Starting in the grasslands of the rift, Homo erectus, the predecessor of modern humans, found an ecological niche as a tool-maker and developed a dependence on it, becoming a "tool equipped savanna dweller." Archaeological discoveries in Kenya in 2015, identifying possibly the oldest known evidence of hominin use of tools to date, have indicated that Kenyanthropus platyops ( a 3.2 to 3.5-million-year-old Pliocene hominin fossil discovered in Lake Turkana, Kenya in 1999 ) may have been the earliest tool-users known.
Prior to the discovery of these "Lomekwian" tools, the oldest known stone tools had been found at several sites at Gona, Ethiopia, on the sediments of the paleo-Awash River, which serve to date them.
From the dawn of our species to the present day, stone-made artefacts are the dominant form of material remains that have survived to today concerning human technology.
Burin This artifact was used for carving bone, antler, or wood.
Blade cores provided a portable source of stone or obsidian for manufacturing different kinds of tools by flaking off pieces from the core.
The basis of many Upper Paleolithic tool forms from both the Old and New Worlds was the blade flake, a thin, parallel-sided flake that is at least twice as long as it is wide.
For European and American Stone Age peoples, end scrapers served as heavy- duty scraping tools that could have been used on animal hides, wood, or bones.
Once the hide was removed from an animal, an end scraper could take the hair off the skin's outer layer and remove the fatty tissue from its underside.
