New pareorine gastropod species from the Danian (Paleocene) of the Haymana-Polatli Basin, Central Turkey

2022    Hosgor, Izzet; Pacaud, Jean-Michel

Lower Paleocene gastropod macrofaunas of Turkey (Anatolia) are seldom collected and studied due to their poor preservation. Two new pareorine gastropod species are described from the Caldag Formation of the Haymana-Polatli Basin in Central Turkey. Sigmesalia erifensis n. sp. and Sigmesalia anatole n. sp. were found in foraminiferal wacke-to-packstones associated with algal limestones in the Erif section. The analysis of benthic foraminifers and dasycladaceans suggests that the Caldag Formation was deposited in tropical conditions, probably within the photic zone. These newly identified pareorine species record the first abundant macrofossil gastropod assemblage found in the Danian sediments of the Erif section.
