Hominin presence is well documented in a number of Early Pleistocene and early Middle Pleistocene European localities. However, the evidence currently available indicates that Acheulean handaxes spread in the fluvial basins of Western Europe during MIS 11, ~400 kyr ago, associated with Homo heidelbergensis, although a number of early Middle Pleistocene Acheulean assemblages have been dated from MIS 16 onwards. For this reason, the magnetostratigraphic dating in Southeast Spain of two archaeological localities, the open-air site of Solana del Zamborino (SZ) and the rock-shelter site of Cueva Negra del Estrecho del Quípar (EQ), that put back the appearance of handaxes to the Early-Middle Pleistocene limit (Scott and Gibert, 2009) is of particular interest, as the new ages suggest that H. heidelbergensis was a contemporary of H. antecessor that had the ability to produce Levallois debitage and to control fire during the Early-Middle Pleistocene transition. However, we have detected a number of errors in the interpretation of the archaeological assemblage from the first site as well as striking discrepancies with the original faunal lists published for both localities, with several large mammal species that are omitted or arbitrarily changed to make the assemblages consistent with the new ages deduced from magnetostratigraphy. For this reason, we suggest that: (1) the finding of reverse polarity in the sediments sampled for paleomagnetism in SZ may simply record one of the polarity reversals that took place during the Brunhes Chron, although the use by Scott and Gibert (2009) of a composite stratigraphic column precludes correlating these levels with a specific reversal; and (2) the fauna and tools of EQ correspond to the late Middle Pleistocene sedimentary infillings of this karst site, while the samples taken for paleomagnetism belong to a previous sedimentary cycle during the Matuyama Chron. Such interpretations would be in better agreement with the age estimates provided by biostratigraphy and also with the currently accepted chronology for the appearance of Acheulean industries in Western Europe.  相似文献

Reccopolis was a new urban foundation of the late sixth century AD, built by King Liuvigild during the period of the Visigothic state formation. The city was equipped, alongside other facilities, with an aqueduct built ex novo in the Roman technique. This has only recently been studied. The construction of a new city and a new aqueduct indicates a great economic effort by the Visigothic ruler: the event was in itself also a grand act of propaganda in addition to its obvious functional purpose. The aqueduct is itself unmatched in public constructions of this period.  相似文献

The article reports on the street protests that took over Spanish cities earlier in May and June. The protests have been explained as a response on the part of new media democratic networks to the governance of the economic crises by corrupt political and financial classes. We offer here a tentative chronology of the events, and essay instead an argument about a revitalised municipalist tradition, that sees in the plaza the centrepiece of new forms of do‐it‐yourself political action.  相似文献

A synoptic view and interpretation of archaeological material from the mesolithic to the end of the Iron Age is provided, and this is viewed in the context of available palaeoenvironmental information. The evidence of various settlement forms suggests that mesolithic folk occupied the region for a long period, but their environmental impact appears to have been low although not negligible. In neolithic times a probably higher population density was capable of more thorough changes of vegetation but the total permanent alteration of ecosystems is thought to be small. Evidence for settlement is entirely inferential. By contrast, the Bronze and Iron Ages were periods of considerable clearance of forest and subsequent ecological changes like the leaching of soils increased, and traces of settlement are plentiful. New data on Iron Age settlements shows a downward movement of settlement sites and some Celtic fields are noted, though they are sparse compared with other uplands in Great Britain. A number of unanswered questions are posed, mostly about the nature of the settlement pattern in mesolithic, Bronze Age and Iron Age times. No complete synthesis of archaeological and palaeoenvironmental data is yet possible at this scale but certain parts of the moors have a high potential for reconstructing prehistoric geography.  相似文献
