The stone tools may have been made by Australopithecus afarensis, the species whose best fossil example is Lucy, which inhabited East Africa at the same time as the date of the oldest stone tools, a yet unidentified species, or by Kenyanthropus platyops (a 3.2 to 3.5-million-year-old Pliocene hominin fossil discovered in 1999).
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).
The Levallois technique (IPA:) is a name given by archaeologists to a distinctive type of stone knapping developed around 250,000 to 400,000 [1] years ago during the Middle Palaeolithic period. It is part of the Mousterian stone tool industry, and was used by the Neanderthals in Europe and by modern humans in other regions such as the Levant. [2]
Stone tools preserve more readily than tools of many other materials. [ 1 ] [ 2 ] So the oldest tools that we can find in many areas are going to be stone tools. It could be that these tools were once accompanied by, or even preceded by, non-stone tools that we cannot find because they did not preserve.
Pressure flaking is a method of trimming the edge of a stone tool by removing small lithic flakes by pressing on the stone with a sharp instrument rather than striking it with a percussor. This method, which often uses punches made from bone or antler tines (or, among modern hobbyists, copper punches or even nails), provides a greater means of ...
In archaeology, ground stone is a category of stone tool formed by the grinding of a coarse-grained tool stone, either purposely or incidentally. Ground stone tools are usually made of basalt , rhyolite , granite , or other cryptocrystalline and igneous stones whose coarse structure makes them ideal for grinding other materials, including ...
