Journal ArticleDOI
Stratigraphic placement and age of modern humans from Kibish, Ethiopia
TL;DR: In this article, it was shown that the Omo I and Omo II hominid fossils are from similar stratigraphic levels in Member I of the Kibish Formation.
Journal ArticleDOI
Climate change and the collapse of the Akkadian empire: Evidence from the deep sea
Heidi Cullen,Peter B deMenocal,Sidney R. Hemming,G. Hemming,Francis H. Brown,Thomas P. Guilderson,Frank Sirocko +6 more
TL;DR: In this paper, a marine sediment core from the Gulf of Oman was used to study changes in regional aridity in Mesopotamia during the late third millennium B.C. They found a very abrupt increase in eolian dust and Mesopotamian aridity, accelerator mass spectrometer radiocarbon dated to 4025 ± 125 calendar yr B.P.
Journal ArticleDOI
Stratigraphic context of fossil hominids from the Omo group deposits: northern Turkana Basin, Kenya and Ethiopia.
TL;DR: The chronometric framework developed for Plio-Pleistocene deposits of the northern Turkana Basin is reviewed in light of recent advances in lithostratigraphy, geochemical correlation, paleomagnetic stratigraphY, and isotopic dating.
Journal ArticleDOI
High-temperature environments of human evolution in East Africa based on bond ordering in paleosol carbonates
Benjamin H. Passey,Naomi E. Levin,Naomi E. Levin,Thure E. Cerling,Francis H. Brown,John M. Eiler +5 more
TL;DR: It is shown that the Turkana Basin, Kenya—today one of the hottest places on Earth— has been continually hot during the past 4 million years, and the distribution of 13C-18O bonds in paleosol carbonates indicates that soil temperatures during periods of carbonate formation were typically above 30 °C and often in excess of 35 °C.
Journal ArticleDOI
New hominin genus from eastern Africa shows diverse middle Pliocene lineages.
Meave G. Leakey,Fred Spoor,Francis H. Brown,Patrick N. Gathogo,Christopher Kiarie,Louise N. Leakey,Ian McDougall +6 more
TL;DR: New fossils discovered west of Lake Turkana, Kenya, which differ markedly from those of contemporary A. afarensis point to an early diet-driven adaptive radiation, provide new insight on the association of hominin craniodental features, and have implications for the understanding of Plio–Pleistocene hom inin phylogeny.
