| - This study describes the chiton fauna (Mollusca, Polyplacophora) from deposits of the Oligocene to Miocene marine sequence of Aquitaine Basin (southwestern France) and of late Miocene of Ligerian Basin (western France). This first part of the work describes the chitons belonging to six families: Leptochitonidae, Hanleyidae, Ischnochitonidae, Chitonidae, Schizochitonidae and establishes the new family Spinochitonidae. The studied fossils consist of 367 disarticulated valves from many sites in the Aquitanian Basin and one (Moulin Pochas) in the Ligerian Basin. We identified 19 species, 13 of which were already known, and six are described as new: Leptochiton aturriensis n. sp., Parachiton palmorum n. sp., Ischnochiton renardi n. sp., Connexochiton vivesi n. sp., Lucilina saubadeae n. sp., and Schizochiton tasteti n. sp. Spinochitonidae new fam. and Spinochiton new gen. are described. Ischnochiton abbessi n. comb. and Spinochiton gaasi n. comb. were transferred from the original genus Chaetopleura based on the new material studied. Some records of previously described species are particularly noteworthy: Hanleya glimmerodensis, previously known from the late Oligocene of Germany, is reported for the first time for the middle Oligocene of the Aquitaine Basin; the stratigraphic distribution of Lepidopleurus benoisti, Leptochiton josei, Ischnochiton rissoi, I. korytnicensis, Ischnochiton abbessi, Chiton corallinus and C. assurrectum is extended. A complete discussion on the chiton fauna from the Aquitaine and Ligerian Basins, consisting of all the species, in the six families from the present study and additional material, will be given in the second part of this work.
