Abstract: 

The Mila formation from late Early Cambrain to Early Ordovician age is well exposed in the Shahmirzad section consists of 5 lithological members. Several biozones of conodonts have been identified in this section, several taxa of body and trace fossils have been collected from members 2-5 of this section.
Member 1, consisting of stromotolitic dolomite, indicates at least one paleosol in the middle part. The second lithological member which includes several beds of salt peseudomorphs does not indicate any condont, while trilobites as well as trace fossils such as Rusophycus sp. and Cruziana sp. have been found frequently. These trace fossils, characteristic of cruziana ichnofacies, occur only in shallow marine environments. Eocrinoids debris and epirelief of the root of this fossil strongly supports this fact. In addition, presence of storm beds and oriented deposition of Hyolithids indicate high degree of water agitation in environment of deposition. Biozones of Conodont have been identified from members 3-5.
