“…The dominant species in the P4a Subzone are Morozovella acuta , M. aequa , M. velascoensis , M. lacerti , Acarinina mckannai , Subbotina velascoensis , S. compressaformis , and Parasubbotina variospira . Traditionally, the LO of G. pseudomenardii is approximately simultaneous within upper most part of the calcareous nannofossil Zone NP5 (e.g., Baceta, Pujalte, Serra‐Kiel, Robador, & Orue‐ Etxebarria, ; Berggren & Pearson, ; Dinarès‐Turell, Baceta, Bernaola, Orue‐Etxebarria, & Pujalte, ; Schmitz et al, ). On the other hand, Farouk and Faris () noted that small specimens (<125 μm) of G. pseudomenardii have been found within the topmost part of calcareous nannofossil Zone NP4 (NTp8B) slightly above the LO of Morozovella velascoensis , which is confirmed in the present study (Figures , and ).…”
