Megalithic Cemeteries and Land Use in the Yān Oya River Basin of Sri Lanka
Bibliographic record
Abstract
Megalithism is a cultural phenomenon associated with mortuary rituals. Societies that practise megalithism construct burials and memorials using stone slabs in memory of the dead as a form of ancestor worship. Archaeological evidence shows that the remains of these cultural practices that originated during the Neolithic period, occur in various geographical zones around the globe. Across peninsular southern India and Sri Lanka megalithism is observed, reflecting the cultural identity of Early Protohistoric-Iron Age communities of South Asia and practised even today, in certain parts of India. In Sri Lanka, the Yān Oya macro region of the North Central Dry plains is a geographical region where megalithism is prevalent and visible on the landscape. Megalithic groups appear to have widely dispersed across the Yān Oya river basin from the early quarter of the 1st millennium BCE to the early quarter of the 1st millennium CE with their adaptive strategy contributing to the formation of the cultural landscape of the region. In this paper, the megalithic cultural complex in the Yān Oya macroregion is discussed using evidence from archaeological surveys and excavations, with a focus on territorial expansion, resource exploitation and land use pattern. Archaeological evidence points to a series of three patterns or phases where the megalithic community in the region developed from a nomadic or semi nomadic pastoral subsistence to a sedentary village based agro-pastoral subsistence.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
