FIGURE 3. First appearance (FAD) (blue triangles) and last appearance (LAD) datums (red triangles) for indicator planktic species identified in this study to constrain the age of the assemblage from the olive-green mud unit from the northern Namibian continental shelf. The ages were based on studies from Wade et al. (2011) and Spezzaferri et al. (2018b), and confirmed in Kennett & Srinivasan (1983) and BouDagher-Fadel (2015). The blue rectangle represents the ages obtained from strontium isotopes (Compton and Bergh, 2016). The gray horizontal bar represents the age obtained from the indicator species in this study that coincides with the Sr-isotope data.
