A normal magnetostratigraphic polarity interval in the Main Ethiopian Rift at 1.6 Ma: Implications for Acheulean and Homo erectus chronology
The timing of Homo erectus and Acheulean emergence in the Early Pleistocene is important to the understanding of the evolution of the genus Homo but is currently insufficiently resolved. Relevant chronologies are often based on a combination of radioisotopic dates and other age indicators such as magnetostratigraphy and biochronology. Here, we report a newly recognized normal magnetozone at ∼1.6 Ma in the Konso Formation, southern Main Ethiopian …
Quaternary tephra from the Valles caldera in the volcanic field of the Jemez Mountains of New Mexico identified in western Canada
A fine-grained, up to 3-m-thick tephra bed in southwestern Saskatchewan, herein named Duncairn tephra (Dt), is derived from an early Pleistocene eruption in the Jemez Mountains volcanic field of New Mexico, requiring a trajectory of northward tephra dispersal of ~1500 km. An unusually low CaO content in its glass shards denies a source in the closer Yellowstone and Heise volcanic fields, whereas a Pleistocene tephra bed (LSMt) in the La Sal Mount…
Ardipithecus ramidus and the Paleobiology of Early Hominids
Hominid fossils predating the emergence of Australopithecus have been sparse and fragmentary. The evolution of our lineage after the last common ancestor we shared with chimpanzees has therefore remained unclear. Ardipithecus ramidus , recovered in ecologically and temporally resolved contexts in Ethiopia’s Afar Rift, now illuminates earlier hominid paleobiology and aspects of extant African ape evolution. More than 110 specimens recovered from 4…
Ardipithecus Kadabba: Late Miocene Evidence from the Middle Awash, Ethiopia
Early Pleistocene Homo erectus fossils from Konso, southern Ethiopia
Homo erectus has been broadly defined to include fossils from Africa, Asia, and possibly Europe, or restricted to a supposedly confined Asian clade. Recently discovered fossils of H. erectus are allowing new insights into aspects of its evolution, such as the timing and mode of the species' emergence in Africa and its relationship to Asian populations. However, the currently available African record predating 1.0 Ma is poor, consisting of the Tur…

Imperial Ideology and Provincial Loyalty in the Roman Empire
"Imperial Ideology and Provincial Loyalty in the Roman Empire argues that the longevity of the empire rested not on Roman military power, but on a gradually realized consensus that Roman rule was justified. This consensus was itself the product of a complex conversation between the central government and its far-flung peripheries. Ando investigates the mechanisms that sustained this conversation, explores its contribution to the legitimization of…

African Homo erectus: Old Radiometric Ages and Young Oldowan Assemblages in the Middle Awash Valley, Ethiopia
Fossils and artifacts recovered from the middle Awash Valley of Ethiopia's Afar depression sample the Middle Pleistocene transition from Homo erectus to Homo sapiens . Ar/Ar ages, biostratigraphy, and tephrachronology from this area indicate that the Pleistocene Bodo hominid cranium and newer specimens are approximately 0.6 million years old. Only Oldowan chopper and flake assemblages are present in the lower stratigraphic units, but Acheulean bi…
