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. |
