At Boker-Tachtit (47-42 k.a. BP) a special form of the Levallois technique that shifts over time (Level 1-4) to an upper Paleolithic blade technology. The aim of the operational sequences in all levels was the production of blades that are shaped like elongated Levallois-points. Technologically, upper Paleolithic tools (Endscrapers and Burins) are common in all levels, while Levels 1 and 2 are also characterized by the occurrence of Emireh points (“Emirian”).

The antecedents for this technological evolution have not been identified up to now. Marks originally described the Boker-Tachtit sequence as a gradual technological transition in situ between Level 1 (terminal Mousterian) and fully Upper Paleolithic (Level 4), while other archaeologists suggest that this succession essentially represents four fully Upper Palaleolithic occupations.
Ensembles similar to Boker-Tachtit 1 were found in not only in the Levant, but also in Bulgaria (Temnata TD2/6, Bacho Kiro 11), near Brno (Bohunician at Brno Bohunice, Stránská skála Ss-IIIa-4, Brno Líšeň , Tvarožná, and Želeč), in Moravia (Rataje, Ondratice, Mohelno) in the eastern Slovakia (Nižný Hrabovec), in the Ukraine,at Obi-Rakhmat Grotto, situated 100 km northeast of Tashkent in the Republic of Uzbekistan and in the Altai (Kara Bom). These ensembles date roughly between 45-32 k.a. BP.
A similar ensemble was found at a chert extraction site in the Nil-valley at Taramsa 1. During the Tarmasan “there was a clear tendency towards blade production from large cores, where, instead of obtaining a few Levallois flakes from each individual core, a virtually continuous process of blade production made it possible to create a large number of blades from each core” (Vermeersch and Hendrickx 2000, p.23).
A child burial was found at Taramsa-1 dating to this time (c.55 k.a BP): “The poorly preserved bones were those of a subadult ‘anatomically modern human’ similar in appearance to the Mechtoid populations of the north African Epipalaeolithic. The position of the body, as well as the depth of the pit in which it was found . . . suggest that the child had not died in this location but had been deliberately brought here to be buried” (Midant-Reynes 1992/2000 p.37).
There is a broad agreement that in the Levant, the Emirian evolved to the Ahmiran at about 42-35 k.a. BP (Ksar ‘Akil Rockshelter, Üçağızlı Cave, Kebara Cave) and may have consecutively diffused to Europe as early as 40-42 k.a. BP (the so called “Protoaurignacian” of southern Europe).
