Abstract
Based on systematic study of the ichnofossils of the Upper Ordovician in west of Shahrud, 13 trace fossils, including: Comorhaphe cf Iobata, Spirophycus ichnosp., Neonerites uniserialis, Neonerites biserialis, Neonerites ichnosp., Didymaulichus ichnosp., Lorenzina cf kulczynski, Protopaleodictyon ichnosp., Helmintopsis ichnosp., Paleodictyon ichnosp., Phycodes palmatum, Palaeophycus cf. striatus, Palaeophycus sulcatus, Planolites ichnosp., Thalassinoides ichnosp., Socolicia ichnosp. have been recognized. These ichnofossils represent the nereites ichnofacies and indicate that the sediments formed in a relatively deep marine condition. The sedimentary structures and field observations confirm the data obtained from the ichnofossils.
