Precise taxon.my an. the chron.stratigraphic calibration.of the Middle Eocen. Alveolin. from Cen.ral Iran.is here un.ertaken.from the Chah-Talkh section.of the southern.Sabzevar region.Cen.ral Iran.. We have iden.ified Alveolin. kieli, Alveolin. stercusmuris an. Alveolin. n.ttalli alon. with the n.w species Alveolin. ozcan. n. sp. that we in.lude in.o the Alveolin. elliptica group. We have also foun. n.mmulites uron.en.is, n.mmulites obesus an. n.mmulites cf. vern.uili an. associated calcareous n.n.ofossils that look reliable to make thoughtful correlation. with the Shallow Ben.hic Zon.s(SBZ). The foramin.feral biostratigraphy suggests an.assign.en. to the upper part of the lower Lutetian.lower part of the middle Lutetian.SBZ13(Middle Eocen.), further stren.then.d through the iden.ification.of the calcareous n.n.ofossil n.14b-n.15b or Cn.8-Cn.10 biozon.s, providin. a solid correlation.with the global stratigraphic stan.ards.
