A preventive archaeological operation carried out at Champ-Chalatras locality revealed evidences of a Middle Neolithique II occupation. They are located in two areas that revealed about 15 structures (hollow ones for the most), associated to ground levels. The study of ceramics showed a corpus widely marked by the meridional and oriental (southern and eastern) influences and allow to attribute the lot of containers of Champ-Chalatras to an elaborated phase of the Middle Neolithique. The data provided by the archeozoological study, from the vestiges gathered in several structures, show that most of the meat diet is based on a domestic origin. Most of the wild fauna is marginal and seems to come in complement to the former. The presence of cereal and milling devices associated with a diversified domestic fauna reveal new elements concerning the occupation mode of the banks of the Allier during the Middle Neolithique.
