Pelegrin J., Texier P.-J. Les techniques de taille de la pierre préhistorique.
Abstract
Depuis les premiers outils taillés connus, vieux d'environ 2,6 millions d'années, jusqu'aux productions de la fin du néolithique ou de lâge du Bronze, nos ancêtres préhistoriques ont fait preuve d'une grande ingéniosité pour produire leurs outils de roches dures. Leur adresse manuelle s'est développée parallèlement à la compréhension et au contrôle des paramètres en jeu pour culminer avec le détachement par pression au levier de grandes lames parfaitement régulières.
... A) Angles less than 90 degrees are exploited when available. This is a general rule of fracture mechanics and has been documented in replicative flintknapping (Pelegrin and Texier 2004) as well as controlled experimentation (Dibble and Rezek 2009). Although hominins did not always follow this pattern (Delagnes and Roche 2005;Sahnouni et al. 1997), it is a generalized feature of most knapping techniques. ...
The stone tools and fossil bones from the earliest archaeological sites in Africa have been used over the past fifty years to create models that interpret how early hominins lived, foraged, behaved and communicated and how early and modern humans evolved. In this book, an international team of archaeologists and primatologists examines early Stone Age tools and bones and uses scientific methods to test alternative hypotheses that explain the archaeological record. By focusing on both lithics and faunal records, this volume presents the most holistic view to date of the archaeology of human origins.
