|---|---|---|---|---|
| 0.323 ± 0.003 | 0.318 / 0.328 | 7 | mudrock below the base of the carbon isotope excursion, initial ratio Mean and standard deviation recalculated from 7 analyses, 0.318 to 0.328 (708 0.325; 709 0.328; 710 0.322; 711 0.323; 712 0.326; 713 0.321; 713 (2) 0.318). Negative depths of the table, below the base of the carbon isotope excursion. Six levels below the base of the excursion, 0.318 to 0.328, consistent with the text (about 0.32). | Dickson et al.

| 0.346 ± 0.023 | 0.299 / 0.375 | 23 | mudrock from the base of the carbon isotope excursion upwards, initial ratio Mean and standard deviation recalculated from 23 analyses, 0.299 to 0.375 (A1a 0.358; A1d (dark lam.) 0.348; A1 1.5-3cm (upper) 0.309; A1 1.5-3cm (upper) (2) 0.338; A1 4-6cm (bottom) 0.341; A1 4-6cm (bottom) (2) 0.328; A1 6-6.5cm 0.357; A1 8-9cm 0.365; A1 8-9cm (2) 0.360; B2 base 0.360; C1 0.371; D2 base 0.366; D4 top 0.368; E4 top (top) 0.358; 715 0.375; 716 0.350; 717 0.360; 719 0.352; 720 0.350; 722a 0.346; 720' 0.307; 727 0.299; 730 0.299). Brief drop to 0.31-0.34 in lamina A1 (0.02-0.04 m), then 0.35-0.375 and 0.30 at the top. The text gives a maximum of 0.38-0.39 during the PETM; Table S3 peaks at 0.375 (715). Name 720 is used twice (1.48 and 2.23 m): the second is written 720'. PETM isochron at 0.359 ± 0.007 (55.0 ± 1.6 Ma, MSWD 5), all data at 0.345 ± 0.011 (55.9 ± 2.4 Ma, MSWD 50). | Dickson et al.
