Feuilles ou fumiers ? Observations sur le rôle des poussières sphérolitiques dans l'interprétation des dépôts archéologiques holocènes

The detailed study of morphological and mineralogical properties of ligneous angiosperm leaf calcium oxalate crystals and of calcitic spherulites produced by small ruminants allows us to reconsider the existence of Neolithic leaf-foddering. Although clearly documented in waterlogged sites, no proof of this practice has been recovered to date from Mediterranean dry sites.
