SUPPLEMENTAL FIGURE CAPTIONS
SUPPLEMENTAL DATA 1—Columnar section of the Treptichnus pedum Zone of the Chapel
Island Formation in Fortune Head, Newfoundland. Stratigraphic height
measurements are shown in meters. Grain sizes are shown by the horizontal widths.
The color bars show the color of rocks (green=greenish gray; red=reddish gray).
The PC–C boundary at 15 m was defined by Brasier et al. (1994). The gutter cast
facies (GC facies) corresponds to the interval of 14–32 m, the siltstone dominated
facies (SiS-D facies) to 36–108 m, and the shoreline facies (Sh facies) to 108–
154m.
SUPPLEMENTAL DATA 2—Columnar section of the Rusophycus avalonensis Zone of the
Chapel Island Formation in Fortune Head, Newfoundland. The stratigraphic
heights, grain sizes and the color of the beds are shown as in the Supplementary
Data 1. The whole section is included in the sandstone dominated facies (SS-D
facies).
SUPPLEMENTAL DATA 3—Columnar section of the uppermost Dengying and Zhujiaqing
formations in Meishucun, Yunnan. Scale bar=5 m. The horizontal widths show
relief of the outcrop against weathering, not grain sizes.
SUPPLEMENTAL DATA 4—Columnar section of the Tsagaan Oloom and Bayan Gol formations
1
in Bayan Gol gorge, Gobi-Altai. Stratigraphic height measurements are shown in
meters. The horizontal widths show relief of the outcrop against weathering, not
grain sizes. The red line at 323 m corresponds to the boundary between the Tsagaan
Oloom and the Bayan Gol formations, namely the PC–C boundary in this study.
The stratigraphic heights between 323–334 m shows poor exposure. The unit 18
corresponds to 323–393 m, the unit 19 to 393–452 m, and the unit 20 to 452 m.
