As only the skull is known, it has proven difficult to provide a reliable size estimate of Abelisaurus. It has transpired that abelisaurids have relatively short heads.

Tyrannosaurid forelimbs were extremely small for their body size and retained only two digits.

Bird-like dinosaurs that is transitional between non-avian feathered dinosaurs and modern birds.

The bird's skull is larger than that of small horses.

Early meat-eating dinosaurs like Coelophysis relied on their speed and agility to catch a variety of animals like insects and small reptiles. The sharp teeth and grasping claws of Coelophysis would have helped them to hold and kill their food.

Glyptodonts are a member of the family which also includes some modern armadillo species.

Its teeth were larger with greater shearing ability, and its bite force at the canine tooth was the strongest of any Canis species.

Erlikosaurus were therizinosaurs, a strange group of theropods that ate plants instead of meat, and that had backward-facing pubises like ornithischians.

Gorgosaurus was smaller than Tyrannosaurus or Tarbosaurus, closer in size to Albertosaurus and Daspletosaurus.

Extinct giant goanna or monitor lizard.

The curved upper and lower jaws of Oviraptor would have been able to crush even hard objects.

Although commonly known as the saber-toothed tiger, it was not closely related to the tiger or other modern cats.

The creature also makes effective use of razor-sharp claws to latch onto surfaces such as the trunks of tall trees, holding its position indefinitely. Warlike tribes appear to consider Tapejara the equivalent of a versatile rotor aircraft, capable of rapid positional changes and aggressive agility.

The swift minnow.

It was probably an active bipedal predator, hunting with the large sickle-shaped claw on the second toe of each hind foot.

Alectrosaurus was a very fast running tyrannosauroid as indicated by the elongated hindlimbs that likely filled the niche of a pursuit predator, a trait that seems to be lost by the advanced and robust tyrannosaurids.

Baryonyx is one of the largest fish eating-dinosaurs and comes from the spinosaurid family

Carcharodontosaurus were carnivores, with enormous jaws and long, serrated teeth up to eight inches long.

The first carnivorous dinosaur to be discovered in Antarctica and the first dinosaur of any kind from the continent to be officially named.

It had a pair of longitudinal, plate-shaped crests on its skull, similar to a cassowary with two crests. The function of the crests is unknown; they were too weak for battle, but may have been used in visual display, such as species recognition and sexual selection.

The back foot of this dinosaur had a large claw for kicking.

One of the largest known terrestrial mammalian carnivores that has ever existed.

The skull of Majungasaurus is exceptionally well-known compared to most theropods and generally similar to that of other abelisaurids. Like other abelisaurid skulls, its length was proportionally short for its height, although not as short as in Carnotaurus.

Metriacanthosaurus was a medium-sized theropod with a femur length of 80 cm.

Pteranodon had a wingspan of 7 metres (23 feet) or more, and its toothless jaws were very long and pelican-like.

Non-avian feathered dinosaur.

Titanoboa was vaguely similar to modern-day constrictors, but only it was much larger. In fact, it is the largest species of snake that had ever lived on planet Earth.

Yangchuanosaurus was a large, powerful meat-eater. It walked on two large, muscular legs, had short arms, a strong, short neck, a big head with powerful jaws, and large, serrated teeth.

Like Velociraptor dinosaurs, it was bipedal with a big, sickle-like claw on each foot.

The skull had a pair of horns above and in front of the eyes. The horns were probably covered in a keratin sheath and may have had a variety of functions, including acting as sunshades for the eye, being used for display, and being used in combat against other members of the same species.

Only partial hindlimbs of this dinosaur have been found, so reconstructions are speculative. It was named after Lewis Carroll's borogoves from the poem Jabberwocky, published in 1871.

Carnotaurus was highly specialized and distinctive. It had thick horns above the eyes, a feature unseen in all other carnivorous dinosaurs, and a very deep skull sitting on a muscular neck. 

The type species is Daeodon shoshonensis is the last and largest of entolodonts.

Dimorphodon means "two-form tooth", derived from the Greek δι (di) meaning "two", μορφη (morphe) meaning "shape" and οδων (odon) meaning "tooth", referring to the fact that it had two distinct types of teeth in its jaws – which is comparatively rare among reptiles.

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.

 It is one of the largest known terrestrial carnivores, slightly larger than Tyrannosaurus, but smaller than Spinosaurus.

The most distinctive characteristic of Masiakasaurus is the forward-projecting, or procumbent, front teeth.

Mosasaurus were marine reptiles which closely related to snakes and monitor lizards

The largest known flying animal to have ever lived.

According to recent estimates, Spinosaurus is the largest of all known carnivorous dinosaurs, even larger than Tyrannosaurus rex and Giganotosaurus. 

Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs.
