Expanded geographic distribution and dietary strategies of the earliest Oldowan hominins and Paranthropus
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 …

Ecological shifts and hominin adaptations during the Mid-Pleistocene Climate Transition in Northeast Asia as evidenced by isotopic analysis (δ13C, δ18O) of …
Abstract The Nihewan Basin in North China is one of the most important early
archaeological sequences for our understanding of the ecological ranges exploited by …

Earliest Olduvai hominins exploited unstable environments~ 2 million years ago
Rapid environmental change is a catalyst for human evolution, driving dietary innovations,
habitat diversification, and dispersal. However, there is a dearth of information to assess …

Bone tools from Beds II–IV, Olduvai Gorge, Tanzania, and implications for the origins and evolution of bone technology
The advent of bone technology in Africa is often associated with behavioral modernity that
began sometime in the Middle Stone Age. Yet, small numbers of bone tools are known from …

The Pleistocene high-elevation environments between 2.02 and 0.6 Ma at Melka Kunture (Upper Awash Valley, Ethiopia) based upon stable isotope analysis
Pleistocene environments are among the most studied issues in paleoecology and human
evolution research in eastern Africa. Many data have been recorded from archaeological …

Carbon, nitrogen, and oxygen stable isotopes in modern tooth enamel: A case study from Gorongosa National Park, central Mozambique
The analyses of the stable isotope ratios of carbon (δ13C), nitrogen (δ15N), and oxygen
(δ18O) in animal tissues are powerful tools for reconstructing the feeding behavior of …

Hominin raw material procurement in the Oldowan-Acheulean transition at Olduvai Gorge
The lithic assemblages at the Oldowan-Acheulean transition in Bed II of Olduvai Gorge,
Tanzania, represent a wide variety of raw materials reflecting both the diversity of volcanic …

Relative abundance of grazing and browsing herbivores is not a direct reflection of vegetation structure: Implications for hominin paleoenvironmental reconstruction
The diet of fossil herbivores inferred from enamel stable carbon isotopes is often used to
make paleoenvironmental reconstructions. While many studies have focused on using …
