Huaxiazhoulong is a fairly large ankylosaurid dinosaur, at around 6 m in length. It was a robust quadruped with a beak and teeth adapted for processing its herbivorous diet. Huaxiazhoulong had an armor of osteoderms, and the characteristic ankylosaurid tail club which was likely used in defense against predators, as well as intraspecific combat.
Calvarius is a genus of styracosternan ornithopod from the Late Cretaceous of Spain. The name alludes to its chronostratigraphic proximity to the extinction event that wiped out the non-avian dinosaurs at the end of the Cretaceous. The highly modified metatarsal that is known from shows an example of convergent evolution, as it is more similar to non-iguanodontian ornithopods than to other styracosternans. It is thought that this is due to fulfilling a niche in its island habitat, resulting in Calvarius becoming a small-bodied animal, capable of rapid locomotion.

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.
Campananeyen is a rebbachisaurid sauropod that lived approximately 100 million years ago in the Late Cretaceous of what is now Argentina. Rebbachisaurids are the main group of diplodocoidea to have lived past the Jurassic, and had a more horizontal posture than contemporary sauropods, mainly the titanosaurs. They are unique among sauropods for having batteries of teeth used for chewing, rather than the typical peglike teeth sauropods used to strip leaves off branches.

Dzharacursor is an ornithomimid theropod dinosaur from the Late Cretaceous of what is now Uzbekistan. Ornithomimids like Dzharacursor are known for their long legs lending to a cursorial, or running, lifestyle. They had a feathered covering, and were likely omnivorous, or possibly herbivorous. Adult Dzharacursor could grow to approximately 3.5 m in length.

Ahvaytum is a saturnaliid sauropodomorph from the Late Triassic of what is now Wyoming. It is the oldest known dinosaur from the northern continent of Laurasia, challenging previous hypotheses of dinosaur origins and dispersal. Typical of basal dinosaurs from the Triassic, Ahvaytum was a small slender biped, reaching about 1 m in body length.

Huashanosaurus is a basal sauropod dinosaur that lived from the Early to Middle Jurassic periods of what is now China. It was a long-necked herbivore which still exhibited many basal traits of the earlier sauropodomorphs, while transitioning to obligate quardupedality. Huashanosaurus grew to approximately 12 m in length, and weighed around 10 t.
