Figure 1.

Triassic sequences and variations of sea level. Time scale after Ogg et al. (2016). Biozone cross-correlations are after Hardenbol et al. (1998). Sequence boundaries (sea-level fall events) are redesignated following a numbering scheme suggested by Hardenbol et al. (1998), however, the letter T is prefixed to each designation for convenience to make the numbers unique and not to confuse them with similar numbers in other periods. (Two events, in the Norian and Rhaetian [TNo2 and TRh1] are included provisionally, pending documentation of more widespread occurrence.)
