Lomekwi 3

Lomekwi 3 is an archaeological site in Kenya where stone tools dating to about 3.3 million years ago were discovered. The tools predate the earliest known members of the genus Homo.

Lomekwian: The archaeological industry associated with the stone tools discovered at Lomekwi 3. This name identifies the toolmaking tradition represented by the site’s finds.
Stone knapping: The deliberate shaping of stone by striking it with another object to detach flakes. The Lomekwi artifacts are interpreted as products of this activity.
Sonia Harmand: A French archaeologist who led the research team that reported the Lomekwi 3 tools. Her team published the site’s tools as evidence of very early stone technology.
Kenyanthropus platyops: An extinct hominin species known from fossils discovered west of Lake Turkana in Kenya. Its fossils occur near the site in time and geography, but no toolmaker is established.
Lomekwi 3 hammerstones: Large stones from Lomekwi 3 interpreted as tools used to strike other stones or materials. Their impact marks and forms help reconstruct how tools were used.
Percussion flaking: A stoneworking technique in which an implement is struck against a core to detach a flake. This technique explains the sharp removals visible on Lomekwi cores.
Jason Lewis: An anthropologist whose research includes early hominin behavior and the Lomekwi 3 discoveries. He co-authored the study that introduced the site’s tool assemblage.
Australopithecus afarensis: An extinct hominin species known from eastern Africa between roughly 3.9 and 2.9 million years ago. It is one possible broader comparison for hominins living when Lomekwi tools were made.
Lomekwi 3 cores: Stone artifacts from Lomekwi 3 bearing removals made by striking flakes from a core. These artifacts provide evidence for deliberate stone reduction at the site.
Conchoidal fracture: A curved fracture pattern produced when brittle materials such as flint break under impact. Fracture features help distinguish intentional flaking from accidental breakage.
