Expanded geographic distribution and dietary strategies of the earliest Oldowan hominins and <i>Paranthropus</i> Open
The oldest Oldowan tool sites, from around 2.6 million years ago, have previously been confined to Ethiopia’s Afar Triangle. We describe sites at Nyayanga, Kenya, dated to 3.032 to 2.581 million years ago and expand this distribution by ov…

Aridity and hominin environments Open
Significance Oxygen isotopes in modern and fossil mammals can provide information on climate. In this study, we provide a new record of aridity experienced by early hominins in Africa. We show that past climates were similar to the climate…

Hippopotamus (H. amphibius) diet change indicates herbaceous plant encroachment following megaherbivore population collapse Open
Megaherbivores (>1000 kg) are critical for ecosystem health and function, but face population collapse and extinction globally. The future of these megaherbivore-impoverished ecosystems is difficult to predict, though many studies have dem…

Dietary changes of large herbivores in the Turkana Basin, Kenya from 4 to 1 Ma Open
Significance Stable carbon isotopes give diet information for both modern and fossil mammals and can be used to classify diets as C 4 grazers, C 3 –C 4 mixed, or C 3 browsers. We show that diets of some major African herbivore lineages hav…
