Liaoningotitan

Liaoningotitan (meaning "Liaoning giant") is a genus of titanosauriform sauropod from the Early Cretaceous (Barremian) Yixian Formation in Liaoning, China. A redescription of the holotype proposed affinities of Liaoningotitan with the Euhelopodidae.

==Description== Liaoningotitan is a medium-sized sauropod, with an estimated body length of and shoulder height of based on comparisons with the closely related Euhelopus. Distinguishing features of Liaoningotitan include a ventral margin of the maxilla that is convex, an upper tooth row that is short and anteriorly positioned; an anterior extension of the jugal that nearly reaches the level of the anterior margin of the antorbital fenestra; a basally constricted quadrate wing of the pterygoid; imbricated upper teeth, with narrow spatulate crowns that are D-shaped in cross section, and no labial grooves or denticles; nine reduced and un-imbricated lower teeth; asymmetric lower tooth crowns which are elliptical-like in cross section, with lingual grooves and ridges and a lingually bulbous basal crown; a proximal expansion of the humerus that is about 54.9% the length of the humerus; and an ilium with a pointed preacetabular process.
