| Abstract |
Twelve taxa, identified in Lower Eocene outcrop and borehole successions of the North Sea Basin and at Aktulagay in western Kazakhstan, are described here for the first time: Zygrhablithus bijugatus galeiformis subsp. nov., Ellipsolithus irregulariporus sp. nov., Ellipsolithus heilmannclausenii sp. nov., Pontosphaera megapachydisca sp. nov., Dictyococcites chriskingii sp. nov., Toweius brusselensis sp. nov., Blackites aktulagayensis sp. nov., Blackites rugosus sp. nov., Blackites thiedei sp. nov., Chiphragmalithus vandenberghei sp. nov., Lophodolithus mytiliformis sp. nov. and Nannoturba jolotteana sp. nov. In addition, one new taxonomic combination is proposed: Blackites dupuisii (STEURBAUT, 1991) new. com. Most of the new species have short stratigraphic ranges and, consequently, have great potential for high-resolution biostratigraphy and for refined dating of sedimentary sequences from middle to high latitudes of the northern hemisphere. |
