| Abstract: | The first data on the taxonomic composition and stratigraphic range of the late Campanian planktonic foraminifers encountered
in the middle and upper parts of the Moni Formation, southern Cyprus, are reported. Finds of planktonic foraminifers are associated
with the bentonitic clay that composes the matrix of the Moni Formation. The planktonic foraminiferal assemblages revealed
are very similar to those from the Kannaviou Formation, western Cyprus, but they are more diverse and yield several key species
missing in the Kannaviou sediments. The planktonic foraminiferal assemblages discussed are referred to the Globotruncana aegyptiaca Zone and to the lowermost Gansserina gansseri Zone of the upper upper Campanian of the standard scale. The intraregional correlation of the Moni sections, depth of erosion
of the upper part of the formation, and its relationship with the Kannaviou Formation have been refined. When subdividing
the upper Campanian sediments based on planktonic foraminifers it is suggested that additional datum planes are used, such
as the FADs of Globotruncanella citae and Trinitella scotti. For tracing the Campanian-Maastrichtian boundary (GSSP), attention should be paid to the LADs of Globotruncana bulloides and Contusotruncana fornicata and the potential use of Globotruncanita (Elevatotruncana) eolita sp. nov. should be assessed. It is shown that subfamily Archaeoglobigerininae Salaj, 1987, emend. O. Korchagin is the older
synonym of subfamily Archaeoglobigerininae Georgescu, 2005. Two poorly known and three new planktonic foraminiferal species
are described. |
