Goda Buticha is a newly discovered cave site in southeastern Ethiopia, containing MSA and LSA cultural material, faunal remains, beads, and human skeletal remains. A 2.3m-deep sedimentary sequence records two occupational phases separated by a sharp chronological hiatus, in the Upper Pleistocene (~43-31.5 ka cal BP) and in the mid- Holocene (7.8-4.7kacalBP). Faunal remains suggest changes in paleoecological conditions that are in agreement with patterns documented in regional speleothem-based reconstructions. The lithic assemblage at the base of the sequence is clearly MSA, with Levallois production, unifacial and bifacial points, relatively large debitage and use of local raw materials, associated with a microlithic component. The overlaying LSA assemblage contains diagnostic artifacts (backed microliths and bladelet production), with ubiquitous use of obsidian and MSA elements that appear in the Holocene. In the absence of indications for post-depositional mixture, the apparent cultural continuity of MSA elements from the Upper Pleistocene into the Middle Holocene at Goda Buticha may represent yet another variation of the elusive MSA/LSA transition. Goda Buticha is a key site for reevaluating the dynamics and tempo of this transition in eastern Africa.
