Abstract
La madera y huesos petrificados referidos por los jesuitas Ovalle, del Techo, Sepp, Lozano, Guevara, Sánchez Labrador, Dobrizhoffer, Falkner y Juárez en varios textos escritos durante los siglos XVII y XVIII constituyen uno de los primeros registros de plantas y animales fósiles en la Cuenca del Plata. La mayoría de los jesuitas consideraba a los ríos Paraná y Uruguay capaces de transformar la madera y también los huesos, en piedra, y por ende, a las petrificaciones comúnmente desenterradas de sus barrancas arenosas como formadas por el agua. Por otro lado, mientras Guevara relacionaba los grandes huesos comúnmente hallados en la desembocadura del río Carcarañá con una raza extinguida de gigantes, Falkner describía la coraza de un gliptodonte y Sánchez Labrador explicaba la presencia de invertebrados marinos en los alrededores de Buenos Aires invocando al Diluvio.

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.
