Fig. 4 in Ordovician ostracods from east central Iran

Fig. 4. Palaeogeographical position of Iran during the late Middle Ordovician. The ostracod fauna of the Shirgesht Formation (species of Cerninella and Aechmina?) appears to show affinity with that of the late Middle Ordovician of Spain and western France (Ibero−Armorica), the position of which is arrowed in the figure, and which also lay in a peri−Gondwanan setting. A second arrow points to the palaeogeographical position of Podolia.
