Where: Xinjiang, China (44.0° N, 87.3° E: paleocoordinates 42.7° N, 88.7° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Tugulu Group, Valanginian to Valanginian (139.8 - 100.5 Ma)

• "The geological data made available to Young were relatively scanty: the specimen, a fairly well preserved limb bone on a block of greyish sandstone, apparently came from the Changji River ("Changchiho"), and its age was determined as Early Cretaceous. The Cretaceous geology of northern Xinjiang has recently been reviewed by Shen & Mateer (1992). On the southern margin of the Junggar Basin, Cretaceous outcrops extend in a narrow zone along the northern edge of the Tian Shan fold belt. The Lower Cretaceous is represented there by the Tugulu Group, a thick succession of fluvio-lacustrine beds, which is divided into several formations (probably ranging in age from Neocomian to Albian; see Shen & Mateer, 1992). Although it is likely that the bone from Changji comes from the Tugulu Group, it is difficult to assign it to a particular formation on the basis of the available data."
