dc.description.abstract
Study of a Cretaceous/Paleogene (K/Pg) boundary section in the Jagüel Formation, Neuquén Basin,Argentina, has revealed a new calcareous nannofossil species, Markalius neuquenesis sp. nov. This new species is medium to large in size (7.3 to 8.03 μm), with a broad, birefringent tube cycle divided into four sectors, each with at least one small perforation. The species is rare to few in abundance in the upper Maastrichtian through lower Danian Jagüel Formation and has also been observed in the Danian of the North Atlantic Ocean
