Khok Phanom Di(Thai: โคกพนมดี ) is a large prehistoric settlement mound located 22 km from the shore of the Gulf of Thailand and about 40 feet high on the Bang Pakong River. Radiocarbon determinations place the occupation between about 2000-1500 BC. The location of Khok Phanom Di was highly strategic, providing sufficient supplies and access to fish and shellfish, potting clay, and coastal and river exchange routes.

Since 1978, Khok Phanom Di has been excavated on four different occasions, the most intensive taking place in 1984-5, when seven mortuary phases were identified in which the dead were interred over the ancestors in a period covering about 18 generations. This sequence enabled changes in the economy, material culture and social organization to be traced. Through these excavations, evidence of fishing, shell-harvesting, shell-jewelry production, and ceramic production has been found. Most importantly, during mortuary phase 3B, granite hoes, shell knives, and the remains of rice in human feces and stomach contents indicate that during this and phase 4, rice was being consumed.

Pre-Khok Phanom Di
Before Khok Phanom Di was an occupied site, the hunter-gatherer inhabitants of Thailand and Southeast Asia were considered to be Hoabinhian, a category of prehistoric human who lived approximately between 12000-10000 BC. The Hoabinhian has been defined by Chester Gorman as implementing simple tools such as unifacial stone flakes, sumatraliths, and a hunting-gathering lifestyle. During the early second millennium BC, however, Southeast Asia was infiltrated by rice farmers who originated ultimately in the Yangtze Valley of China. Khok Phanom Di was thus occupied as this influx of rice and millet farmers took place. Khok Phanom Di’s coastal location makes it a prime spot to settle down due to the access of both marine and terrestrial sources.

Nong Nor
The ancestral inhabitants of Khok Phanom Di were considered to originate from Nong Nor, a site located 27km from the Gulf of Thailand and 14km south of Khok Phanom Di. The site has been radiocarbon dated to be occupied as early as the 24th century BC. Artifacts uncovered from Nong Nor are shells, fishhooks, grindstones, stone adzes, and pottery vessels. All of these artifacts are found to be similar in form and decoration to the artifacts found at Khok Phanom Di, established a few centuries later. The similarities between artifacts demonstrate the possibility that Khok Phanom Di stems it's cultural traditions from Nong Nor. The settlement was only occupied for a few months, and the biological remains recovered reveal complete dependence on marine hunting and gathering, but environmental changes most likely pushed the inhabitants into agriculture and rice cultivation. However, there is no evidence of rice cultivation in Nong Nor, indicating that the transition occurred at Khok Phanom Di.



Khok Phanom Di
During the 1984-5 season of excavations, archaeologists uncovered a total of 154 graves in Khok Phanom Di that were separated out into seven different mortuary phases based off of stratigraphy and changes in cultural rituals. The first three mortuary phases, MP 1-3, indicated a marine-based hunter-gatherer society that relied heavily on shellfish, crustacea, and fish. Fish bones fashioned into bangles and cowrie shells were used as ornaments. Over half of the graves contain infants indicated high mortality rates due to anemic conditions and diseases such as malaria and thalassemia. MP 3B brought about a series of changes. The surrounding sea level fell and the freshwater resources increased. There was a significant increase in the number of freshwater fish bones and crab shells found in middens in MP 3B-4. A reduction in infant burials indicates better health among individuals and lower mortality rates. Agriculture may have found its way to Khok Phanom Di during MP 3B-4 due to domesticated rice husks found in fecal remains inside the pelvic area of skeletons in situ, which is backed up by less tooth wear in individuals because of the beneficial effects of rice. Strontium isotopes in the teeth of individuals showed that during MP 3B, females born and raised in a different habitat came to Khok Phanom Di, but MP 4 showed a decrease in strontium variance indicating a possible switch to a matrilocal society.

During MP 5-7, the area’s salinity increased with rising sea levels causing a reversion to marine hunting and gathering. More complex social constructs began appearing in Khok Phanom Di with a few rich graves suggesting high status. Burial 15, named “The Princess”, is a well-known burial in this site who was endowed with over 120,000 beads, exotic goods gained through trade, bangles, and an anvil. An infant with a similarly rich burial was buried nearby indicating the concept of status in the society. An increase in trade within these mortuary phases coincides with failing health which could have led to the abandonment of Khok Phanom Di.

Life in Khok Phanom Di
The well-preserved human skeletons gives us a chance to know the lives of the inhabitants of Khok Phanom Di. The analysis of the eruption pattern in teeth and the bone structure shows high infant mortality continually took place over MP1-3a, and the percentage of population dying at or soon after birth reaches as high as 41%, which may be due to the prevalence of the gene for thalassemia. This gene, while providing immunity to malaria, has the side affect of inducing anemia. However, there is a decline beginning from the fourth mortuary in that four fatalities aged under a year were reported in this phase. According to the isotope analysis, it is suggested that this change might be the result of immigration of a group of women from another area who did not carry the thalassemia gene.



Post-Khok Phanom Di
Surviving became increasingly difficult over time. Malaria caused death in infancy until they genetically adapted to it. Through environmental changes and the lowering of sea levels, the area became less swampy, hosting fewer mosquitoes. This change in environment and adaption increased infant survival. However, this genetic adaptation caused anemia, and although these individuals would survive infancy, many would not survive childhood. Those who survived childhood led lives of deformities such as thinned and shortened bones.

The abandonment of Khok Phanom took place between 1500-1400 BC. Although the inhabitants faced many difficulties with diseases and defects, such as dealing with malaria and anemia, the most probable cause in its abandonment was due to the declining advantages of location. Initially, Khok Phanom Di was a rich location located close to the sea, providing them abundant maritime wealth and resources, in which they centralized their livelihood around. The reduction of sea levels far from the vicinity of Khok Phanom Di made continuing their maritime hunter-gatherer lifestyle more difficult. This most likely forced these inhabitants inland, where they adapted into an agricultural lifestyle.

Archeological Significance
The archaeological significance that Khok Phanom Di provides is evidence to how humans transitioned from a simplistic hunting and gathering lifestyle, into agriculture in mainland Southeast Asia. Archaeologists also are able to see how burial methods changed over time, as seen in the items that were buried with the deceased would differ as the inhabitants lifestyle and culture changed. Khok Phanom Di introduces the idea that this transition led to a more complex society, and the change in diet over time would make them susceptible to sickness, as seen in the anemic skeletons.
