RT Journal Article T1 What comes after the Developed Oldowan B debate? Techno-economic data from SHK main site (Middle Bed II, Olduvai Gorge, Tanzania) A1 Sánchez Yustos, Policarpo A1 Díez Martín, Fernando A1 Díaz, Isabel A1 Fraile, Cristina A1 Uribelarrea Del Val, David A1 Mabulla, Audax A1 Baquedano, Enrique A1 Domínguez-Rodrigo, Manuel AB The Oldowan-Acheulean transition shows remarkable variability in Olduvai Bed II. To explain this, M. Leakey formulated a cultural model whose most distinctive contribution was the introduction of two cultural traditions (Developed Oldowan A and B) between the Oldowan and the Acheulean. This model has been discussed for the last fifty years, giving rise to the “Developed Oldowan B debate”. SHK is one of the very few sites that M. Leakey employed to characterize this cultural tradition. We present here a techno-economic analysis of the lithic assemblage recovered in a current excavation at this site that positively provides evidence of structured and complex techno-economic behavior. The results are consistent with the current and uncontested consensus about the Acheulean nature of the Developed Oldowan B. These results may also fuel a newly established debate.
