Huakedaliang, Dayu township, Jiyuan City (Permian of China)

Also known as Locality 63024

Where: Henan, China (34.9° N, 112.4° E: paleocoordinates 27.9° N, 89.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Shangshihezi Formation, Wuchiapingian (259.9 - 254.2 Ma)

• Shangshihezi Formation; also referred to as the upper portion of Upper Shihhotse Formation. Correlated to the Cistecephalus Assemblage Zone of South Africa, which is Wuchiapingian in age

•"The Jiyuan fauna, with Honania and Tsiyuania, comes from the Upper Shihezhi (formerly Shihhotse) Formation, of Henan Province in northern China (Fig. 2), which dates from upper Roadian to mid Wuchiapingian, based on palynology (F. Liu et al., 2015) and magnetostratigraphy (Embleton et al., 1996; Stevens et al., 2011). The Jiyuan Fauna is from near the top of the unit, and is dated as late Wuchiapingian (J. Liu et al., 2014) or early Wuchiapingian (F. Liu et al., 2015)." (Benton 2016)

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; fine-grained sandstone and concretionary mudstone

• Most known fossils from this locality originate from a thin layer (layer 23), which is dark purple pebbly fine sandstone; although some teeth are also collected from layers 22 and 24, which are dark purple mudstone with calcareous concretion

Size class: macrofossils
