...T. Neagu Abstract The taxonomy and test morphology of Schackoina cenomana, S. cenomana gandolfi, and S. multispinata bicornis are reviewed on the basis of abundant material from Cenomanian (Cretaceous) localities of the eastern Carpathians in Romania. The particular features of the forms described...

... to a distinctly unstable planktonic foraminiferal structure, characterized by low species diversity and marked foraminiferal changes and events. Some of these took place at the same time (the rotaliporid crisis, the heterohelicid decline, the Hedbergella-Schackoina shift, the onset of the ‘large form eclipse...

... with a relative increase in abundance of Leupoldina (Selli) and Schackoina (Bonarelli). While the decrease in radiolarian diversity occurs within the black shale levels, the changes, either as turnover or fluctuation in abundance of calcareous nannoflora and, to a minor extent, of planktonic foraminifers, precede...
