Abstract

[1]  Fusulinids of the Khan Formation of Eastern Iran are described. The assemblage includes 10 species of Pseudofusulina (two new species P. gachalensis and P. kalmardensis), 4 species of Eoparafusulina and single forms of Pseudoendothyra, Palaeostaffella (?) and Schubertella unidentifiable at species level. The assemblage is endemic. Similarity to the Kalaktash fusulinid association of Central Pamirs allows the assemblage to be referred to the Sakmarian. Similarity with assemblages of Central Pamirs, Karakorum, Eastern Hindukush, South Afghanistan, and Oman may evidence that the Posht Badam tectonic block where the section studied is located was a part of the South Tethyan biogeographic province in the Early Permian.
