Another Chinese dinosaur I missed, officially out in June. The name appeared with informal status in a number of news stories in German and Chinese a few months back. Now it's validly published. The pdf is free.

A nearly complete sauropod skeleton, collected from the Jehol Biota of western Liaoning, is described briefly as a new titanosauriformes, Liaoningotitan sinesis gen. et sp. nov. Its diagnostic characters include:ventral margin of maxilla is convex, upper tooth row is short and anteriorly positioned; anterior extension of jugal nearly reaches the level of the anterior margin of the antorbital fenestra; quadrate wing of the pterygoid constricted basally; upper teeth are imbricated, narrow spatulate crown is D-shaped in cross section, with labial grooves and denticles absent; well reduced and un-imbricated nine lower teeth; lower tooth crown is asymmetric, elliptical-like in cross section, lingual grooves and ridge present, basal crown bulbous lingually; proximal expansion of the humerus is about 54.9% the length of the humerus, ilium with a pointed preacetabular process. Preliminary result of the phylogenetic analysis shows that Liaoningotitan falls into the clade of titanosauriformes, and is more derived than Euhelopus and Brachiosaurus.
