Gallimimus ("Fowl mimic"), is a genus of ornithomimosaurid dinosaur from the late Cretaceous period (Maastrichtian stage) Nemegt Formation of Mongolia. With a maximum length of around 4 metres (13 ft) and weighing as much as 440 kilograms (970 lb), it was one of the largest ornithomimosaurs. Gallimimus is known from multiple individuals, ranging from juvenile (about 0.5 metres tall at the hip) to adult (about 2 metres tall at the hip).

Gasosaurus was a tetanuran dinosaur discovered in Dashanpu, China. The scientific name, meaning "Gas Lizard", honours the gasoline company that found the Dashanpu fossil quarry in Sichuan Province, now named as the Lower Shaximiao Formation. It had strong legs but short arms, and based on its relationship to other dinosaurs, it was probably a carnivore. It measured between 3.5 and 4 metres in length and 1.3 m in height, with a weight of around 150kg, placing it in the midrange of carnivores by size. However, some estimates put its weight as high as 400kg, as very little is known about this dinosaur. It lived during the mid-Jurassic period (Bathonian and Callovian stages), around 164 million years ago.

Giganotosaurus ("Giant southern lizard") is a genus of carcharodontosaurid dinosaur that lived 93 to 89 million years ago during the Turonian stage of the Late Cretaceous Period. It is one of the largest known terrestrial carnivores, slightly larger than Tyrannosaurus, but smaller than Spinosaurus. Its fossils have been found in Argentina.

Gojirasaurus is a genus of dinosaur named after Gojira (the Japanese name for Godzilla). It was discovered in Revuelto Creek, Quay County, New Mexico. The type specimen is a partial skeleton of a subadult, about 5.5 m (18 ft) long, which can be extrapolated to a weight of approximately 150–200 kg (330–440 lb). An adult would have been around 6.5 m (21 ft) long. It lived during the Norian age of the Late Triassic Period, between 220 and 209 million years ago.

Guanlong ("Crown dragon") was a genus of tyrannosauroid dinosaur, one of the earliest known examples of the lineage. About 3.0 metres (9.8 ft) long, it lived 160 million years ago in the Oxfordian stage of the Late Jurassic period, 92 million years before its well-known relative Tyrannosaurus. This bipedal saurischian theropod shared many traits with its descendants, and also had some unusual ones, like a large crest on its head. Unlike later tyrannosaurs, Guanlong had three long fingers on its hands. Aside from its distinctive crest, it would have resembled its close relative Dilong, and like Dilong may have had a coat of primitive feathers.

Herrerasaurus ("Herrera's lizard," after the name of the rancher who discovered the first fossil of the animal) was one of the earliest dinosaurs. All known specimens of this carnivore have been discovered in northwest of Argentina, in late Triassic Period rocks (early Carnian stage, around 228 million years ago). Herrerasaurus was a lightly-built bipedal carnivore with a long tail and a relatively small head. Its length is estimated at 3 to 6 meters (10 to 20 ft), and its hip height at more than 1.1 meters (3.3 ft). It may have weighed around 210–350 kilograms (463–772 lb). In a large specimen at first thought to belong to a separate genus, Frenguellisaurus, the skull measured 56 centimeters (1.8 ft) in length.

Indosuchus raptorius is a genus of abelisaurid dinosaur from the Late Cretaceous Period (70 to 65 million years ago - the Maastrichtian era), a primitive theropod related to Abelisaurus. Like most theropods, Indosuchus was a bipedal carnivore. It was possibly 6 meters (20 ft) long, and had a crested skull, flattened on the top.

Ingenia ("One from Ingen Khoboor"), comes from several formations in the Upper Cretaceous of the Mesozoic, approximately 70 million years ago, and derives most prominently from the Bugin Tsav beds of the Nemegt Formation, which has also yielded the holotype of Mononykus olecranus. It is known from only a few specimens, which includes only the arms, legs, pelvis, shoulder girdle, and partial skull, and a few vertebrae. Material referred to "Ingenia" comes from older formations, but these are not well described.

Irritator is a genus of spinosaurid dinosaur that lived in the early Cretaceous Period (Albian stage), around 110 million years ago. Current estimations indicate a length of 8 meters (26 feet) and a height of 3 meters (9 feet). It was found in Brazil. Irritator was a theropod with an unusually shaped crest at the rear of its head, and probably ate fish.

Liliensternus was a genus of coelophysoid dinosaur from the Late Triassic period, between about 215-200 mya. Liliensternus was originally found in 1934 in Germany and was named after the German scientist, Dr. Hugo Rühle von Lilienstern. Liliensternus was approximately 5.15 m (17 ft) long, and may have weighed about 127 kg (280 lb). It might have preyed on herbivores like Plateosaurus.
