Middle Miocene (Badenian) chitons (Mollusca, Polyplacophora) from the Central Paratethys 3: additional data from Devecser (Bakony Mts, Hungary)

From the fossil-rich Middle Miocene sediments of Devecser, Tik-hegy only two Polyplacophora species have been identied so far (Ischnochiton rissoi (Payraudeau) and Cryptoplax weinlandi Šulc). In Tibor Berta’s private collection and a small material by the author, fossil remains of six additional chiton species have been distinguished (Leptochiton sulci Bałuk, Parachiton aicanus (Nierstrasz), Lepidochitona cf. lepida (Reuss), Rhyssoplax corallina (Risso), R. olivacea (Spengler), and Acanthochitona lacrimulifera Bałuk). e early Badenian chiton material of Devecser contains elements of the typical shallow-water Polyplacophora assemblages of the Central Paratethys. is is the rst record of L. sulci and A. lacrimulifera from Hungary. P. aicanus was also detected only recently for the rst time in Hungary from the nearby Várpalota locality. With 29 gures.
