Applying a wide and deep learning model to core-scan XRF data to reconstruct mineral assemblages for Pleistocene paleolake Olduvai, Tanzania
Paleolake coring initiatives result in large datasets from various proxies taken at different resolutions, ranging from continuous scans to samples collected at coarser intervals. Higher-resolution data (e.g., core-scan X-ray fluorescence [XRF]) can detect short-duration changes in the paleolake and help identify unit boundaries with precision; however, interpreting the causes of such changes may require sampling and more intensive laboratory ana…
Linking the tephrostratigraphy of the Pleistocene Naibadad Beds across the Laetoli area, Olduvai basin, and Ngorongoro volcano (Tanzania) using geochronology and tephra composition
While geological and paleoanthropological studies at Laetoli have focused on the relatively fossiliferous Ndolanya and Laetolil beds, Laetoli’s younger Naibadad and Olpiro beds provide an important record of Pleistocene volcanism, tectonics, and landscape evolution in northern Tanzania. This study documents the mineralogical and geochemical compositions of their tephra using EPMA of glass and phenocrysts, and their ages using 40 Ar/ 39 Ar geochro…

Geochemical “fingerprints” for Olduvai Gorge Bed II tuffs and implications for the Oldowan–Acheulean transition
Bed II is a critical part of early Pleistocene Olduvai Gorge, Tanzania. Its deposits include transitions from humid to more arid conditions (with associated faunal changes), from Homo habilis to erectus , and from Oldowan to Acheulean technology. Bed II (~ 1.8–1.2 Ma) is stratigraphically and environmentally complex, with facies changes, faulting, and unconformities, making site-to-site correlation over the ~ 20 km of exposure difficult. Bed II t…

Use of single-grain geochemistry of cryptic tuffs and volcaniclastic sandstones improves the tephrostratigraphic framework of Olduvai Gorge, Tanzania
Single-grain geochemical composition of volcaniclastic sandstones can be a potential tool to improve correlations of mixed pyroclastic/epiclastic deposits. To test this, trachytic tuffs of the paleoanthropologically important FLK, FLK N, and FLK NN sites of Pleistocene Olduvai Gorge Bed I (Tanzania) are used as an established tephrostratigraphic framework against which to test volcaniclastic sandstone correlations. Fluvio-lacustrine sandstones an…
The Origins of the Acheulean at Olduvai Gorge (Tanzania): A New Paleoanthropological Project in East Africa
The disappearance of the earliest human culture, the Oldowan, and its substitution by a new technology, the Acheulean, is one of the main topics in modern Paleoanthropology. Recent research has established that the Acheulean emerged originally in East Africa around 1.7-1.6 million years ago, and from that area expanded across the rest of Africa, Europe and parts of Asia. Despite the great relevance of the Oldowan-Acheulean transition, little is k…

Environments and hominin activities across the FLK Peninsula during Zinjanthropus times (1.84 Ma), Olduvai Gorge, Tanzania
Promise and pitfalls for characterizing and correlating the zeolitically altered tephra of the Pleistocene Peninj Group, Tanzania
The Pleistocene Humbu and Moinik formations of the Peninj Group in northern Tanzania preserve an important archaeological and paleontological record, in addition to a record of local volcanism in the form of tephra and lavas. Samples of the major Humbu and Moinik formations' basaltic and trachytic tephra were collected and characterized using phenocryst composition and both primary and authigenic mineral assemblage, since the volcanic glass was c…

Compositional and textural correlations between Olduvai Gorge Bed I tephra and volcanic sources in the Ngorongoro Volcanic Highlands, Tanzania
Fossil hominin ulnae and the forelimb of Paranthropus
The discovery of Pan in the Middle Pleistocene deposits of the Kapthurin Formation of the Tugen Hills (McBrearty and Jablonski: Nature 437 (2005) 105–108) inspires new interest in the search for other chimpanzee fossils in the East African Rift Valley. Craniodental evidence of an eastward excursion of chimpanzee populations in the Plio‐Pleistocene goes undetected in other hominin sites, but one enigmatic postcranial fossil, the Olduvai Hominid 36…
Late Pliocene Homo and Hominid Land Use from Western Olduvai Gorge, Tanzania
Excavation in the previously little-explored western portion of Olduvai Gorge indicates that hominid land use of the eastern paleobasin extended at least episodically to the west. Finds included a dentally complete Homo maxilla (OH 65) with lower face, Oldowan stone artifacts, and butchery-marked bones dated to be between 1.84 and 1.79 million years old. The hominid shows strong affinities to the KNM ER 1470 cranium from Kenya ( Homo rudolfensis …
