DESCRIPTION:This talk will present results of fieldwork in Lower and Middl
 e Pleistocene sequences of Tanzania and Ethiopia\, which cover the emergen
 ce and disappearance of the Acheulean in East Africa. With regards to the 
 late Acheulean\, I will introduce the sequence of the Mieso valley (centra
 l-east Ethiopia)\, where 40Ar/39Ar suggest ages younger than 212 ka for so
 me of the Acheulean sites. The Mieso sequence also provides insights on th
 e technological variability existing during the late Acheulean\, in which 
 stratified assemblages show a strong fragmentation of chaines operatoires\
 , and demonstrate the variability of technological behaviours during the E
 ast African Middle Pleistocene. On the origins of the Acheulean\, this tal
 k will report recent archaeological excavations at the circa 1.5 Myr site 
 of EF-HR (Olduvai Gorge\, Tanzania). Renewed excavations at the main site 
 and nearby trenches have unearthed a considerably large new assemblage\, w
 hich enable reconstructing a detailed story of the paleoecological setting
 \, taphonomy and lithic technology. In addition\, our test-trenching appro
 ach has detected conspicuous differences in density of artefacts across th
 e landscape. In summary\, recent fieldwork has contributed new stratigraph
 ic\, technological\, and taphonomic data that should play a relevant role 
 in shaping an updated view of the Acheulean of East Africa\, which will be
  discussed within the context of the Africa record and beyond.
