Reason for describing collection: | taxonomic analysis |
Collection method comments: 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. |
