Fig. 4 in The eoorthid brachiopod Apheoorthina in the Lower Ordovician of NW Argentina and the dispersal pathways along western Gondwana

Fig. 4. Early Ordovician palaeogeographic reconstruction showing inferred marine current pattern and possible dispersal routes between the Central Andean Basin, northern Africa, and European-Asian peri-Gondwanan terranes. Considering their position in the Ordovician maps, the names "East" and "West" Iapetus are proposed to replace the commonly used "North" and "South" Iapetus. ATA, Armorican Terrane Assemblage; CAB, Central Andean Basin. Palaeogeography based on Benedetto and Sánchez (1996), Astini (1998), Benedetto (2003), Fortey and Cocks (2003), Ramos (2009), Cocks and Torsvik (2013), and Torsvik and Cocks (2013a, b).
