Malefica is a hadrosaurid dinosaur from the Late Cretaceous of Texas in the United States. Like other hadrosaurs, Malefica was herbivorous, processing plant matter with their broad beaks and battery of teeth in the back of the mouth. It could grow to around 6 m in length, and weighed about 1 t. The discovery of Malefica helped to understand the distribution of hadrosaurs in Cretaceous North America, as well as evolutionary lineages between basal hadrosaurs and the more derived saurolophids.

Jiangxititan a titanosaurian sauropod from the Late Cretaceous of China. Typical for a sauropod, it had a long neck and stood on four pillar-like legs to support its massive body. Jiangxititan is a member of the Lognkosauria, which include some of the largest dinosaurs known, and is one of the few from mainland Asia. The discovery of Jiangxititan demonstrates the presence of both early-diverging and late-diverging titanosauriform sauropods in that area during the Late Cretaceous.

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.

This file represents a possible life appearance of the Indian Titanosaurian Sauropod dinosaur Jainosaurus septentrionalis from the Late Cretaceous (Maastrichtian) of India, belonging to the Lameta Formation.

Udelartitan is a titanosaurian sauropod from the Late Cretaceous of what is now Uruguay. It had the typical sauropod body plan, standing on four thick pillar-like legs, and possessing a long neck. Titanosaurs are a very diverse group, Udelartitan was a small one, estimated at only 15 m in body length. Though a skull has yet to be discovered, it probably had peglike teeth, and a large gut for processing vegetation.
