1The Trans-Evol project (Early to Middle Pleistocene Transition: Evolution and diversity of African hominin fossil populations) is a collaboration between the CNRS, the National Museums of Kenya and the University of Cambridge. The project is opening new archaeological excavations in West-Turkana (Kenya) to document the behavioural, cognitive and morphological diversity of hominin populations during the Early to Middle Pleistocene Transition (EMPT 1250-750 ka). This period is characterised by major environmental changes along with behavioural, cognitive (Acheulean diversification/expansion, predetermined production) and morphological (encephalisation) innovations within the genus Homo. Unfortunately, the EMPT African fossil record is scarce and poorly correlated with the archaeological record. In 2017, four new West-Turkana sites were identified. Geological mapping and preliminary dating of one of these (Kanyimangin) point towards an EMPT age. Since then, 280 archaeological materials were recorded among which lithic artefacts which characteristics (e.g. bifaces and retouched flakes) point towards the Acheulean. Additionally, fossils belonging to a range of extinct species were also discovered, such a Euthecodon brumpti, a crocodile which would have disappeared around 1 million years ago and Loxadonta adaurora which would have disappeared around 500,000 years ago. Finally, volcanic ash layers were found near Kanyimangin. Their analysis will contribute to the chronological characterisation of the entire Turkana Basin. This poster will present in more details the relevance of the Kanyimangin site for hominin evolution at the EMPT and introduce the results of the next field season taking place in October 2021.
