Date Time Toolkit of Prehistoric Humans Prof. Ran Barkai producing a replica of a chopping tool in order to be used in experimental marrow extraction. Researchers from the Sonia and Marco Nadler Institute of Archaeology at Tel Aviv University unraveled the function of flint tools known as ‘chopping tools’, found at the prehistoric site of Revadim, east of Ashdod. Applying advanced research methods, they examined use-wear traces on 53 chopping tools, as well as organic residues found on some of the tools. They also made and used replicas of the tools, with methods of experimental archaeology. The researchers concluded that tools of this type, found at numerous sites in Africa, Europe and Asia, were used by prehistoric humans at Revadim to neatly break open bones of medium-size animals such as fallow deer, gazelles and possibly also cattle, in order to extract the nutritious high-calory bone marrow.
