Balochisaurus Balochisaurus (meaning "Balochi lizard", for the Baloch tribes of Pakistan) is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous of Pakistan. The type species is "B. malkani". The discovery was made (along with other dinosaur specimens) near Vitariki by a team of paleontologists from the Geological Survey of Pakistan. Formally described in 2006 by M.S. Malkani, the genus is based on seven tail vertebrae found in the Maastrichtian-age Vitakri Member of the Pab Formation, with additional vertebrae and a partial skull assigned to it. The author erected the family-level name Balochisauridae for "Balochisaurus", but it remains to be seen if this family will receive widespread acceptance.

Nqwebasaurus Nqwebasaurus (] with an initial postalveolar nasal click; anglicized as ) is the name given to a genus of dinosaur sometime between the Tithonian to Valanginian (Late Jurassic to Early Cretaceous). It was the basalmost ornithomimosaur. Its fossils were found in South Africa in the Kirkwood Formation, which is called Nqweba in the native language of the Xhosa. It was nicknamed "Kirky" after this formation before receiving its scientific name. "Nqwebasaurus" is the earliest known Coelurosauria specie from Gondwana, pre-dating other known North African taxa by 50 million years. It is also the first coelurosaur to be discovered and named from Africa.

Maxakalisaurus Maxakalisaurus is a genus of aeolosaurid dinosaur, found in Brazil, 45 km from the city of Prata, in the state of Minas Gerais in 1998. It was related to "Saltasaurus", a sauropod considered unusual because it had evolved apparently defensive traits, including bony plates on its skin and vertical plates along its spine; such osteoderms have also been found for "Maxakalisaurus". The genus name is derived from the tribe of the Maxakali; Topa is one of their divinities.

Albertosaurus Albertosaurus ( ; meaning "Alberta lizard") is a genus of tyrannosaurid theropod dinosaurs that lived in western North America during the Late Cretaceous Period, about 70 million years ago. The type species, "A. sarcophagus", was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named. Scientists disagree on the content of the genus, with some recognizing "Gorgosaurus libratus" as a second species.

Megalosauridae The defining megalosaurid is "Megalosaurus bucklandii", first named and described in 1824 by William Buckland after multiple finds in Stonesfield, Oxfordshire, UK. "Megalosaurus" was the first formally described dinosaur and was the basis for the establishment of the clade Dinosauria. It is also one of the largest known Middle Jurassic carnivorous dinosaurs, with the best-preserved femur at 805 mm and a proposed body mass of around 943 kg. Megalosauridae is recognized as a mainly European group of dinosaurs, based on fossils found in France and the UK. However, recent discoveries in Niger have led some to consider the range of the family. Megalosaurids appeared right before the split of the supercontinent Pangaea into Gondwana and Laurasia. These large theropods therefore may have dominated both halves of the world during the Jurassic.

Herrerasauridae Herrerasaurids are among the oldest known dinosaurs, appearing in the fossil record 231.4 million years ago (Late Triassic). These dinosaurs became extinct by the end of the Triassic period. Herrerasaurids were small-sized (not more than 4 m long) carnivorous basal saurischians. The best known representatives of this group are from South America (Brazil, Argentina), where they were first discovered in the 1960s. A nearly complete skeleton of "Herrerasaurus ischigulastensis" was discovered in the Ischigualasto Formation in San Juan, Argentina, in 1988. Less complete herrerasaurids have been found in North America, and they may have inhabited other continents as well.

Yaguarasaurus Yaguarasaurus is an extinct genus of mosasauroid from the Late Cretaceous (Turonian) period of Colombia, South America. The remains discovered (an articulated skull, some vertebrae and ribs) were defined as a new genus and species of mosasaurid, "Yaguarasaurus columbianus", by the Colombian paleontologist María Páramo, former director of the Museo de Geología José Royo y Gómez of INGEOMINAS in Bogotá. The first fossils remains of this animal suggested a cranial length of 47 cm and a total length of 5 m ; an additional skull that measures 87 cm long implies a larger size.

Cuyosuchus Cuyosuchus is an extinct genus of archosauriform reptile. Its fossils have been found in Late Triassic-aged rocks of the Cacheuta Formation, Mendoza, Argentina. "Cuyosuchus" is based on MCNAM 2669, a partial postcranial skeleton including 26 vertebrae from all parts of the spinal column, ribs, partial pectoral girdles, part of the pelvis, upper arms and part of the lower arms, the left thigh bone and shin, pitted armor scutes, and fragments. It was described in 1961 by Osvaldo Reig; the type species is "C. huenei". Although originally described as a proterosuchid, restudy by Julia Desojo and colleagues in 2003 found that it could not be assigned to any family.

Huabeisaurus Huabeisaurus ( , meaning "North China lizard") was a genus of dinosaur from the Late Cretaceous (Cenomanian to Campanian stages, around 99.7–70.6 million years ago). It was a sauropod which lived in what is present-day northern China. The type species, "Huabeisaurus allocotus", was first described by Pang Qiqing and Cheng Zhengwu in 2000. "Huabeisaurus" is known from numerous remains found in the 1990s, which include teeth, partial limbs and vertebrae. Due to its relative completeness, "Huabeisaurus" represents a significant taxon for understanding sauropod evolution in Asia. "Huabeisaurus" comes from Kangdailiang and Houyu, Zhaojiagou Town, Tianzhen County, Shanxi province, China. The holotype was found in the unnamed upper member of the Huiquanpu Formation, which is Late Cretaceous (?Cenomanian–?Campanian) in age based on ostracods, charophytes, and fission-track dating.

Carnotaurus Carnotaurus is a genus of large theropod dinosaur that lived in South America during the Late Cretaceous period, between about 72 and 69.9 million years ago. The only species is Carnotaurus sastrei. Known from a single well-preserved skeleton, it is one of the best-understood theropods from the Southern Hemisphere. The skeleton, found in 1984, was uncovered in the Chubut Province of Argentina from rocks of the La Colonia Formation. Derived from the Latin "carno [carnis]" ("flesh") and "taurus" ("bull"), the name "Carnotaurus" means "meat-eating bull", an allusion to the animal's bull-like horns. "Carnotaurus" is a derived member of the Abelisauridae, a group of large theropods that occupied the large predatorial niche in the southern Landmasses of Gondwana during the late Cretaceous. The phylogenetic relations of "Carnotaurus" are uncertain; it might have been closer to either "Majungasaurus" or "Aucasaurus".

Giganotosaurus Giganotosaurus ( ) is a genus of theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 99.6 to 97 million years ago. The holotype specimen was discovered in the Candeleros Formation of Patagonia in 1993, and is almost 70% complete. The animal was named G. carolinii in 1995; the genus name translates as "giant southern lizard" and the specific name honours the discoverer, Rubén D. Carolini. A dentary bone, a tooth and some tracks, discovered before the holotype, were later assigned to this animal. The genus attracted much interest and became part of a scientific debate about the maximum sizes of theropod dinosaurs.
