Eopinacosaurus is an ankylosaurid dinosaur that was originally assigned to Pinacosaurus, until a 2026 analysis reassigned it as a distinct genus. Like all ankylosaurs, it was a heavily armored quadrupedal herbivore. Notable defensive adaptations include the characteristic tail club, as well as sizable horns protruding backward from the head.

Norellraptor is a microraptorian dinosaur known from a specimen with exceptionally well-preserved feathers. Its discovery supports evidence that gliding and flight-related traits evolved independently in multiple dinosaur groups. Norellraptor had long feathers on its arms and legs, typical of microraptorians, resulting in a four-winged body plan.

Kayrasaurus is a therizinosaurian dinosaur that lived during the Early Cretaceous period in what is now China. At an estimated 3.6 m in total body length, it is the largest therizinosaur known from the Jehol Biota. Like other therizinosaurs, Kayrasaurus was a bipedal herbivore with large curved claws on each hand.

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.
