Fig. 2

Stratigraphic column, fossil occurrences, and geochemical data (δ13C, δ238U, and Ce/Ce*) for our composite Olenek Uplift section. δ13C data are from ref. 99. Paleontology is described in detail in ref. 34. Modern Bahamas median δ238U value is from ref. 55 and oxic/anoxic Ce/Ce* cutoff value of 0.9 is from ref. 21. Note that the U-Pb zircon age of 543.9 ± 0.24 Ma published by ref. 30 from the Syhargalakh Formation was reinterpreted as 542.8 ± 1.3 Ma using the most concordant grains by ref. 103.
