A basic distinction is that between flaked or knapped stone, the main subject here, and ground stone objects made by grinding. Flaked stone reduction involves the use of a hard hammer percussor, such as a hammerstone, a soft hammer fabricator (made of wood, bone or antler), or a wood or antler punch to detach lithic flakes from the lithic core ...
Other forms of quern-stone include hopper-rubbers and Pompeian mills, both used by the Romans. The larger rotary mills were usually worked by a donkey or horse via an extension arm of wood attached to the upper stone. Sound of a Roman mill. Querns utilizing crank-and-connecting rods were used in the Western Han Dynasty. [26]

A rock shelter (also rockhouse, crepuscular cave, bluff shelter, or abri) is a shallow cave-like opening at the base of a bluff or cliff. In contrast to solutional caves , which are often many miles long or wide, rock shelters are almost always modest in size and extent.
The log structure was made at least 476,000 years ago, while the wood tools are slightly younger, under 400,000 years old. That places the materials in a time before our species, Homo sapiens ...
Found in Europe and often belonging to the later Bronze Age or Iron Age. [11] Often marked on Ordnance Survey maps in the UK. [12] Ridge and furrows are sets of parallel depressions and ridges in the ground formed primarily through historic farming techniques. [13] Mottes are mound structures made of earth and stone that once held castles.
The earliest stone tools to date have been found at the site of Lomekwi 3 (LOM3) in Kenya and they have been dated to around 3.3 million years ago. [1] The archaeological record of lithic technology is divided into three major time periods: the Paleolithic (Old Stone Age), Mesolithic (Middle Stone Age), and Neolithic (New Stone Age). Not all ...
The age of these man-made structures is difficult to ascertain, but generally they are believed to have been produced in the Bronze Age and Upper Paleolithic although some, for example in North America and Europe, were generated at a later date.
