Rice rats (Sigmodontinae: Oryzomyini) are abundant in the Late Quaternary fossil record and in Holocene pre-Columbian archaeological middens across the Lesser Antilles. All of these rice rats are now extinct, and their regional diversity and systematics remain extremely poorly understood. We redescribe all of the region's rice rat taxa known from adequate diagnostic material (Megalomys desmarestii, Megalomys luciae, and Oligoryzomys victus), and describe a new genus and species, Pennatomys nivalis gen. et sp. nov., from archaeological sites on St. Eustatius, St. Kitts, and Nevis, which formed a single larger island during Quaternary low sea-level stands. Cladistic analysis supports the inclusion of O. victus within Oligoryzomys, and identifies Megalomys as a sister group of the large-bodied genera Sigmodontomys or Sigmodontomys + Nectomys, suggesting that large body size in Megalomys represents phyletic gigantism rather than 'island gigantism'. Megalomys and Pennatomys belong to an oryzomyine clade that has undergone remarkable radiation throughout the oceanic and continental-shelf islands of the Neotropical region, but these genera do not represent a monophyletic group within the Nectomys subclade, indicating multiple over-water colonization events of the Lesser Antillean island chain. Although Lesser Antillean rice rats were heavily exploited by prehistoric Amerindians, it is likely that most or all of these taxa survived until European arrival in the region.
Excavations at Hartshill Copse in 2003 uncovered evidence for Late Bronze Age settlement, securely dated to the 10th century BC, associated with long alignments of closely set posts: prehistoric landscape features with few known parallels. Extensive sampling of the settlement remains yielded quantities of burnt flint and plain Post Deverel-Rimbury potsherds, and, quite unexpectedly, a substantial quantity of iron hammerscale. This paper presents the excavation data, with supporting dating evidence, and the results of detailed analysis of the metallurgical residues. It explores the spatial distribution of artefact types within the settlement, and presents an interpretative model for settlement use. The nature of the settlement, with its carefully planned use of space and close relationship with the post alignments, is then discussed. Together, all this provides conclusive evidence for the earliest ironworking site yet recognised in Britain. The paper concludes with a comprehensive discussion of early ironworking in its British and European context.
This paper questions whether the current model of hillforts as central places for the control and redistribution of goods in Iron Age Britain is appropriate by reviewing the evidence for the production and distribution of both pottery vessels and salt in ceramic containers. Suitable data found in published reports of excavations from all parts of Britain are considered, if available, and the information is synthesized by defined region and broad phase.
s 225 baseline levels. Pressure studies were done under relatively isometric, not open manometric, conditions. Studies done with the ventricular fluid system open to flow at various levels of pressure show an early increase and a delayed decrease in cerebrospinal fluid formation with acetazolamide compared to a decrease in flow following isosorbide.
