ammonites
Tianjialing (Permian of China)

Where: Shanxi, China (37.4° N, 110.9° E: paleocoordinates 29.8° N, 89.6° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Shihtienfeng (Shiqianfeng) Formation, Wuchiapingian (259.0 - 254.0 Ma)

• "lower part of Shihtienfeng Formation, Upper Permian" (Gao, 1989 pp. 1234, 1238);

•" [...] the lower part of the Shihtienfeng Formation can be correlated with the Cis[t]ecephalus Zone of South Africa" (Gao, 1989 p. 1239);

•The Cistecephalus Assemblage Zone is Wuchiapingian, according to Catuneanu et al. (2005, J. African Earth Sci. 43)

•Additional note: The name "Shihtienfeng" appears to be identical to "Shiqianfeng", often used in non-paleontological literature for the Upper Permian red beds of the Ordos Basin succession (TL).

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial; lenticular, fine-grained, red conglomerate and red mudstone

• "All of the fossils were collected from a lens of fine, gray-purple conglomerate in purple mudstone" (Gao, 1989)

Size class: macrofossils

Collected in 1978-1979; reposited in the IVPP
