Carcharodontosaurus was a gigantic carnivorous carcharodonto- saurid dinosaur that lived around 98 to 93 million years ago, during the Cretaceous Period. Carcharodontosaurus was a carnivore, with enormous jaws and long, serrated teeth up to eight inches long. Paleontologists once thought that Carcharodontosaurus had the longest skull of any of the theropod dinosaurs.

Carnotaurus ("Meat-bull", referring to its distinct bull-like horns was a large predatory dinosaur, with horns vaguely resembling a bull's. Only one species, Carnotaurus sastrei has been described so far. Carnotaurus lived in Patagonia, Argentina during the Maastrichtian stage of the Late Cretaceous, and was discovered by José F. Bonaparte, who has uncovered many other South American dinosaurs. Carnotaurus was a medium-sized theropod, about 9.0 m (30 ft) in length, 3 m tall at the hips, and weighing about 1,600 kg (1.76 tons). The most distinctive features of Carnotaurus are the two thick horns above the eyes, and the extremely reduced forelimbs with four fingers. It is also characterized by its unusually long neck (compared to other theropods), and its small head with box-shaped jaws. It had a small skull, a thick chest, and a thin tail. The eyes of Carnotaurus faced forward, which is unusual in a dinosaur, and may indicate binocular vision and depth perception.

Caudipteryx ("Tail feather") is a genus of peacock-sized theropod dinosaurs that lived in the Barremian age of the early Cretaceous Period (about 127 million years ago). They were feathered and remarkably birdlike in their overall appearance. Caudipteryx, like many other maniraptorans, has an interesting mix of reptile- and bird-like anatomical features. Caudipteryx had a short, boxy skull with a beak-like snout that retained only a few tapered teeth in the front of the upper jaw. It had a stout trunk, long legs and was probably a swift runner. On the hands it had symmetrical, pennaceous, feathers that had vanes and barbs, and that measured between 15–20 centimeters (6–8 inches).

Ceratosaurus ("Horned lizard") was a fairly typical theropod, with a large head, short forelimbs, robust hind legs, and a long tail. Ceratosaurus is from the Late Jurassic Period and is found in the Morrison Formation of North America, in Tanzania and Portugal. It was characterized by large jaws with blade-like teeth, a large, blade-like horn on the snout and a pair hornlets over the eyes. The forelimbs were powerfully built but very short. A row of small osteoderms was present down the middle of the back. The type specimen was an individual about 17.5 feet (5.3 m) long; it is not clear whether this animal was fully grown. It has been estimated that the maximum length of Ceratosaurus was 20 feet (6 m). A particularly large Ceratosaurus specimen from the Cleveland-Lloyd Quarry, discovered in the mid-1960s, may have been up to 30 feet (8.8 m) long.

Chirostenotes ("Narrow-handed") was an oviraptorosaur from the late Cretaceous (80 million years ago) of Alberta, Canada. It was characterized by a beak, long arms ending in powerful claws, long, slender toes and a tall, rounded cassowary-like crest or casque. Chirostenotes was probably an omnivore or herbivore. In life, the animal was about 9.5 feet (2.9 m) long and 3 feet (0.91 m) tall at the hips. It had an estimated weight of about 110 pounds. It probably ate small reptiles and mammals, as well as plants, eggs and insects.

Coelophysis ("Hollow form") is one of the earliest known genera of dinosaur. It was a small, carnivorous biped from North America. It first appeared in the Late Triassic period, around 215 million years ago.

Coelurus is a genus of coelurosaur dinosaur from the Late Jurassic period (mid-late Kimmeridgian faunal stage, 153–150 million years ago). It was not a large dinosaur. Its weight has been estimated at around 13 to 20 kilograms (29 to 44 lb), with a length of about 2.4 meters (7.9 ft) and a hip height of 0.7 meters (2.3 ft). From reconstructions of the skeleton, Coelurus had a relatively long neck and torso due to its long vertebrae, a long slender hindlimb due to its long metatarsus, and potentially a small slender skull.

Compsognathus ("Elegant jaw") was a small, bipedal, carnivorous theropod dinosaur. The animal was the size of a turkey and lived around 150 million years ago, the early Tithonian stage of the late Jurassic Period, in what is now Europe. For decades, Compsognathus was famed as the smallest dinosaur known; the specimens collected were around 1 meter (3 ft) in length. However, dinosaurs discovered later, such as Caenagnathasia, Microraptor and Parvicursor, were even smaller. Compsognathus is estimated to have weighed around 3 kg (6.5 lb). Compsognathus was a small, bipedal animal with long hind legs and a longer tail, which it used for balance during locomotion. The forelimbs were smaller than the hindlimbs and featured three digits equipped with solid claws suited for grasping prey. Its delicate skull was narrow and long, with a tapered snout. The skull had five pairs of fenestrae (skull openings), the largest of which was for the orbit (eye socket). The eyes were large in proportion to the rest of the skull.

Conchoraptor ("Conch thief") was an oviraptorid dinosaur from the late Cretaceous Period of what is now Asia. Conchoraptor was a small dinosaur, of only 1-2 meters (4-6 feet) in length. Unlike many other oviraptorids, Conchoraptor lacked a head crest, although it did lack teeth, a typical oviraptorid characteristic. Its name reflects the hypothesis that oviraptorids, rather than preying primarily upon eggs as had been traditionally thought, may have been specialized to feed on mollusks.

Cryolophosaurus ("Cold crest lizard") was a large theropod dinosaur, with a bizarre crest on its head that looked like a Spanish comb. Due to the resemblance of this feature to Elvis Presley's pompadour haircut from the 1950s, this dinosaur was at one point informally known as "Elvisaurus". Cryolophosaurus was excavated from Antarctica's Early Jurassic Hanson Formation (former the upper Falla Formation) by paleontologist Dr. William Hammer in 1991. It is the first carnivorous dinosaur to be discovered in Antarctica and the first dinosaur of any kind from the continent to be officially named. Dating from the Early Jurassic Period, it was originally described as the earliest known tetanuran, though subsequent studies have found that it is probably more closely related to the dilophosaurs. Cryolophosaurus was about 6 to 8 meters (20 to 26 feet) long, which is significantly smaller than the largest Allosaurus, which reached up to 12 meters (40 feet) in length. A high, narrow skull was discovered, 65 centimeters (25 inches) long. The peculiar nasal crest runs just over the eyes, where it rises up perpendicular to the skull and fans out. It is furrowed, giving it a comb-like appearance. It is an extension of the skull bones, near the tear ducts, fused on either side to horns which rise from the eye sockets (orbital horns). While other theropods like the Monolophosaurus have crests, they usually run along the skull instead of across it.

Daspletosaurus ("Frightful lizard") is a genus of tyrannosaurid theropod dinosaur that lived in western North America between 80 and 73 million years ago, during the Late Cretaceous Period. Fossils of the only named species (D. torosus) were found in Alberta, although other possible species from Alberta, Montana and New Mexico await description. Including these undescribed species, Daspletosaurus is the most species-rich genus of tyrannosaur.

Deinonychus ("Terrible claw") was a genus of carnivorous dromaeosaurid dinosaur. There is one described species, Deinonychus antirrhopus. This 3.4 meter (11 ft) long dinosaur lived during the early Cretaceous Period (Aptian - Albian stages of the cloverly Formation, about 115 million years ago). Fossils have been recovered from the U.S. states of Montana, Wyoming and Oklahoma, though teeth that may belong to Deinonychus have been found much farther east in Maryland.

Deltadromeus ("Delta runner") is a genus of theropod dinosaur from Northern Africa. This carnivore had long, unusually slender hind limbs for its size, suggesting that it was a swift runner. It lived in the late Cretaceous Period, about 95 million years ago. It may have been one of the longest carnivorous dinosaurs, with one unpublished survey indicating that a referred partial specimen could represent an individual that was around 13.3 meters (44 ft) long, though it would have weighed only an estimated 3.5 tons, making it more slender than the giant carnosaurs. The more complete holotype specimen measured an estimated 8.1 m (26.5 ft) long.

Dilong ("Emperor dragon") is a genus of small, tyrannosauroid dinosaur. The only species is Dilong paradoxus. It is from the Lower Cretaceous Yixian Formation near Lujiatun, Beipiao, in the western Liaoning province of China. It lived about 130 million years ago. It was described by Xu Xing and colleagues in 2004. Dilong paradoxus is one of the earliest and most primitive known tyrannosauroids and had a covering of simple feathers or protofeathers, and scales.

Dilophosaurus was a theropod dinosaur from the Early Jurassic Period. The name means "two-crested lizard", because the animal had two crests. Dilophosaurus measured around six meters (20 ft) long and may have weighed half a ton. The most distinctive characteristic of Dilophosaurus is the pair of rounded crests on its skull, possibly used for display.

Dromaeosaurus ("Running lizard") was a genus of theropod dinosaur which lived during the Late Cretaceous period (Campanian), about 76 - 72 million years ago, in the western United States and Alberta, Canada. Dromaeosaurus was a small carnivore, the size of a wolf, about 1.8 m (6 ft) in length and 15 kg (33 lb) in weight. Its mouth was full of sharp teeth and a sharp "sickle claw" on each foot. Although only a few bones are known from the hindlimb, they indicate that Dromaeosaurus was a powerfully built animal. The presence of feathers in closely related animals makes it extremely likely that it was feathered as well. Dromaeosaurus had remarkably large eyes and excellent vision. It also probably had a good sense of smell and hearing. Its neck was curved flexible and its jaws were solidly built. The tail was flexible at the base but sheathed in a lattice of bony rods; this allowed it to be carried in a sharply upturned position.

Dromiceiomimus ("Emu mimic") was a swift bipedal dinosaur from the late Cretaceous period, about 80 million to 65 million years ago. It was about 3.5 meters (12 ft) long and weighed about 100 to 150 kilograms (220 to 330 lb). Its femur (thigh bone) was 46.8 centimetres (18.4 in) long. This ornithomimid (a bird-like theropod) had very long limbs, hollow bones, and a large brain and eyes. It had a toothless, beaked mouth, and weak jaws. The brains of ornithomimids were large for dinosaurs, but this may not necessarily be a sign of greater intelligence; some paleontologists think that the enlarged portions of the brain were dedicated to kinesthetic coordination. Compared to other ornithomimosaurs Dromiceiomimus had a short back, long slender forearms, very large eye sockets, and pelvic bones that were arranged somewhat differently.

Elaphrosaurus (meaning "Lightweight lizard") is a genus of carnivorous theropod dinosaur from the late Jurassic of Tanzania, 145 mya. Elaphrosaurus was probably a ceratosaur about 6 meters (20 ft) long. What is known about Elaphrosaurus mostly comes from a single nearly complete skeleton. No skull has been found. It was long and slender, with a long neck, possibly for digging into carrion. It was about 6.2 meters (20 ft) long, 1.46 meters (4.79 ft) tall at the hip, and weighed about 210 kilograms (460 lb). The tibia (shin bone) of Elaphrosaurus was considerably longer than its femur (thigh bone), which indicates that it could probably run very fast.

Eoraptor was one of the world's earliest dinosaurs. It was a two-legged meat-eater that lived between 230 and 225 million years ago, in what is now the northwestern region of Argentina. It had a thin body that grew to about 1 meter (3 ft) in length, with an estimated weight of about 10 kilograms (22 lb). It ran digitigrade, upright on its hind legs. Its fore limbs were only half the length of its hind limbs and it had five digits on each "hand". Three of those digits, the longest of the five, ended in large claws and were presumably used to handle prey. Scientists have surmised that the fourth and fifth digits were too tiny to be of any use in hunting. Eoraptor probably ate mostly small animals. It was a swift sprinter and, upon catching its prey, it would use claws and teeth to tear the prey apart. However, it had both carnivore-type and herbivore-type teeth, so it could possibly have been omnivorous. Paleontologists believe the Eoraptor resembles the common ancestor of all dinosaurs. It is known from several well-preserved skeletons.

Eotyrannus ("Dawn tyrant") was a genus of tyrannosauroid theropod dinosaur hailing from the Early Cretaceous Wessex Formation beds, included in Wealden Group, located in the southwest coast of the Isle of Wight, United Kingdom. Eotyrannus is a 6 meter-long theropod which has the following tyrannosauroid characters: serrated premaxillary teeth with a D cross section, proportionally elongate tibiae and metatarsals. Primitive characters for Tyrannosauroidea are the elongate neck vertebrae and the long, well-developed arms forelimbs along with the undecorated dorsal surface of the skull, unlike the more advanced tyrannosaurids. However this animal, proportionally, has one of the longest hands in Theropoda known to date.

Eustreptospondylus ("Well-curved vertebra") was a genus of megalosaurid dinosaurs from the Callovian stage of the Middle Jurassic period (164.7-161.2 million years ago) in southern England, at a time when Europe was a series of scattered islands. The only known specimen of Eustreptospondylus may not be fully grown, and was about 4.63 metres (15.2 ft) long. It was carnivorous, bipedal and had a stiffened tail. It was a typical theropod, with powerful hind limbs, erect posture and small forelimbs.

Fukuiraptor was a medium-sized carnivore of the Early Cretaceous (Barremian) that lived in what is now Japan. Scientists first thought it was a member of the Dromaeosauridae, but after studying the fossils they now believe it was related to Allosaurus. The type specimen is the skeleton of an individual about 4.2 metres long. It is thought that this specimen was not mature and an adult may have been larger.
