Las Brusquillas 1 (partido de San Cayetano, provincia de Buenos Aires): un nuevo sitio del Holoceno tardío del área Interserrana de la región pampeana Las Brusquillas 1, San Cayetano county, Buenos Aires province: a new late Holocene site in the Interserrana area of the pampas region
Bibliographic record
Abstract
Durante el Holoceno tardío, en la región pampeana aumenta de modo significativo el número de sitios arqueológicos con respecto a momentos previos. No obstante, son escasos aquellos ubicados cronológicamente en los inicios de este periodo (entre 3500 y 2500 años AP). En este contexto, cobra especial relevancia para la arqueología regional el sitio en posición estratigráfica Las Brusquillas 1 (LB1), localizado en el área Interserrana bonaerense, con un fechado radiocarbónico de ca. 3300 años AP para las ocupaciones tempranas. En este trabajo se presentan los resultados del análisis tecnomorfológico de los artefactos líticos y del análisis taxonómico y anatómico de los restos faunísticos correspondientes a esas ocupaciones. Los objetivos son discutir las estrategias tecnológicas y de subsistencia y contribuir a la definición de la funcionalidad de LB1 en momentos tempranos del Holoceno tardío. Las evidencias senalan que los cazadores-recolectores emplearon mayoritariamente ortocuarcita para la manufactura de instrumentos unifaciales y que el principal recurso explotado fue el guanaco (Lama guanicoe), en coincidencia con los hallazgos producidos en otros sitios del área Interserrana con cronología similar. Por último, la información obtenida sugiere que LB1 representa un campamento residencial. The frequency of Late Holocene archaeological sites from the Pampas region is higher when compared with previous periods. However, the sites corresponding to the early Late Holocene are scarce. In this context, the site of Las Brusquillas 1, located in the Interserrana area and dated to ca. 3.300 years BP, becomes especially relevant for regional archaeology. The results from the technological and morphological analysis of the lithic material and the taxonomic and anatomical study of the faunal remains are presented in this paper. The objectives are to discuss the technology and subsistence of the hunter-gatherer groups that occupied the site and to contribute to the explanation of its function. The results from Las Brusquillas 1 show that quartzite was the preferred raw material for the manufacturing of unifacial tools, and that the main animal resource exploited was guanaco (Lama guanicoe), in concurrence with archaeological evidences from other sites of similar chronology located in the Interserrana area. In relation to functionality, the evidence indicates that LB1 represents a residential camp.

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.
