Figure 2. Stratigraphy of the measured section at Mugher (Blue Nile Basin; figure 1c for the location of the section) marking the stratigraphic position of the crinoid sample (black arrow). Additionally, the black pentagon symbol marks the position of sample 2043b that has yielded upper Tithonian calcareous nannofossils (redrawn and modified after [21]). The depositional setting and inferred relative sea-level curve for the Mugher section is redrawn and slightly modified after Jain [20] and Jain &amp; Singh [21].
