Abstract: The isolated valves of Polyplacophora species are rare elements of the Hungarian Miocene fossil assemblages. This paper provides description of a rich and well-preserved chiton fauna from Bánd and Devecser (Bakony Mts) collected by two amateur collectors. Eight species of six genera were identified in this Early Badenian (Middle Miocene) fauna: Lepidopleurus (Lepidopleurus) cajetanus, Lepidochitona sp., Ischnochiton rissoi, Chiton corallinus, Chiton (Rhyssoplax) olivaceus, Acanthochitona faluniensis, Cryptoplax weinlandi, Cryptoplax margitae. Up to now, this is the most diverse Polyplacophora assemblage known from the Hungarian Miocene (and also Cenozoic) formations. Four of the eight species were recognized for the first time from Hungary: L. cajetanus, I. rissoi, C. corallinus and C. olivaceus. The widespread Central Paratethyan species, C. weinlandi is represented by particularly rich and variable material, rendering the study of ontogenetic changes. The taxonomic composition of this chiton material corresponds well to the other Polyplacophora faunas known from the Central Paratethys (e.g. Poland, Austria, Romania).
