Excavations at Samrong Sen, which started in the 1880s, have been described as the earliest prehistoric archaeological studies which gave credence to the concept of Southeast Asian Bronze Age. Excavations conducted to depths of 6 metres (19.7 ft) stratifications have revealed that Samrong Sen provides a link to the professional skills and burial practices of the Bronze Age communities who lived in the Banchiang area on the banks of the Chinit River. As Samrong Sen was almost the only known prehistoric settlement in Cambodia for many years, it was visited by many archaeologists and its artefacts were studied by scientists in several countries. It has been characterized as a highly developed Stone Age

History

Though various spellings have been presented, “Samrong Sen” is considered to be correct. The site was first discovered and reported in 1876 by M. Rouques, Director of the Fluvial Transportation Company. Samrong Sen was subject to archaeological excavation from the late 19th century through the end of the 19th century, and also into the 20th century. The excavations show close relationship with Neolithic

. They have revealed that the people who lived at Samrong Sen during the Bronze Age were very similar to the ancestors of the Funanese. Archaeological history of the village in general and the research finding of the archaeological site in particular have been reported by archaeologists Corre in 1879, Fuchs in 1882 and 1883, Mansuy in 1902, Mourer in 1994, Vanna in 1999, and many Cambodian archaeologists and researchers.

Initial villager excavations
Initial finds at Samrong Sen were by villagers' excavations while extracting for hydrated lime from shell excavations at this site; these initial finds were handed over by the villagers to the missionaries. After the first excavations of 1876 in the flood plains of Tonle Sap, additional excavations were carried out by archaeologists at different locations within this site. Many of the large size collections made from the site during several excavations could have been from casual surface excavations and hence no specific methodology could be explained.

19th century
The earliest artefacts were found by Lieutenant Jean Moura in 1876; he was the Representative of the French protectorate of Cambodia in 1864. The stray archaeological finds were transported to France

 where they were analysed and interpreted. The Fuchs report of 1883 stated that the top layer consisted of recent flood deposit (inferred from recent pottery). Below this layer were shell lenses which contained black pytahanite, gouges, and chisels. There were also marine shell bracelets, as well as pottery vessels with varying type of incisions. Comparing it with the Mekong delta sediment deposits, Fuch inferred that the site existed a few centuries prior to the advent of Christian Epoch. These excavations also inferred that the site belonged to the Bronze Age on the basis of a comparison of the archaeological finds of similar sites in Thailand

 control started in 1902, and again in 1923 by Mansuy. Three layers were identified, which revealed shell lenses up to 4.5 metres (14.8 ft) depth. Arm bands and beads found here have similarity with those found in the Mekong sites. Pottery found here was not of any decorative type. Graves, however, gave many finds of fully formed bronze vessels. Excavations carried out in stratified layers have unearthed late Stone Age ceramics and also human remains, out of which many layers are dated 2000 BC, as per radiocarbon dating methods. However, the bronze collections were not found from excavations carried out in stratified layers. Several observations were made on the claims of archaeologists during the early stages of the excavations such as they were overzealous and that they over stated when presenting their findings.

Finds of Mansuy were further examined by French archaeologists in 1998 for human skeletons. This study identified three fully preserved skulls. In addition, 20 mandibles and several post-cranial ones found here established that these belonged to at least 20 people. Also found was a bronze mould and various arrowheads, axeheads, chisels and fish hooks etc.

Geography

Samrong Sen is located in central Cambodia on the east bank of the Stueng Chinit River, in the flood plains of the Tonle Sap River, near the ancient capital of Oudong

. The site is approachable from the Kampong Chhnang, which is 22 kilometres (13.7 mi) away. The village below which the prehistoric archaeological finds are found, is a rugged mound of elliptical shape with a length of 600 m laid in a north-south direction. In the first report made by Edmond Fuchs in 1883, the site was identified as covering an area of 300 metres (984.3 ft) by 150 metres (492.1 ft). It was about 5 metres (16.4 ft) to 6 metres (19.7 ft) above the Chinit River during low flow season. While parts of the site were exploited in the 1930s, the surviving portion as of the 1960s, is situated on the right bank of the Strung-Kinit, a rivulet within the waterway that flows from the Kompong-Leng mountains into the Tonle Sap. The site is approached along the waterway by inland transport from Kampong Chhnang port across the Tonle Sap Lake via the Steung Chinit River. The road approach is, however, seasonal only on a non-monsoon road.

The area gets exposed during the dry season from October to May when bush vegetation and water plants grow here and fishing is common vocation. The villagers subsist on hydrated lime extraction from the shells and fishing, activities that were recorded by the earliest researchers of the site and which had continued till the 1930s. As of 1999, 1237 people lived here in 235 stilt houses. A school and a Buddhist Pagoda were also reported in the village.

Fauna

Findings

Morphological characteristics of the tools have been the basis for the categorization of the Samrong Sen stone tools. The adzes, axes, shouldered adzes, shouldered axes, gouges, chisels, a burnisher, a tool used as a hammer are the eight identified categories. The most common tools found were adzes, followed by chisels and gouges. Axes and shouldered axes were very few. In the early excavation stages, flakes, debris, pre-forms and unfinished tools were not part of the collections. Further, though tool-manufacturing techniques could not be correctly discerned, it has been inferred after careful study of the tools that picking or flaking was the initial step followed by partial, edge, and full grinding. It has also been conjectured that sawing techniques were used.

The adzes have quadrangular sections similar to those found in Indo-China, Southern Thailand

. The stone gouges are linked to similar ones found in Marianas. Other antiquaries included ceramics, stone tools (adzes), a decorated bronze bell (19.7 cm in height), bone spear, harpoon shafts and human remains. Polished stone tools were used for wood working activities and pottery vessels and were produced by professionals.

 in Cambodia.” On the basis of studies carried out in ancient archaeological sites in Thailand the occupation of the area in the Neolithic period has also been inferred through the remains unearthed at the Samrong Sen site, as establishing occupation during Bronze Age (after 2000 BC). There is a certain degree of confusion in this dating since it has been noted that “Neolithic/Bronze Age periods are poorly separated” at the Cambodian sites.

Other observations showed that the ceramics contained decoration that are incised or impressed, a stylish technology which could exist at other locations; an earthenware vase mounted on a pedestal (reported by Mansuy in 1902 and in Mourer in 1971) attests to the polished stone adzes of the late Neolithic or early Bronze Age and are found in the adjoining countries of Thailand and Vietnam; stylistic changes have been recorded in the stratigraphic sequences such as in the curvilinear geometric ware. With findings of bronzes, arrow heads, hooks, bracelets, an axe, and a sandstone mould for axes, the excavations have also bridged the information gap between the Bronze Age with the excavations done at Angkor Borei

. The Bronze Age manufacturing of bronze finds at Samrong Sen and other sites in Cambodia are inferred to have been the outcome of supplies of ingots of copper received from central or northeastern Thailand, as Cambodia lacked any copper resources in its own territory. The finished bronze products produced in Cambodia are, however, testified by the large quantity of moulds and workshop remnants found during excavations.
It was also revealed that the settlers of Samrong Sen lived in bamboo houses on stilts, much like today

Some artefacts from surface collections are also kept with the Departure of Culture. The artefacts found by the Cambodian archaeologist L.
