A new platyspermic permineralised seed from the middle Jurassic of Queen Charlotte Islands, British Columbia, Canada.
Bibliographic record
Abstract
A description is given of the morphology, anatomy and affinities of a new permineralised seed from South Balch Island in the Queen Charlotte Islands, British Columbia, Canada. The seed is named iDawsonocarpus haidorum/i gen. et sp. nov. This platyspermic seed has features which show relationships with extant members of the Cycadales, coniferopsids and Gnetales together with Palaeozoic seeds e.g. platyspermic cordaites. These seeds are found in association with iCycadeocarpus columbianus/i Dawson in the Yakoun Formation, Vancouver Group, dated as Middle Jurassic (Bajocian), from associated ammonites. The seeds, in common with iCycadeocarpus columbianus/i, are calcified in a pyroclastic matrix and may be readily examined by conventional peel techniques and SEM.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
