Yunmenglong
''Yunmenglong'' is an extinct genus of somphospondylan sauropod known from the late Early Cretaceous of Henan Province, central China. Its remains were discovered in the Haoling Formation of the Ruyang Basin. The type species is ''Yunmenglong ruyangensis'', described in 2013 by Junchang Lü ''et al.'' on the basis of an incomplete postcranial skeleton. ''Yunmenglong'' shares some characters with ''Euhelopus'', ''Qiaowanlong'' and ''Erketu'', and a phylogenetic analysis places it as a sister taxon of ''Qiaowanlong'', both grouped with ''Erketu'' in a position more derived than ''Euhelopus'' but basal to Titanosauria. ''Yunmenglong'' represents the first long-necked sauropod dinosaur recorded from central China to date. ==References==
