记述了产自河南汝阳地区晚白垩世早期莽川组一新的巨型蜥脚类恐龙--巨型汝阳龙(新属新种):Ruyangosaurus giganteus gen.et sp.nov..它具有以下特征:神经棘低,缺少椎前关节突隔板,神经弓的侧面具有大的、不规则的三角形凹,前关节横突隔板前后伸展,胫骨粗壮,达127 cm等.汝阳龙的发现显示在晚白垩世早期蜥脚类恐龙发生的分异程度要比以前想象的高得多.

The new gigantic sauropod dinosaur Ruyangosaurus giganteus gen. Et sp. Nov. From the early Late Cretaceous Mangchuan Formation of Ruyang, Henan, China is described. It is characterized by a lower neural spine, lack of centroprezygapophyseal lamina, a large, irregularly triangular deep fossa on the lateral surface of the neural arch, the prezygodiapophyseal lamina oriented anteroposteriorly, and a robust tibia, some 127cm in length. The discovery of Ruyangosaurus indicates that a higher diversity of sauropod dinosaurs occurred during the early Late Cretaceous than previously thought.
