Abstract
Anserini indeterminate Material. Left carpometacarpus, proximal part, AaO-2663; left phalanx 1 of major digit of wing, AaO-735 (it is not possible to know whether they come from the same individual). The carpometacarpus shows the morphological characteristics of the Anserini (Woolfenden, 1961) and its size corresponds to the Recent species Branta canadensis, the Canada Goose. Its measurements are (in mm): proximal width, 9.1; proximal depth, 20.8. It is larger than the extinct species Branta woolfendeni, from the upper Miocene or lower Pliocene of Big Sandy Fm. (Bickart, 1990). On the phalanx the distal portion of the Pila cranialis phalangis is incomplete, mainly on the ventral side. This phalanx differs from that of the Anatinae by its much deeper Fossa ventralis. This Fossa ventralis is more developed in the proximal part of the phalanx. The measurements are (in mm): length (without the distal point), 32.4; proximal width (dorsoventrally), 8.0; proximal depth (craniocaudally), 7.3; maximum depth (craniocaudally) 10.4. As for the carpometacarpus, this phalanx is similar to that of the genus Branta but it is larger than the Recent Branta bernicla. Anserini (genus and species indeterminate) are present in the Pliocene of the Yorktown Formation. They are also comparable in size to Branta canadensis (Olson & Rasmussen, 2001).
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.
