Abstract

The alveolinid taxa, found in three stratigraphic sections of Eocene shallow-marine successions in the western Alborz -Baghdareh and Gheynarjeh sections- and eastern Iran -Chenesht section- regions, have been studied to determine their systematics and biostratigraphy for the first time. The rich alveolinid assemblages in these regions are correlated with coevalfaunas-inshallowbenthiczones-oftheTethyanprovince. The 29 species of alveolinids identified include: Glomalveolina lepidula,Alveolinaellipsoidalis,A.moussoulensis,A.subpyrenaica, A. aff.sakaraensis, A. tumida, A. decipiens, A. pisiformis,A.aragonensis,A.laxa,A.ilerdensis,A.rotundata,A. gr. guidonis, A. elliptica nuttalli, A. citrea, A. cf.citrea, A. cf. rugosa, A. cf.distefanoi, A. cf.montanarii, A. cremae, A. gr. cremae, A. cf.minuta, A. canavarii, A. oblonga, A. decastroi, A. aff.haymanensis, A. bayburtensis, A. frumentiformis, and A. aff.palermitana. On the basis of their distribution ranges, five Tethyan foraminiferal biozones have been recorded from themiddleIlerdianandCuisian-SBZ7–8andSBZ10–12-sedimentary successions. The data imply a close affinity between the studied area and other localities in the western Tethyan province.
