Xi Ujimqin Qi, Section 12, Bed 5, Sample P12H1 (Permian of China)

Where: Nei Mongol, China (44.3° N, 117.7° E: paleocoordinates 34.0° N, 99.3° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Xiujimqinqi Formation, Wordian (266.9 - 264.3 Ma)

• Formerly Houtoumiao Formation. Thought to be correlative with the Zhesi Formation (=Jisu Honguer Formation), which is constrained to the Wordian because of the presence of the fusulinid Monodiexodina sutchanica zone (early Midian, or Wordian, in Primorye) (Shi et al., 2002) and smooth examples of the Wordian index conodont Jinogondolella serrata (Wang et al., 2004).

• group of beds-level stratigraphic resolution

Environment/lithology: lithified, shelly/skeletal, gray sandstone

Size class: macrofossils
