Modern African ecosystems as landscape-scale analogues for reconstructing woody cover and early hominin environments
Paleoenvironments represented by the sediments of the Early Pliocene Mursi Formation, Omo Valley, Ethiopia
Paleontology and Geology of the Mursi Formation
The importance of the Turkana Basin (northern Kenya) and lower Omo Valley (southern Ethiopia) in our understanding of the environments in which early hominins lived, and on how climate changes may have influenced the emergence and disappearance of species, is undeniable (e.g., Bobe and Leakey, 2009; Levin et al., 2011). The majority of the Plio-Pleistocene sediments belong to the Omo Group, which consists of the Shungura, Usno, Nkalabong, and Mur…
The environments of Australopithecus anamensis at Allia Bay, Kenya: A multiproxy analysis of early Pliocene Bovidae
Dietary flexibility of Australopithecus afarensis in the face of paleoecological change during the middle Pliocene: Faunal evidence from Hadar, Ethiopia
A 2500-Yr late Holocene multi-proxy record of vegetation and hydrologic changes from a cave guano-clay sequence in Sw Romania
We provide sedimentological, geochemical, mineral magnetic, stable carbon isotope, charcoal, and pollen-based evidence from a guano/clay sequence in Gaura cu Muscă Cave (SW Romania), from which we deduced that from ~ 1230 BC to ~ AD 1240 climate oscillated between wet and dry. From ~ 1230 BC to AD 1000 the climate was wetter than the present, prompting flooding of the cave, preventing bats from roosting, and resulting in a slow rate of clay accum…
Digital data collection in paleoanthropology
Understanding patterns of human evolution across space and time requires synthesizing data collected by independent research teams, and this effort is part of a larger trend to develop cyber infrastructure and e‐science initiatives. At present, paleoanthropology cannot easily answer basic questions about the total number of fossils and artifacts that have been discovered, or exactly how those items were collected. In this paper, we examine the me…

The Omo Mursi Formation: A window into the East African Pliocene
Isotopic evidence of early hominin diets
Carbon isotope studies of early hominins from southern Africa showed that their diets differed markedly from the diets of extant apes. Only recently, however, has a major influx of isotopic data from eastern Africa allowed for broad taxonomic, temporal, and regional comparisons among hominins. Before 4 Ma, hominins had diets that were dominated by C 3 resources and were, in that sense, similar to extant chimpanzees. By about 3.5 Ma, multiple homi…

Influence of Plio‐Pleistocene aridification on human evolution: Evidence from paleosols of the Turkana Basin, Kenya
New stable carbon isotope measurements, coupled with paleoprecipitation estimates, both from Plio‐Pleistocene paleosols of the Turkana Basin, Kenya, provide a high‐resolution record of aridification and increasing C 4 biomass during the past 4.3 Ma. This aridification trend is marked by several punctuations at 3.58–3.35, 2.52–2, and 1.81–1.58 Ma, during which the running mean and variance of δ 13 C and paleoaridity estimates increase, suggesting …
