根据内蒙古中侏罗统海方沟组的前翅，建立了一新种（Hsiufua chaozhang et Wang），归属于蛇目，等蛇目，蛇目，Campterophlebiidae。它是中国已知的最大的瀑布，也是世界上第四大瀑布。二叠纪齿龙的最大尺寸（基于前翼长度）小于中生代，这可能是由于二叠纪齿龙和原齿龙之间对猎物的竞争。侏罗纪齿形动物的最大体型比它们现存的近亲大的原因很可能是来自当代空中脊椎动物的竞争更少，捕食压力更小。
A new genus and species,Hsiufua chaoiZhang et Wang, is established based on a forewing from the Middle Jurassic Haifanggou Formation in Inner Mongolia, China and attributed to Campterophlebiidae, Isophlebioidea, Odonata. It is the largest odonate known in China and the fourth in the world in terms of forewing length. The maximum size (based on forewing length) of Odonata is smaller in the Permian than in the Mesozoic which is probably due to competition for prey between Odonata and Protodonata in the Permian. The reason that the maximum size of Jurassic odonates is larger than that of their extant relatives is most probably less competition and lower predation pressure from contemporary aerial vertebrates.
