Selection of rocks for stone tool making at Lokalalei Oldowan sites
Significance: Reveals important differences in the way that hominins chose rocks for toolmaking at nearby sites around 2.3 million years ago.
Stratigraphy and environment of Lokalalei Oldowan sites
Significance: Refines the age difference between two important Lokalalei oldowan tool sites and the evidence for the nearby environments.

The oldest known Acheulean technology
Significance: 1.76 million year old biface tools from the Kokiselei 4 site provide a new start-date for this long-lived toolmaking tradition.
The Acheulean elephant butchery site of Nadung’a 4
Significance: Abundant stone tools found alongside the 700 thousand year old remains of a large elephant and may have been used to butcher it.

Reports the oldest known fossil of the genus Homo in West Turkana
Significance: Important morphological and behavioural changes  are associated with the emergence of the genus Homo, which is shown to be present in Turkana around 2.3 million years ago.
West Turkana early stone tool makers favoured woody habitats
Significance: Analysis shows stone tool sites dated between 2.4 and 1.4 million years old were located near to tree cover, contrasting the traditional idea that hominins favoured open savannas.
