Backward-bending walrus supply

Status: Prior

Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

Backward-bending walrus supply. As Greenland ivory prices fell against elephant ivory, Norse hunters intensified into riskier, more distant grounds — income-target behavior, not profit maximization. Falsify: the existing ivory isotope sequence against price series; profit-maximizers would have quit, not pushed north.

Kill-dataset (verbatim)

the existing ivory isotope sequence against price series; profit-maximizers would have quit, not pushed north.

Provenance

Run: Imported conversation (verbatim harvest) · model: claude-fable-5

Origin: operator conversation with Claude Fable 5 at max effort, conducted 2026-07-03, relayed verbatim by the operator into the shepherd session on 2026-07-04. No ModelRun exists for the original generation (it happened outside the pipeline); this transcript file is the canonical capture. Transcript path: docs/generated/conjecture_harvest_fablemax_20260703.md. Model (operator-attested, not pipeline-recorded): claude-fable-5. Novelty disclaimer (verbatim, load-bearing -- rule 4): "Same caveat as before, doubled: at 100 items across all of archaeology and history, some of these will have cousins in the literature I can't check. What I can guarantee is the format — each links two things not normally linked, and each names the dataset or measurement that would kill it."

Novelty / leakage triage

Leaked (already exists in the literature)

Substantially published: Barrett and colleagues document serial depletion with hunting shifting to smaller animals from progressively more distant northern grounds, and explicitly find that exploitation INTENSIFIED in the 13th-14th centuries as ivory values fell in Europe — the harvest item's core claim including the economic reading. Chosen deliberately as a triage calibration item.

Barrett et al. 2020, 'Ecological globalisation, serial depletion and the medieval trade of walrus rostra', Quaternary Science Reviews (Cambridge summary: 'Over-hunting walruses contributed to the collapse of Norse Greenland') — Intensification as values fell; northward shift
'Greenland Norse walrus exploitation deep into the Arctic', Science Advances (2024) — High-Arctic hunting grounds

Its literature citations feed the frontier as source leads (2 leads below the evidence/publication boundary, not yet reviewed).
