| 摘 要： | A new species of sauropod dinosaur Huanghetitan ruyangensis is erected based on the following characters： deepest body cavity with a dorsal rib reaching at least 2.93 m long, anterior caudal vertebrae with mushroom-shaped neural spines. Based on this new specimen of Huanghetitan found in the early Late Cretaceous Mangchuan Formation of Ruyang, Henan Province, the family Huanghetitanidae faro. nov. is proposed as a new rank to include only the genus Huanghetitan You et al. 2006. At present, Huanghetitan includes two species： H. liujiaxiaensis You et al., 2006 and H. ruyangensis sp. nov. The systematic relationships of Huanghetitan among sauropod dinosaurs are briefly discussed.

| Abstract: | A new species of sauropod dinosaur Huanghetitan ruyangensis is erected based on the following characters: deepest body cavity with a dorsal rib reaching at least 2.93 m long, anterior caudal vertebrae with mushroom-shaped neural spines. Based on this new specimen of Huanghetitan found in the early Late Cretaceous Mangchuan Formation of Ruyang, Henan Province, the family Huanghetitanidae fam. nov. is proposed as a new rank to include only the genus Huanghetitan You et al. 2006. At present, Huanghetitan includes two species: H. liujiaxiaensis You et al., 2006 and H, ruyangensis sp. nov. The systematic relationships of Huanghetitan among sauropod dinosaurs are briefly discussed. |
