The occurrence of the genus Kelliella (Bivalvia, Kelliellidae) in shallow-water, Middle Miocene deposits of Poland
Barbara Studencka
Present-day representatives of the genus Kelliella are mostly confined to the abyssal zone (2000-6000 m), while paleontological data suggest shallower bathymetric requirements for their fossil congeners. The Late Eocene to Miocene records are from shallow-water (20-50 m) deposits; Pliocene and Pleistocene species come from deposits typical of bathyal zone (400-2000 m). New species Kelliella barbara sp. n. is described from the Badenian (Middle Miocene) shallow-water sands in the southern slopes of the Holy Cross Mts.
Key words: Bivalvia, Kelliellidae, bathymetric conditions, Badenian, Poland.
