<P> Paleolithic humans made tools of stone , bone , and wood . The early paleolithic hominins , Australopithecus , were the first users of stone tools . Excavations in Gona , Ethiopia have produced thousands of artifacts , and through radioisotopic dating and magnetostratigraphy , the sites can be firmly dated to 2.6 million years ago . Evidence shows these early hominins intentionally selected raw materials with good flaking qualities and chose appropriate sized stones for their needs to produce sharp - edged tools for cutting . </P>
