Gandititan is a basal titanosaurian sauropod dinosaur from the Late Cretaceous of what is now China. It was a long-necked herbivore, typical of sauropods, with a relatively short tail, a characteristic of titanosaurs compared to other sauropods. Titanosauria have a wide range of body sizes, and Gandititan falls around the middle, slightly on the smaller side. Discovered with a fairly well articluated spine from neck to tail, Gandititan is estimated at about 14 m in total body length.

Comparison of the holotype (BRSMG Cg3178, A and C right surangular, BAS specimen) and referred specimen (BRSMG Cg2488, B and D left surangular, Lilstock specimen) of Ichthyotitan severnensis gen. et sp. nov. To ease comparison, A and C have been reversed. A-B. Lateral view of both surangulars showing same unique shape; note the upturned, almost 90-degree angle bend and the spatulate-shaped posterior end. C-D. Medial view of both surangulars displaying same morphology posteriorly; anteriorly the Lilstock specimen (D) has been heavily eroded and distorted along its length. Note the position of an elongated foramen on the lateral surface (A-B), identified as part of the fossa surangularis that passes through the bone into the Meckelian canal. See also the damaged (?)angular that is articulated with the surangular and defined by a continuous groove (?suture) as seen in Fig 2H.
Original description: The diagram is based on strict consensus of five minimum-length trees using 13 ingroup taxa and 102 unordered characters (CI = 0.76; RI = 0.78) (Text S5). Scaled icons represent a diplodocid (Apatosaurus) [11], dicraeosaurid (Dicraeosaurus) [51], and a rebbachisaurid (Nigersaurus). Geographic distributions include Laurasian diplodocoids (western North America—Apatasaurus, Diplodocus, Suuwassea; Europe—Histriasaurus, Spanish rebbachisaurid) and Gondwanan diplodocoids (South America—Cathartesaura, Limaysaurus, Zapalasaurus; Africa—Rebbachisaurus, Nigersaurus). Temporal boundaries based on a recent timescale [52]. Color scheme: Laurasia (orange); Gondwana (blue); North America (solid orange); Europe (striped orange); South America (blue); Africa (striped blue).

Astigmasaura is a medium-sized rebbachisaurid sauropod dinosaur from the Late Cretaceous period of what is now Argentina. Rebbachisaurids had highly pneumatized bones that helped them to hold their weight on their four pillar-like legs, and extremely long tails. Astigmasaura was likely a ground-level browsing herbivore.

Rebbachisaurids are the latest known sauropod dinosaurs outside the titanosaur lineage. Cienciargentina is a rebbachisaurid from the Late Cretaceous, making it among the most recent. It had many hollow bones, and likely had batteries of teeth used for chewing, a rebbachisaurid feature unique among sauropods.
