Stone tools at both sites were simple Mode 1 technology or Oldowan-style and made from local raw materials. Tools included simple cutting flakes, lacking the more sophisticated tools found elsewhere at this time. At Sima del Elefante the cave seemed to be a tool knapping site, with flakes showing clear evidence of manufacturing techniques - artefacts were detached by direct hammer percussion on hand-held medium-sized cores. The absence of retouched tools at this site, along with the nature of the tool kit, suggests that the tools were created mainly for processing and eating meat and marrow. - See more at: http://australianmuseum.net.au/homo-antecessor#sthash.guNKqXr4.dpuf
