| The species of the European turrid genus Spirotropis are reviewed and the possible pathways of the evolution and spreading of the genus during the Neogene are outlined. Nine species are recognised: S. spinescens (Bellardi), S. badensis sp. nov. (Middle Miocene, Paratethys), S. karamanensis sp. nov. (Middle Miocene, Turkey), S. tortonica sp. nov. (Late Miocene, Mediterranean Basin), S. gramensis sp. nov. (Late Miocene, North Sea Basin), S. modiolus (de Cristofori & Jan) (Early Pliocene, Mediterranean Basin), S. confusa (Seguenza) (Pliocene to Recent, North Sea Basin to Mediterranean Basin), S. monterosatoi (Locard) (Recent, Morocco to Iberian Basin), and S. azorica Bouchet & Warén (Recent, Azores). The ancestral form is Spirotropis (s.lat.)... |
