Radiocarbon Dates on Some Quaternary Mammals and Artifacts from Northern North
Bibliographic record
Abstract
ABSTRACT. Nine radiocarbon dates on five genera of Quaternary mammals from north-em North America are discussed. Of particular interest are: (a) a 29,000-year-old artifact from the Yukon Territory: (b) the first evidence that steppe mammoths (Mammuthus. columbi or M. armeniucus) occupied eastern Beringia during the peak of the Wisconsin glaciation; (c) dates indicating that saiga antelopes (Saiga ratarica) and Yukon short-faced bears (Arcrodus simus yukonensis) occupied the Yukon-Alaska region in mid-Wisconsin time: (d) dates indicating that bison (Bison sp.) lived near the arctic coast of the Northwest Territories, and tundra muskoxen (Ovibos moschatus) lived in the western Yukon in late postglacial time; and (e) dates suggesting that tundra muskoxen have occupied the central Canadian Arctic Islands for the last 7000 years. RÉSUMÉ. Neuf datations au radiocarbone sont ici discutees; elles ont et6 obtenues pour cinq genres de mammifbres du Quaternaire des regions septentrionales de I’Ambrique du Nord. Les points particulibrement interessants sont: (a) un artefact date A 29,000 ans provenant du Yukon; (b) la premitxe preuve de la presence du mammouth des steppes (Mammurhus columbi ou M. urmeniucus) en Beringie orientale au maximum glaciaire du Wisconsin; (c) des dates indiquant que l’antilope saiga (Suigu rarurica) et l’ours à museau court du Yukon (Arcrodus simus yukonensis) occup&rent le Yukon et l’Alaska à I’epoque wisconsinienne moyenne; (d) que le bison (Bison sp.) vkcut prbs de la côte arctique des Temtoires du Nord-ouest, et que le boeuf musque de la toundra (Ovibus moschrus) habita l’ouest du Yukon & la fin de I’epoque postglaciare; (e) enfin, des dates suggkrant la presence du boeuf musque de la toundra dans les îles de l’Arctique Central canadien pour les derniers 7000 ans.

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.
