Fig. 2 in Brachiopods from the uppermost Lower Ordovician of Peru and their palaeogeographical significance

Fig. 2. Stratigraphic scheme of the lower part of the San José Formation at the Carcel Puncco Canyon (Inambari River), showing the position of the fossiliferous horizons yielding the studied brachiopods. The open circle indicates probable occurrence. Black star indicates the occurrence of late Floian (Early Ordovician) conodonts belonging to the upper part of the Oepikodus evae Biozone (Sarmiento et al. 2001; Gutiérrez−Marco et al. 2004).
