1860, attribution on the plate. Palaeolithic and mesolithic tools imagined hafted in wooden shafts. In the case of the paleolithic tools this is almost certainly incorrect. Boucher De Perthes was a pioneer in Antediluvian (palaeolithic) studies, claiming coexistence of men with mammoths in a long period of human antiquity (\Antiquites Celtiques et Antidiluviennes\" 1849). Some of De Perthes' extravagant conjectures may have deterred acceptance by the wider scientific community. His poor drawings of human tools (as here) always left doubt that they might be natural rather than man made. It was not until the visit of Falconer, Evans and Prestwich to De Perthes' Abbeville sites in 1858/1859 that general acceptance for human antiquity began. Later, these same authors saved science from a fake human fossil (the Moulin Quignon jaw 1863) which Boucher de Perthes had uncritically accepted."
