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.

On February 5, 1984, Ernesto Tabío Palma died in Cuba at seventy-two years old, ending six decades of continuous scientific productivity. Tabío left no autobiography, much less an assessment of the significant events in his life in Perú from 1953 to 1960. However, his career deserves an honorable place in the history of the Peruvian archaeology. He played a major role in Perú, compiling archaeological collections from sites along the entire Peruvian coast. His contributions to the field included investigations in Playa Grande, Ancón, Puruchuco sites, as well as a long list of publications in Cuba. Tabío Palma also produced one of the great doctoral theses of Peruvian archaeology developed via Marxist theory (1969b) in which he applied this methodology to archaeological material from the Casma, Huarmey, and Fortaleza valleys on the Central Coast of Perú.

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.

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...

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.
