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
