Global sea level and continental groundwater dynamics during the Early Triassic. Time scale and magnetostratigraphy are from ref.13,14. a GR series at Daxiakou (black) and Chaohu (blue) are from ref.13. cpm: counts per minute. b, c DYNOT and ρ₁ models of the GR series at Daxiakou. d, e DYNOT and ρ₁ models of the GR series at Chaohu. The DYNOT and ρ₁ models were estimated using a running window of 400 kyr (see Supplementary Tab. 1 for sample rates for each spectrum). Confidence levels were estimated by a Monte Carlo analysis with 5000 iterations. f, g Sequence and sea-level variations of the European Tethys^7,9 (*Supplementary Note 2 and Supplementary Fig. 13 for details). h–j Lithology, magnetostratigraphy, sequences in the continental Germanic Basin^13,40 (Fig. 5 for details). k Spores and pollen diversity in Pakistan⁴⁷. l Earth’s obliquity forcing intensity of La2004¹⁹, La2010d⁴⁹ and in South China³¹
