Also known as Gucheng (He-Shan-Kou Formation); Ordos Basin
Where: Shaanxi, China (39.5° N, 111.0° E: paleocoordinates 39.8° N, 89.2° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Heshanggou Formation, Olenekian to Olenekian (251.2 - 242.0 Ma)
• Original formation name spelling >>He-Shang-Gou<< is replaced by the much more common spelling >>Heshanggou<<. (TL)
•"Lower assemblage" of the Heshanggou Formation of the Ordos Basin, the age of which is based entirely upon biostratigraphy (see Nesbitt et al. 2011, Earth Env. Sci. Trans. Roy. Soc. Edinburgh). Vertebrate biostratigraphy (presence of the Anisian taxon Kannemeyeria in the overlying "upper assemblage" of the Heshanggou and presence of the Early Triassic Proterosuchus in the "lower assemblage") as well as plant and microspore data suggests an Olenekian-earliest Anisian age (Nesbitt et al. 2011, Earth Env. Sci. Trans. Roy. Soc. Edinburgh)
• bed-level stratigraphic resolution
Environment/lithology: terrestrial; lithified, red sandstone
Size class: macrofossils
Reposited in the IVPP
Collection methods: surface (float), mechanical,
• Li (1983) says that Gucheng locality yielded 16 specimens but lists a total of 17 (see catalogue numbers in taxonomic list). (TL)
