Fig. 8 in Brachiopods from the uppermost Lower Ordovician of Peru and their palaeogeographical significance

Fig. 8. Palaeogeographical reconstruction of the southern hemisphere for the Early−Mid Ordovician transition, based on Terra Mobilis (Scotese and Denham 1988), with the distribution of the studied brachiopod genera. Dark grey area indicates distribution of Ahtiella during Arenig times; light grey area indicates regions invaded by Ahtiella during Llanvirn times.
