Namilamadeta snideri new genus and species, from the medial Miocene Namba Formation, was found on the western side of Lake Tarkarooloo, South Australia. It is tentatively assigned to the Wynyardiidae and may be the plesiomorphous sister group of the Vombatidae. 相似文献

Following earlier examples of mapping the subsurface of shell bearing sites using augering, we employ percussion coring to identify early Holocene shell midden components at two types of sites on the Northwest Coast of North America. We describe a method for mapping subsurface components at shell bearing sites including basal deposits, paleosols and transitions between distinct cultural components. Our research was undertaken for the purpose of identifying early Holocene shell middens above the modern shore, and as components below large shell midden villages. Our results augment the developmental trajectory of shell middens on the Northwest Coast by suggesting that pre-5000 BP forms of these sites may be more common than previously thought. In light of these results, we argue that the Northwest Coast cultural historical sequence, which locates an increase in the number and rate of accumulation of shell middens beginning 5000 years ago, to be premature. However, there are insufficient data from shell middens in the early Holocene, a sampling problem that the percussion coring methods described here can address. 相似文献

Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS) is applied to the study of four samples of opaque glass of Late Bronze Age date. The technique is uniquely capable of identifying compositional heterogeneity at a sub-micron resolution within the crystalline opacifiers dispersed through homogeneous glass matrices. It is shown that this provides crucial information on the possible raw ingredients of the opacifying inclusions used, and has the potential for highlighting regional variations in the production technology involved in creating different colours of opaque glass. 相似文献

Trace element compositions of 25 shards of Chinese Late Ming export blue-and-white porcelain from Zhangzhou and Jingdezhen kilns are analysed by Inductively Coupled Plasma Mass Spectrometry. Principle components analysis and REE distribution curves are used to establish method for provenance unknown Chinese export blue-and-white porcelain which may have originated from Zhangzhou or Jingdezhen kilns. By matching the REE distribution curves of Zhangzhou kiln samples and parent rocks of the possible clay sources used to make Zhangzhou blue-and-white, and comparing it with previous results of geological, geochemical and archaeological researches, the clay used for producing Zhangzhou export blue-and-white has been identified as having been collected from the weathered shells of a nearby potassium feldspar miarolitic granite outcrop. 相似文献

Tin, as a constituent of bronze, was central to the technological development of early societies, but cassiterite (SnO2) deposits were scarce and located distantly from the centres of Mediterranean civilizations. As Britain had the largest workable ore deposits in the ancient Western world, this has led to much historical speculation and myth regarding the long-distance trading of tin from the Bronze Age onwards. Here we establish the first detailed chronology for tin, along with lead and copper deposition, into undisturbed ombrotrophic (rain-fed) peat bogs located at Bodmin Moor and Dartmoor in the centre of the British tin ore fields. Sustained elevated tin deposition is demonstrated clearly, with peaks occurring at 100–400 and 700–1000 calendar years AD – contemporaneous with the Roman and Anglo-Saxon periods respectively. While pre-Roman Iron Age tin exploitation undoubtedly took place, it was on a scale that did not result in convincingly enhanced deposition of the metal. The deposition of lead in the peat record provides evidence of a pre-Roman metal-based economy in southwest Britain. Emerging in the 4th century BC, this was centred on copper and lead ore processing that expanded exponentially and then collapsed upon Roman colonization during the 1st century AD. 相似文献

ABSTRACTScholars know Hawai‘i’s “minister of everything” as an upstart who rose to prominence by defending Hawaiian sovereignty. Few have noticed that Walter Murray Gibson’s influence stemmed from a paternalistic campaign to improve Islander health and expand the labor force for an emerging plantation complex. Improbably, public health presented Gibson, an excommunicated Mormon missionary, with a platform to pursue his lifelong dream of ruling a Pacific empire. This article explores the entangled issues of health, labor, and empire amid disparate and unpredictable colonial incursions in the Hawaiian Islands after 1860. 相似文献

Evidence for the development of London’s riverside settlement c. AD 1000–1200 was found on the east edge of an important dock known successively as Æthelred’s hithe and Queenhithe. A sequence of embankments and tree-ring dated revetments advanced the waterfront nearly 40 m into the Thames and small inlets provided access to the foreshore. Building and rebuilding took place on a row of properties, with up to a dozen buildings identified; after c. 1150, passages were created for two narrow lanes connecting Thames Street with the quays and foreshore. Important reused building and ships’ timbers and dated groups of metalwork and other artefacts were recovered from the waterfronts. 相似文献

The southern African MSA comprises a series of phases of unique technological innovations that fuel current models on the evolutionary processes of Anatomically Modern Humans. However, the nature and variability of these technological phases remain poorly documented. This study reports on the previously unpublished sequence of Diepkloof Rock Shelter (South Africa) and investigates the main technological changes therein, particularly emphasizing the emergence, succession and disappearance of the Still Bay (SB) and the Howiesons Poort (HP). We argue for technological change that occurred at different rates and under the influence of variable driving factors. Our model implies that the SB and the HP are not related to the influx of new populations but have regionally specific origins. Unlike the other techno-complexes, the HP at Diepkloof is subdivided into different phases (Early, Intermediate and Late) but only the upper phases resemble the so-called “classic” HP. Finally, the technological sequence of Diepkloof questions the homogeneous picture which has been so far assumed for the southern African MSA and places emphasis on the importance of exploring long regional sequences. 相似文献

The ‘South Division of the County of Kerry’ (GSI FS 1.2.001) is a copy of the southern half of a lost late eighteenth / early nineteenth century map of County Kerry, in southwestern Ireland. Geological annotations on the map are traced to specific episodes (c.1820, 1838 and 1844) in the unofficial geological survey of Ireland conducted by Richard (later Sir Richard) Griffith between 1811 and 1855. The Griffith provenance of the map is part of the evidence used to identify the ‘South Division of the County of Kerry’ as a derivative of the now lost Grand Jury map of Kerry made by the American émigré artist and cartographer Henry Pelham. 相似文献
