Claim ledger
Stevens et al. publish a 24-species belemnite sample, first and last occurrence inputs, a 253.1 Ma youngest permitted origin offset and terminal K–Pg context, supporting a 253.1–66.0 Ma study-defined envelope rather than exact global FAD, LAD or continuous occupancy.
claim:taxon:belemnitida:source-bounded-range-rc50Known limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
