...et celui de Nopcsaspondylus
Holotype (lost), represented by a complete mid to posterior dorsal vertebra,with centrumand neural arch separated. The small centrum and large pleurocoel suggest that they derive from the same vertebra, as this is a common feature in rebbachisauroids.
Diagnosis: diplodocoid sauropod characterized by mid to posterior dorsal vertebrae with very reduced centra, forked medial centropostzygapophyseal lamina, lateral lamina of the neural spine formed by the spinodiapophyseal lamina plus a lateral spinopostzygapophyseal (different from that forming the postspinal lamina).

Two new described diplodocids from Argentina, Amargatitanis macni and Nopcsaspondylus alarconensis
Abstract: A study of the abundant and undescribed isolated and associated bones and teeth from the La Amarga Formation (Barremian of Neuquén, Argentina ) permitted the recognition of additional clades of sauropod dinosaurs: basal titanosauriforms, both basal and derived titanosaurs, and rebbachisauroid diplodocoids, which are now added to the already known dicraeosaurids and a recently published basal diplodocoid. These forms substantially increase the knowledge on the Early Cretaceous sauropod diversity in Gondwana.

- Zhuchengosaurus maximus (Zhao et al)
Celui-là doit être un Hadrosaure de plus de 16 mètres de long !
- Amargatitanis macni (Apesteguia)
Un Titanosaure argentin.
- Nopcsaspondylus alarconensis (Apesteguia)
Un Diplodocoïde argentin, nommé à partir d'une vertèbre perdue.
- Jiangjunosaurus junggarensis (Jia et al)
Un Stegosaure chinois.
- Zhejiangosaurus lishuiensis (Lu et al) et Zhongyuansaurus luoyangensis (Xu et al)
Ces deux là sont des Nodosauridés de Chine.
