Also known as Qijianglong guokr type locality

Where: Chongqing, China (29.0° N, 106.6° E: paleocoordinates 28.0° N, 110.7° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Suining Formation, Late/Upper Jurassic (161.5 - 145.0 Ma)

• Wang et al. (2019) provide detrital zircon U/Pb mean ages of 114.4±1.1 Ma for the middle Suining Formation in Sichuan Basin, but it's not entirely certain whether this revised age is applicable to this collection

• formation-level stratigraphic resolution

Environment/lithology: terrestrial; calcareous mudstone and gray, green sandstone

Size class: macrofossils

Collection methods: As a lead to the elusive vertebrate fossils from the Suining Formation, a local farmer (Cai Changming) discovered sauropod vertebrae in his backyard in Heba Village, Beidu Township, in

•the early 1990s. In 2006, construction workers working 500 m from the original locality spotted a 0.7 m long neopterygian fish (Lepidotes). These discoveries prompted Qijiang District to commission a survey of the area by the Fossil Research and Development Center of the Third Geology and Mineral Resources Exploration Academy of Gansu Province.
