Variability of limestone knapping methods in Middle Palaeolithic levels M and Ob of Abric Romaní (Barcelona, Spain)

Abstract This paper presents the limestone reduction sequences documented in levels M and Ob at Abric Romaní from a technological point of view. At level M, recurrent knapping system has been identified, resulting frequency pseudo-Levallois blanks. archaeolevel Ob, presence Levallois methods are observed association with this system. In both cases, retouched tools rare dominated by notches denticulates. Although it is not well-known degree similarity difference between two relation to occupational patterns well understood, Neanderthals employed more opportunistic strategies, investing less time energy procurement raw materials including for chert. although still collected local fluvial deposits, differences material have identified Results show plasticity versality that had how they took advantage different abiotic resources around them. paper, we discuss technology context Iberian Peninsula.
