NEW DATA ON THE RANGES OF SOME CRETACEOUS TETHYAN RADIOLARIA

In a recent study of Mesozoic sediments in Cyprus rich and diverse ass emblages of, usually, well-preserved radiolarian specimens were examin ed. Of 141 species recognized only 75 have been previously formally de scribed. The ages of the radiolarian assemblages recovered from the Ka nnaviou Formation have been calibrated by the use of co-occurring calc areous nannofossils and planktonic foraminifera and are considered to be Campanian in age. Of the 75 formally named species recognized, 12 s pecies have not been previously recorded from Campanian sediments. The se species are not considered to be reworked due to their preservation al state, their abundances, and their occurrence patterns within the s amples and sections analysed.
