On a Pleistocene human occupation at Pedra Furada, Brazil
The last decades of fieldwork have not decisively upset the long-held view that the settlement of the Americas occurred in the very latest Pleistocene, as marked in North America by the Clovis archaeological horizon at about 11,200 years ago, and by a variety of contemporaneous South American industries. Yet there are several sites that may prove to be older, among them Pedra Furada, in the tho...
متن کاملSYNGENETIC STRONTIUM ORE DEPOSITION AT THE BASE OF ASMARI FORMATION, BANGESTAN ANTICLINE, BEHBAHAN, IRAN
Detailed petrographic, geochemical and strontium isotope studies, combined with field observation and rnicrofacies investigations indicate that syngenetic celestite at the base of Asmari Formation at the Bangestan anticline, Behbahan region, was deposited directly from Tertiary seawater in an intrasupratidal to supratidal environment. During diagenesis, the precipitated celestite underwent ...
متن کاملMicrobiostratigraphy of Middle Eocene ShahbazanFormation at the southeastern flank of Chenar Anticline,Lurestan Basin, Sw Iran
In this research, biostratigraphy related to the carbonate succession of the Shahbazan Formation at the southeastern flank of Chenar anticline, Lurestan Basin, is discussed. A study of large benthic foraminifera from the 294 mthick Shahbazan Formation led to the identification of two Middle Eocene biozones: Somalina sp. Zone, Nummulites-Alveolina Assemblage Zone. The age of the Shahbazan Format...
متن کاملHominin Footprints from Early Pleistocene Deposits at Happisburgh, UK
Investigations at Happisburgh, UK, have revealed the oldest known hominin footprint surface outside Africa at between ca. 1 million and 0.78 million years ago. The site has long been recognised for the preservation of sediments containing Early Pleistocene fauna and flora, but since 2005 has also yielded humanly made flint artefacts, extending the record of human occupation of northern Europe b...
متن کاملIsotopic evidence for Plio^Pleistocene environmental change at Gona, Ethiopia
A 4.5 Ma record of fluvial and lacustrine deposits is well exposed at Gona, in the Afar Depression of Ethiopia. We use isotopic values of pedogenic carbonate and fossil teeth to reconstruct Plio^Pleistocene environmental change at Gona. An increase in N13C values of pedogenic carbonates since 4.5 Ma points to a shift from woodlands to grassy woodlands in the early Pliocene, 310.4 to 33.9x (VPDB...
