Abstract
The late Badenian (early Serravallian) conoideans from the Pidhirtsi Beds of western Ukraine (central Paratethys) have been investigated by means of a comprehensive and easy-to-perform morphometric approach, allowing the characterisation of eleven species, of which seven are new to science: Mangelia angulicosta sp. nov., M. larga sp. nov., M. pseudorugulosa sp. nov., M. odovychenae sp. nov., Bela varovtsiana sp. nov., Bela? robusta sp. nov., Pyrgocythara turrispiralata sp. nov. Additionally we also identified Raphitoma cf. R. ringicula, Andonia sp. aff. A. transsylvanica, Teretia cf. T. turritelloides, and Haedropleura sp. aff. H. septangularis. The relative high number of new species documented, relative to the total previously known from this stratigraphic interval, is interpreted as resulting mainly from combined methodological (dearth of taxonomic studies on Ukrainian conoideans) and environmental (high degree of habitat fragmentation in reef setting) factors. The conoideans documented herein add impo...
Highlights
The relative high number of new species documented, relative to the total previously known from this stratigraphic interval, is interpreted as resulting mainly from combined methodological and environmental factors
The lack of typical warm-water indicators (e.g., Conidae, Clavatulidae, or Pseudomelatomidae) within the studied material supports the interpretation that the fauna thrived during the late phase and/or soon after the Middle Miocene Climatic Transition (14.2−13.8 Ma)
