali Tepe, and the Mesolithic period significantly differ significantly from their predecessors. The results of archeological studies show that in the north of Iran around 14300 years ago, in the period from which terms such as Epipaleolithic or Mesolithic, a different and transformed society emerged. Scattered research shows the presence of humans throughout Mazandaran province from the Middle Paleolithic period onwards (Ramazanpour and Moradian, 2022). However, the basic question here is that in the southeast of the Caspian Sea, what were the characteristics of the transformative changes on the verge of the Neolithic? Apart from their chronological values, we need to know to what extent northern Iran sites excavated in recent years effectively understand the range of human developments in the Mesolithic and Neolithic periods. Investigating the Mesolithic and Neolithic periods can help us understand each society’s ideological and ritual concepts in the transition from the period of hunting and food gathering to the period of agriculture.
The Mesolithic period in the southeast of the Caspian Sea has been well-known for a long time due to the excavation of Hotu and Kamarband caves in 1949-1951 by Carleton Coon (Coon, 1951; 1957). Coon’s investigations and excavations in the plateau and north of Iran became a turning point in the recognition of an important period of human societies living in caves. Following that, a new wave of research began throughout this area. Despite the great fame of these two caves, unfortunately, there was no reliable information about this period, and the only reliable information about the Mesolithic period in the southeast of the Caspian Sea was related to the excavation of Ali Tepe Cave by McBurney and Komishan Cave by Vahdati Nasab. However, these communities’ social and economic status needs to be clarified (McBurney 1968, Vahdati Nasab 2021).
However, these excavations could not answer the questions of this period in the region; for this reason, in the winter of 2021, to review the stratification of the cultural deposits of the Kamarband and to investigate the resilience of humans with the environment from the Mesolithic to the Neolithic period; It was excavated for 40 days by a team from University of Tehran. Before the revision excavation, it seems the Neolithic context of Kamarband was destroyed, and our team only recorded layers of the Mesolithic period. This article describes the results of the 2021 excavation of the Mesolithic stratigraphy of Kamarband.

Kamarband Cave
Kamarband cave is located about 8 km west of Behshahr city and 7 km south of the Caspian Sea at a height of 36.40 meters above sea level. This Cave was first excavated in 1949 and 1951 by Coon. Coon started three trenches in this Cave, including Trench A, B and C. He identified 31 layers in Trench A (Fig. 4). Coon divides the Kamarband sequence into four cultural horizons based on the 28 layers from Trench A from top to bottom: Horizon 1: This period includes layers 1 and 2, consisting of mixed accumulation of Neolithic remains along with the Iron Age, the Islamic period, and the remnants of contemporary periods. Horizon 2: This period, considered the true Neolithic horizon, includes layers 3-10 and is divided into two parts, 2a and 2b. Section 2a includes layers 3 to 7, including pottery and bone remains of domesticated animals. Horizon 3: Upper Mesolithic period includes layers 11-17. Horizon 4: Early Mesolithic includes layers 21 to 28, the oldest phase identified in this Cave.
Kamarband Cave was re-excavated in 2021, and the team opened two trenches (D-E). In Trench D (2.20×3 M), the team recorded 28 contexts. After we removed all the rubbished materials from the Carleton Coon excavation of 1940, very small parts of the southern wall were untouched, which was very significant for stratigraphy. Context 1 contains the surface layer of the cave, and Context 2 contains the remains of the Coon`s excavation. Contexts 11, 12, 13, 14, 27, and 28 contain fireplace structures. Among the cultural remains in this trench, the team found remarkable plant remains such as seeds (recorded from fireplace structure), fossils, shells, snails, and stone artifacts. Trench E (65×220 M) after cleaning the Coon’s excavation, we reached the rocky bed of the cave, which allowed us to have a very good view of Trench E to control the section and stratigraphy. This trench is 65 x 220 cm. Context 1 is the surface layer, and contexts 2, 3, 5, 6, 7, 8, 9, 10,12,15,16,22,23,24,25,26,27,34, and 35 are fireplaces structures. Among these contexts, one of the special findings is the existence of many plant seeds. Contexts 13, 17, 18, 19, 28, 29, and 30 are settlement layers. Contexts 14 and 33 are rubble layers. Context 36 starts from -190 cm to -352 cm on the bedrock of the Kamarband cave and has no cultural finds. Context 37 is the bedrock. The cultural materials of this trench include stone artifacts, chipped stones, plant remains, animal remains, shells, snails, and fossils. Among the special 2021 excavations, we found the Carnivora /wolf teeth in many southeastern Caspian Sea caves, indicating a common shared ideology of Mesolithic people. Due to the destruction of the Neolithic layers in the cave, no evidence of pottery was found during the excavation. Only from Context 2, Trench D, which contained the remains of the Coon`s excavation, were pottery pieces obtained. 
Regarding the chronology of Kamarband Cave, Libby from the University of Chicago conducted the first C14 tests of Kamarband Cave on eight charred bone samples from the Mesolithic and Neolithic periods. Elizabeth Ralph studied the C14 results of the second season of the Belt Survey (Libby 1951, 1955). However, these results were problematic, so Gregg and Thornton have calibrated past radiocarbon results in recent years (Gregg and Thornton 2012).
Seven charcoal samples from the Trench E 2021 excavation were tested for absolute dating. The first sample of Context 2 (the uppermost layer) is related to the 11810 ± 60 BC period (Fig. 21). The second sample from context 10 shows the date 12030 ± 60 BC. The third sample is from context 16, showing 12010 ± 60 BC. The fourth sample is from context 13 and shows the date of 12150 ± 60 BC. The fifth sample from context 23 shows the date 12210 ± 60 BC, and a sample from context 29 shows the date 12200 ± 60. The last sample is the lowest space of fire preparation from a depth of 180 cm and shows a date of 12270 ± 60. The results of our studies indicate only the Mesolithic occupation of the Cave, while there is a short gap between the two trenches are visible, and it seems the Cave covered by pale soil/Loss. However, Coon’s report and his section indicate such a short cultural gap as well. It seems the Cave was abandoned much earlier before Younger Dryas and after a long interval before the Pottery Neolithic period was occupied again. During the Mesolithic period, the Kamarband Cave was highly used for daily activities, specifically for the production of stone tools. During the excavation of 2021, around 6736 stone tools were found in the two small trenches, while in the Hotu excavation 2020, less than 2000 stone tools from 10meter cultural layers were recorded, which indicates the different functions of the two Caves (Jayez et al., in press). 

Conclusion
According to the past and recent excavations of Hotu, Kamarband, and Komishani Tepe, we still see the chronological gap from the Mesolithic into the Early Neolithic period in the southeastern Caspian Sea shoreline. The emergence of the Modern Mind, the modern behavior revolution, and the formation of symbols and symbolic behavior are the main characteristics of the Mesolithic people of the Caspian Sea. The advances of warmer climate during the Bolling- Allerod period from 18,000 to 12,000 years ago caused the consumption of different resources and the subsistence strategy of the Caspian Sea cave people. From the 2021 excavation of Kamarband, we have recorded remarkable seed remains plus stone implements to support the theory of a new group evolving toward pre-agricultural management in one of Iran’s few regions of coastal societies.  

Abstract
A series of field activities including two seasons of survey and excavation at the Shahneh Poshte cemetery of Babol on the northern slopes of the Alborz Mountains in central Mazandaran in 2018 and 2019 resulted in the discovery of a collection of human graves and burials scattered throughout this 11-hectare site. Due to the mass of destruction caused by unauthorized excavations in the cemetery, several disturbed graves were observed without any classifiable information. In contrast, by conducting scientific excavations in the 16 trenches, a total of 39 identifiable and Readable human burials were found and then the collection of information and archaeological findings related to each burial was recorded and classified. In this study, we attempt to answer questions about the existence of possible burial methods and patterns and the meaningful characteristics of these variables by studying a set of different aspects including burial practices such as the position and orientation of the body, position of face of hands, architectural structure of the graves, gender and age of skeletons, individual and group burials, and burials with and without objects. The results of absolute dating and comparative studies indicate that this cemetery belongs to a long time span from the 11th and 12th centuries BC (Iron I) to the 4th and 3rd centuries BC, i.e. the Achaemenid to the early Parthian period (Iron IV), and therefore cultural materials of this cemetery are comparable to intra-regional ancient sites in Mazandaran as well as trans-regional sites in the Gorgan Plain, the Central Plateau, and especially the Gilan region. Our research also shows that the Shahneh Poshte graves follow a specific pattern in some burial aspects including the supine position and the direction of the face to the south and therefore have long-term burial traditions.

Introduction
The Shahneh Pashte cemetery is located adjacent to village of Kamikola and southwest of the Khoshrudpey city and 21 kilometers south of the Babol (Fig. 1) (Saedian, 2014: 321). This cemetery was excavated over two seasons in 2018 and 2019 by Hassan Fazeli Nashli. The result of these excavations was the identification of 39 human burials in situ (28 graves) (Fig. 2) which provide a set of valuable archaeological data such as absolute and relative dating, burial methods including the position and orientation of the bodies and faces, the position of the hands and the structure of graves. Based on the whole of archaeological data, the site can be dated to the late 2nd millennium B.C (late Iron I) to the mid-1st millennium B.C (Iron IV, 3rd - 4th centuries B.C / Achaemenid to early Parthian). More precisely, the absolute dating on 5 skeletons uphold this period. Based on archaeological studies between 39 burials, 29 burials belong to the late Iron I (late 2nd millennium BC) to Iron III (burials 1-11 and 22-39) are called “Iron age I - III Group” and the other 10 burials (burials 12-21) can be dated to the 4th and 3rd centuries B.C (late Achaemenid to early Parthian) that are called “Iron age IV Group”, considering the absolute dates of the two burials and their spatial relationship.

Discussion
The study of the Shahneh Poshte burials shows that a set of methods were used to place the deceased in grave which are divided into two general categories: lying on the sides and supine. These two general modes include a total of 11 sub-modes. In general, in the entire Iron Age in this site (I-IV), the lying on the sides includes 13 burials (33.3%) including 4 burials on the right and 9 burials on the left, supine 15 burials (38.5%) and also 11 burials (28.2%) lack any recognizable signs. In more detail, during the Iron I-III period, there were 8 contracted burials (28% of total) of which 4 were on the right and 4 on the left. In addition, 12 burials (41% of total) were buried in supine. Also, 9 burials (31% of total) were of unknown status. In the Iron IV, there were 5 contracted burials (50% of total) all of which were on the left and no right-sided burials were found. Moreover, 3 burials (30% of total) were buried in supine. Finally, 2 burials (20% of period) were classified as undetermined burials due to extensive damages (Fig. 3-5). Regarding the position of the hands of the skeletons, during the Iron I-IV, a total of 16 positions were observed which can be classified into three general groups: lying on the sides, supine and unknown. In addition, the first group includes 6 subgroups (25% of all), the second group is divided into 9 subgroups (54% of all) and the third group is divided into 9 cases (21% of all) as unknown (Fig. 6-7). In Shahneh Poshte, three types of grave architecture have been identified. The first is a simple pit, second is a simple pit with a clay cover and the third is a pithos. Of the 28 graves in site, 26 graves (93% of all) are simple oval pits, of which 20 graves belong to the Iron I-III (71.6%) and 6 graves (21.4%) belong to the Iron IV. The second method, a simple pit covered with big clay fragments includes only 1 is from Iron Age I-III (3.5% of total). Also the pithos burial consists of only 1 grave (3.5% of total) from Iron Age IV (Fig. 8-10). In terms of gender and age of the deceased in this cemetery, total of 9 burials (23% of all) were identified as male, including 8 burials (27.6%) in Iron I-III and 1 burial (10%) in Iron IV. In addition, there were 14 burials (36% of total) as female including 12 burials (27.6%) in Iron I-III and 2 burials (20%) in Iron IV. Also, of the total burials, 16 burials (41% of total) were disturbed (Fig. 11-17). In addition, 7 different positions of the bodies were identified in relation to geographical directions including: south-north 5% of all, east-west 2.5%, west-east 23%, northeast-southwest 10.5% of all, southwest-northeast 10.5%, southeast-northwest 10.5%, northwest-southeast 15% and also an unknown direction 23% of all burials (Fig. 18-19). It is worth noting that for the orientation of face, during all periods, the dominant method was the south direction with a total of 23% of all burials, and especially 20.5% of all in Iron I-III, it was certainly the most common burial method. It seems that this method was not a priority in the Iron IV and was used less often. After that, the north direction was the most common method with 15.3% including 10.2% in Iron IV and 5.1% in Iron I-III (Fig. 20-21). Regarding other study characteristics, 67.8% of the total graves are individual and 32.2% are group graves. Among the first group, 53.5% of the total is related to Iron I-III and 14.6% are related to Iron IV. In addition, group graves comprise 32.2% of the total graves of which 621.5% are related to Iron I-III and 310.5% are related to Iron IV (Fig. 22-25). Finally, about the possession of objects, in total, 70% of all burials were buried with burial objects and 30% did not contain any goods (Fig. 26-27). Finally, regarding the amount of possession of objects, in total, 27 burials (70% of all) were buried with burial objects, and only 12 burials (30% of total) did not contain any burial objects or grave goods.

Discussion 
Human skeletons in Shahneh Poshte cemetery are mostly buried in individual and group graves, including 28 graves which mostly include simple pits, one case of a simple pit with a clay cover and one pithos. In fact, the architectural of the graves was mostly in form of simple pits. A simple pit grave with a clay cover is quite unique in this site and a similar the grave has apparently been found only in one grave in the Lefork cemetery of Savadkuh which has been dated to Iron Age III (Abedini, 2017: 154). Third group of tombs is pithos type that has many similar older and contemporary examples in Mazandaran county. Among the numerous similar examples in the Iron Age of Mazandaran, can mention the children’s tombs in Gohar Tepe (Piller and Mahfroozi, 2009: 19) and cemetery Amirkola in Savadkuh (Abedini, 2017: 154), as well as Qaleh Kuti I cemetery (Fukai and Ikeda, 1971: Pl. XIX, Fig. 2) and Kaluraz in Gilan (Fahimi, 2002: 106-107), Tepe Gyan (Contenau and Girshman, 1935: 12), Maral Tepe of Uzbeki (Majidzadeh, 2008: 135-136) and Dinkhah Tepe (Muscaerella, 1974: 75). In addition, this method reached its peak of use during the Parthian period such as Taq bustan in Kermanshah (Kambakh Fard, 1998: 45), Liarsang-Ben cemetery in Gilan (Jahani et al., 2023: 38; Jahani et al., 2018: 114), and especially in the central Zagros basin (Mohammadi Far and Hojabari Nobari, 2004) such as Sanandaj (Khosravi et al., 2018: 317), Marivan (Mohammadi Far and Sarraf, 2006; Masoumian and Rahimi-Galugahi, 2012: 428) and several points in the city of Hamadan and its surrounding areas (Azarnoush, 1975: 56, vol. 7; Dailer et al., 2013). The graves of Shahneh Poshte are scattered in different parts of the cemetery and it does not seem that a specific space of the cemetery was dedicated to a specific group or class of people in this society. The group graves are in the form of two-burial and three-burial graves with a slight difference in depth and space compared to each other, although the attribution of some of these group burials to each other has been ambiguous. However, the spatial proximity of the skeletons and their burial objects and the difficulty in distinguishing them from each other led to the attribution of some of them to a single grave and it seems that even despite a slight difference in depth, there was a clear awareness in creating a single grave for multiple skeletons. Usually, the deceased were placed in the grave in various positions, either contracted (lying on their sides) or supine with different positions inclined to the right or left. The positions of the hands are usually in front of the chest and face and sometimes in line with the body and the legs are also bent in three different degrees: less than a 90-degree angle (high, inclined inward towards the abdomen and spine: grade 1), 90-degree angle (medium, perpendicular angle to the spine: grade 2), and more than 90-degree angle (low, open angle to the spine: grade 3). A few are also supine and extended in line with the body.

Conclusion
The study of the burials of the Shahneh Poshte cemetery shows that there were a group of methods and rituals related to the burial of the dead, some of which were used more than others and, in other words, became a burial tradition. Regarding the position of the dead during the Iron Age and during the use of this cemetery, all the conventional methods of placing the deceased in the grave were used in the Shahneh Poshte area and despite the slightly higher number of supine method, it does not have a significant advantage over the lying on sides method and both methods can be seen as burial methods and traditions in great abundance. Also, the supine method was the most common burial method among women with 71% and men did not have any dominant method. In the discussion of the architectural structure of the tomb, the common tradition and method, the usual method is a simple oval pit but there are two unique methods, one is a simple pit grave covered with pottery fragments and the other is a pithos burial, each of which was used in the form of a grave only as a specific method, not a burial tradition. Finally, based on the set of burial characteristics of the Shahneh Poshte cemetery, it can be seen that this site is comparable in many aspects to sites within the region in Mazandaran and adjacent the region especially Gilan and the Central Plateau. It can also be considered that the set of burial methods and traditions of the Shahneh Poshte cemetery is homogeneous and identical to other contemporary sites in Mazandaran and to some extent a continuation of some pre-Iron Age burial methods in this region.
