Abstract
The fragmentation observed in an archaeological site, which cannot be explained only in terms of anthropological action, we subjected faunal remains (bones and teeth) in alternations of frost/thaw at the center of geomorphology of the CNRS of Caen. At the same time, we arranged osseous and dental fragments in five cells of an artificial site in natural environment in the South Alps (program of multidisciplinary research transfert de référentiels actuels de l’étage nival aux sites paléolithiques [TRANSIT]). At the end of the experiments, we were able to bring to light the characteristics of some gelifracts but their direct comparison with the archaeological osseous fragments, although very promising, is there only for its debuts and requires others similar experiments.
