Fig. 1 in First report on the occurrence of Neseuretinus and Ovalocephalus trilobites in the Middle Ordovician of Iran

Fig. 1. Geographical map (A) showing the position of fossil locality in the Derenjal Mountains north of Tabas and stratigraphical column (B) through Section B in the upper part of the Shirgesht Formation, showing stratigraphical ranges of selected trilobite, ostracod, and conodont species (after Ghobadi Pour et al. 2006).
