TL;DR: The discovery of Lomekwi 3 is reported, a 3.3-million-year-old archaeological site where in situ stone artefacts occur in spatiotemporal association with Pliocene hominin fossils in a wooded palaeoenvironment and the name ‘Lomekwian’ is proposed, which predates the Oldowan by 700,000 years and marks a new beginning to the known archaeological record.

TL;DR: In this paper, an interdisciplinary approach combining techno-typological, refit, use-wear and GIS studies of experimental anvils from Olduvai Gorge (Tanzania) was pursued to establish protocols of analysis of battered tools, and the main aim was to classify types of damage on battered artefacts according to the percussive task performed.

TL;DR: The results demonstrate the heuristic potential of combined suites of GIS techniques for the analysis of battered artifacts, and have enabled creating a referential framework of analysis in which wild chimpanzee battered tools can for the first time be directly compared to the early archaeological record.

TL;DR: The Middle Pleistocene archaeological sequence, attributed to the late Acheulean, is introduced, which would make this sequence among the latest evidence of the Acheulesan in East Africa, in a time span when the Middle Stone Age is already documented in the region.

TL;DR: Comparison of two assemblages of pounded objects from excavations at HWK EE and EF-HR helps provide a wider picture of pounding activities during the Oldowan-Acheulean transition at Olduvai Gorge.
