Middle Pliocene Bovidae from Hominid-bearing Sites in the Woranso-mille Area, Afar Region, Ethiopia
Hominid-bearing sites of the north western part of the Woranso-Mille research area, dated to between 3.7 and 3.8 Ma., yield 10 species of Bovidae. The evolutionary stages of the most common species fit quite well this radiometric age. The most abundant bovid is a new species of Aepyceros, of large size, with upright, lyrated horn-cores; it is clearly distinct from the impalas of younger sites i...
متن کاملPhylogeny of early Australopithecus: new fossil evidence from the Woranso-Mille (central Afar, Ethiopia).
The earliest evidence of Australopithecus goes back to ca 4.2 Ma with the first recorded appearance of Australopithecus 'anamensis' at Kanapoi, Kenya. Australopithecus afarensis is well documented between 3.6 and 3.0 Ma mainly from deposits at Laetoli (Tanzania) and Hadar (Ethiopia). The phylogenetic relationship of these two 'species' is hypothesized as ancestor-descendant. However, the lack o...
متن کاملAn early Australopithecus afarensis postcranium from Woranso-Mille, Ethiopia.
Only one partial skeleton that includes both forelimb and hindlimb elements has been reported for Australopithecus afarensis. The diminutive size of this specimen (A.L. 288-1 ["Lucy"]) has hampered our understanding of the paleobiology of this species absent the potential impact of allometry. Here we describe a large-bodied (i.e., well within the range of living Homo) specimen that, at 3.58 Ma,...
متن کاملPorphyrin ‘‘Mille-Feuilles” photo-electrodes
A porphyrin ‘‘Mille-Feuilles” photo-electrode is fabricated layer-by-layer by deposition of anionic [zinc meso-tetrakis(p-sulfonato phenyl) porphyrin] (ZnTPPS ) and positively charged polypeptides on a 11-mercaptoundecanoic acid-modified gold electrode to form a photoactive film. This work demonstrates that it is possible to form 3D structures having regularly spaced layers of redox molecules. ...
