A premature burial: comments on Grayson and Meltzer’s “Requiem for overkill”
In a recent JAS article (“A requiem for North American overkill”), Donald Grayson and David Meltzer [39] attack Paul Martin’s “overkill” hypothesis that humans caused America’s Terminal Pleistocene megafaunal extinctions. This is one of three similar recent articles by these authors [37–39] in which, by scrupulous evaluation of the archaeological record, they have reduced the list of unambiguou...
متن کاملBedforms and Mine Burial
The generation and migration of bedforms (eg, ripples, megaripples and sand bars) on sandy bottoms in the nearshore (0-8 m water depths) provides a mechanism for objects on the seafloor to become buried. As a bedform migrates past a mine, the mine will fall to the low point of the bedform trough before subsequently being buried by the passage of the following bedform crest. The statistics of mi...
متن کاملHypothermia during Avalanche Burial
Core body temperature cooling during avalanche burial results in hypothermia, and further core temperature cooling during extrication and evacuation of an avalanche burial victim may result in more severe hypothermia. We performed two studies measuring the rate of core body temperature cooling during snow burial and after extrication from snow burial. Subjects were completely buried in a large ...
متن کاملBedform Dynamics and Mine Burial
Large bedforms in the nearshore (with heights of 10 – 50 cm and lengths of 1-10 m) are observed to occur frequently and to be ubiquitous throughout the surf zone (e.g., Clifton et al. 1971, Gallagher et al. 2002, Hay and Wilson 1994, Thornton et al. 1998). However, their dynamics are poorly understood and they are generally neglected in models of sediment transport, morphology change and nearsh...
متن کامل1Residential Burial in Global Perspective
While the study and interpretation of mortuary practices have long been important parts of archaeological analyses, rarely has residential burial – the practice of burying the deceased in and around houses – been a specific focus of investigation. Here, we examine some of the global contexts in which residential burial has occurred and discuss the different ways that archaeologists have interpr...
