Las investigaciones sobre la morfotecnología y tipología lítica en la sierra sur del Perú, no han sido aún elaboradas, contando tan solo con descripciones superficiales. El presente trabajo expone los resultados de la aplicación del registro morfotecnológico efectuados a la colección lítica de Arcata. Los análisis nos han permitido, identificar puntas bifaciales, preformas de puntas, raspadores y otros artefactos de piedra. Estos han sido asociados desde el punto de vista morfotecnológico con otros yacimientos arqueológicos.

Between 1966 and 1968, Richard MacNeish led the "Ayacucho Archaeological-Botanical Project" program in the Ayacucho basin, Huamanga province. There, they found more than 450 sites with human occupations. The Jaywamachay eaves stand out for their exhumed archaeological record. Excavations in 1969 and 1970 revealed the region's oldest human occupations. Detailed descriptions were published only for specimens corresponding to hunter-gatherers living during the last millennium of the Pleistocene and using Fell points. Due to the importance of these findings, the lithic remains (n = 4,388) contained in the twelve earliest strata of the site that present an age ranging between 11,603 and 9,556 calibrated years before the present were organized and studied. The analysis allowed us to identify two clear artifactual sets of different techno-morphological characteristics and chronologies. Due to t...

El 5 de febrero de 1984, falleció a sus 72 años Ernesto Tabío Palma; finalizando así seis décadas de continua productividad científica. Tabío no ha dejado una autobiografía y menos aún una evaluación de los importantes hechos de su vida en el Perú desde 1953 a 1960. Este científico merece un digno lugar en la historia de la arqueología peruana. Él realizó importantes aportes en el Perú, formando colecciones arqueológicas de toda la costa peruana. Su contribución académica incluye investigaciones en Playa Grande, Ancón y las ruinas de Puruchuco, y posee una larga lista de publicaciones en Cuba. Además, Tabío Palma, tiene una de las mejores tesis de investigación en la arqueología peruana desarrollada con la teoría marxista (1969b). Esta metodología fue aplicada a los materiales arqueológicos procedentes de los valles de Casma, Huarmey y Fortaleza, de la Costa Ce...

The analysis of archaeological lithic material from the Pikimachay cave at the Ayacucho Complex corresponding to the Final Pleistocene, have led to definite typological identifications such as core debris, first and secondary flakes, and fragments of slices which were most likely obtained through soft or hard hammer percussion. This study shows the results of an analysis of metric measurements applied to the collection conducted under the methodology of “Chaîne Opératoire” with the goal of identifying possible measures and the average order sequence for stone carving. However, knowing that we have minimal qualitative evidence on the archaeological lithic material from the Ayacucho Complex, the results of the preliminary analysis have demonstrated the association with three moments of stone carving.

A labor research of a lithic series from two archaeological sites located at the Chusqui District (Ayacucho) revealed the occurrence of true blades of basalt and quartz sandstone that were associated with sherds of both Early Intermediate Pe-riod and the Middle Horizon (ca. 0-900 AD). In this report we present the results of the examination of this series by stressing out some key and relevant data like the preparation of the blade cores from which blades were removed as well as the skills of the flintknappers applying this kind of rare recorded lithic technology yet not for that reason less important.
