The excavation was conducted in a limestone cave deep in the ancient rock mountain range in the (presumed) Northwest region of the Southeast Asian peninsula, which has long been known for its archaeological deposits from the Late Stone Age to the Bronze Age. Sedimentary layers and stratigraphic features indicate that the area was inhabited at least 7,000 – 4,000 years ago, corresponding to the Late Neolithic and Early Metal Age periods.

Preliminary analyses of the sediments surrounding the remains indicate that the soil layer where the remains were buried is between 3,500 – 2,800 BC, or more than 5,000 years old. Although no official C14 dating results have been obtained, the burial characteristics and accompanying artifacts support the early prehistoric metal age date.

The artifacts were discovered in a sedimentary cave with three large chambers, the cave floor formed by the weathering of limestone over millions of years. The skeleton was located in the center of the second chamber — a well-preserved area, little affected by water flow or animal encroachment.

The excavation process showed that:

The skeleton was placed in an oval burial pit, unusually large in size.

The length of the skeleton was up to 2.2 – 2.4 meters, exceeding the average prehistoric human size in the area (1.55 – 1.65 m).

The fossilized plant patterns and fern leaves arranged around the skeleton suggest a ritual burial.

The preservation is so good that each bone segment and each joint structure detail can be clearly seen, suggesting that the airтιԍнт cave environment prevented organic decomposition.

The discovery of this large skeleton in a cave is one of the most unusual and valuable archaeological findings in the region in recent years. It not only raises questions about the idenтιтy and morphology of the prehistoric inhabitants, but also provides insights into the burial rituals, production tools and spiritual life of the ancient community.

When modern analytical methods — such as C14 dating, molecular biology and environmental archaeology — are applied, this skeleton could become the key to unlocking the unsolved chapters of Southeast Asia’s prehistory.
