... Hedbergella delrioensis shifted to a deep environment, and the deep-dwelling forms Rotalipora montsalvensis and Rotalipora reicheli first appeared. The primary paleoenvironmental cause of the observed changes in planktonic adaptive strategies is uncertain, yet their coincidence with an earliest Cenomanian...

.... globotruncanoides are not synonyms as is often stated in the literature, but two distinct species separated by their sizes, growth rates, chamber morphologies and position of the last-formed supplementary apertures. They both are important markers of the Cenomanian planktonic foraminiferal biostratigraphy ( Caron...

.... The first report of meridionally costellate forms from the late Albian-early Cenomanian was presented in Barr’s (1972) biostratigraphic study of Cretaceous planktonic foraminifera from Libya. Although no ornamentation pattern was mentioned in his original description of Hedbergella libyca ( Barr, 1972...
