Nyayanga

Nyayanga is a Lower Paleolithic period site containing artifacts and fossils dated to 3.032-2.595 million years ago. Nyayanga is one of the oldest Oldowan localities discovered to date, and over 1,776 fossils and 330 artifacts have been recovered from the top half of its NY-1 layer, which roughly dates to 3-2.6 million years ago. Recent excavations include the Homa Peninsula Paleoanthropological Project's excavations from 2016 to 2023 yielding 272 NY-1 layer artifacts and a July 2025 project uncovering tools believed to be older than 2.6 million years. Oldowan artifacts at Nyayanga have been found in context with Paranthropus teeth as well as bovid and hippopotamid skeletal remains. Furthermore, many of the stones used in the construction of these tools were selectively sourced from over 10 km away. These findings indicate the Oldowan was developed and used over a wider area and that long-distance stone transport began earlier in the line of human evolution than previously thought.
