Lithic production, site formation and Middle Palaeolithic palimpsest analysis: in search of human occupation episodes at Abric del Pastor Stratigraphic Unit IV (Alicante, Spain)

摘要

We present the results of an exercise in Middle Palaeolithic palimpsest analysis geared toward the identification of human occupation episodes. It is based on a combined reading of the archaeosedimentary deposit and the archaeological record of Stratigraphic Unit IV from Abric del Pastor (Alcoy, Alicante, Spain), chronologically framed within MIS 4-5. A study of site formation processes coupled with archaeostratigraphic analysis of the lithic record incorporating Raw Material Units (RMU) and refits, as well as with combustion features and faunal remains enabled identification a minimum of 4 and a maximum of 6 human occupation episodes within lithostratigraphic units IVa, IVb and IVc. Through our data it reaches a high resolution temporal frame close to the ethnographic time scale, which constitutes a significant contribution for the knowledge of human occupations types and landscape use in the Mediterranean rim of the Iberian Peninsula during Middle Palaeolithic.
