Where: Xizang, China (28.7° N, 85.8° E: paleocoordinates 52.5° S, 63.9° E)
• coordinate estimated from map
• small collection-level geographic resolution
When: Kangshare Formation, Changhsingian (254.2 - 252.2 Ma)
• Equivalent to Bed 17 in Shen et al. (2000). The contact between the Selong Group and the overlying Kangshare Formation is marked by the Caliche Bed, a thin layer of pedogenic calcrete which varies laterally in thickness. The Kangshare Formation is 7.0 m thick and is divided into three beds (Jin et al., 1996): Waagenites Bed, Otoceras Bed, and Ophiceras Bed. The Otoceras and Ophiceras Beds are Triassic in age.
• bed-level stratigraphic resolution
Environment/lithology: open shallow subtidal; lithified packstone
•JA: described by Shen et al. 2000 as a brown dolomitized crinoid packstone with brachiopods, corals, bryozoans, ostracods, foraminifers and calcareous sponges, above the "Caliche Bed", 0.07 m thick
Size class: macrofossils
