Geography
Country: | China | State/province: | Nei Mongol | County: | Zhuengeerqi |
Coordinates: | 39.7° North, 111.0° East (view map) | ||||

Stratigraphy
Formation: | Heshanggou | ||||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: 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) |

Preservation of anatomical detail: | good |
Articulated whole bodies: | none |
Associated major elements: | some |
Disassociated major elements: | some |
Disassociated minor elements: | none |

Collection methods and comments
Collection methods: | surface (float),mechanical,field collection |
Reason for describing collection: | taxonomic analysis |
Museum repositories: | IVPP |
Collection method comments: The holotype specimen from this locality (He-Shang-Gou Formation) is in good condition- A second specimen is noted from "the Er-Ma-Ying Formation at Zhungeerqi, Inner Mongloia". 16 additional individuals of the same taxon collected from the nearby (17.5 km) Gucheng locality are "in rather poor condition." |
