Around the same time, H. De Terra and T. T. Paterson, working in northwest India as part of the Yale–Cambridge Expedition, placed Stone Age cultures within stratigraphic sequences associated with a sequence of river terraces, which in turn were correlated with Alpine glaciations. This scheme...

a Stone Age, was formally articulated by Christian Thomsen when he organized the exhibits of the Danish National Museum in the early nineteenth century. By the time Sir John Lubbock (1834–1913) publishedPrehistoric Timesin 1865, the Stone Age in Europe was considered to have two phases:période...

The maintenance of a near-perpendicular (75–90°) exterior platform angle, through successive tablet removals (total and partial), is a common feature however—with acute exterior platform angles on both cores and debitage being very uncommon (Bachellerie, 2011; Bodu et al., 2017; Connet, ...
convexities are cortical, taking advantage of the natural morphology of the block, or created and maintained through the opportunistic detachment of flakes from the striking platform or the débitage surface. The exploitation of a large part of the block is aimed at the production of large blades...
but one apparently well worth the effort. They note that other grinding stones dating back to roughly the same time frame have been found before, but they were used to grind roots and cattails—they suspect more study will result in finding that more stones were used to grind grains as well...
Using our archaeological site database (n = 2465), which includes both spatial and temporal data, we then assigned each site (i) temporally to the century time slice of data for the CHELSA TraCE21k data using its median calibrated age rounded to the nearest century and (ii) spatially ...
particularly those made from ostrich eggshell in Southern and East Africa during the Later Stone Age (LSA)26,27,28,29,30. The picture is drastically different in Eurasia where, from 45 ka cal BP onward, the first uncontroversial personal ornaments show substantial variations in shape, color and...
etc. It is also difficult to pinpoint the age of these localities in the Middle Paleolithic timeframe. Among the stratified sites with buried cultural layers is a group of camps of the so-calledtravertinetype (the sites of Koshkurgan I-II, Shoktas I-III), located in the piedmont areas ...
