We discovered fossil wood in place in the Upper Miocene layers in Kenya.
We studied anatomically the fossil wood and identified them partly.
The cambial activity of all the fossil wood reveals a past seasonal climate.
The discovered palaeoflora is potentially close to the extant flora found in the Tana River valley in Eastern Kenya.
The present environment of the Tugen Hills is cooler than the paleoenvironment of the fossil site due to the Hills uplift.
