Biostratigraphical study of vertebrate and Crustacean bearing horizons of Pabdeh Formation (Kuhrang area, Shahr-e-Kurd) Zagros basin, Southwest Iran

Abstract

Systematic investigation of vertebrate bearing horizons of Pabdeh Formation in Kuhrang area (Pole-Naal-Eshkanan, Kuhanak, Omid-Abad and Qanbar-Sini) leading to indentification of 8 families of Teleostis which includes: Fistularidae, Photichthyidae, Gempylidae, Myctophidae, Sternoptychidae, Gonostomatide, Clupeidae and Acanthuridae. Future to the fishes assemblages within the studied fauna 3 species of shrimp fossils were discriminated (Eopabdehus babaheydariensis, Eogordonella iranianiensis, Parsacus eocenicus). Based on the collected benthic and planctonic forminifers from the acid washing residues the Middle Eocene age can be assigned to the studied intervals.
