Spinosaurus was a large theropod carnivorous dinosaur that lived in the middle of the Cretaceous period, mainly in the estuarine delta region of northern Africa. It is one of the longest known carnivorous dinosaurs. The most prominent feature is the long spines on its back, which are extended by the nerve spines of the vertebrae to form a structure similar to a ship's sail. May be used to regulate body temperature, store fat, attract the opposite sex, or threaten an opponent. Is a semi-aquatic animal with body structures adapted to aquatic life, such as long, narrow upper and lower jaws and sharp teeth, suitable for catching fish and other small animals. The hydrophilicity increases in the high temperature season.

Megalosaurus, also known as Southern Megalosaurus, is a large carnivorous dinosaur that lived in the middle of the Cretaceous period, belonging to the theropod suborder sharkodosauridae. It was one of the largest terrestrial carnivorous dinosaurs of its time, smaller only than Spinosaurus and Tyrannosaurus. Large size, huge head, narrow mouth, sharp teeth, up to 20cm long, suitable for biting and hunting. The forelimbs are short, the hind limbs are stout, and they walk on two feet. Fossils were first discovered in Argentina in 1993, mainly in the Patagonia region of Argentina. The top predators in the ecosystem at the time were known for their strong predation and large size.

Stegosaurus is a large herbivorous dinosaur that lived in the late Jurassic period and belongs to the family Swordosaurus. The body length can reach 7-9 meters, the height is 2.35 to 3.5 meters, and the weight is about 2 to 4 tons. The most notable feature is a row of huge triangular bone plates on the back, which may be used to regulate body temperature, display or defense. The tail ends with four long spines for defense against predators. With a small head and relatively small brain volume, it is considered a less intelligent dinosaur. It walks on four legs and feeds mainly on low plants. Found mainly in North America and Asia, it is one of the most famous dinosaurs of the Jurassic period.

It is a giant carnivorous dinosaur that lived in the late Cretaceous period about 66 million years ago. Known for its massive size and powerful hunting ability, it was one of the top predators on land at that time. The body length can reach about 12 meters, and the estimated weight is between 5 and 7 tons. The head is huge, with strong jaws and sharp teeth, capable of easily tearing prey apart. The forelimbs are short, but the hind limbs are well-developed, suitable for fast running. Tyrannosaurus rex is an iconic species of the dinosaur era, with fossils found in North America, particularly in the western regions of the United States and Canada.

It is a large carnivorous dinosaur that lived from the late Jurassic to early Cretaceous period. He was one of the most powerful predators on land at that time, known for his enormous size and powerful hunting ability. The body length is usually between 8 and 12 meters, and the weight can reach about 2 tons. Having strong hind limbs and sharp claws, it is very suitable for fast running and catching prey. The head is particularly large, with strong jaw muscles and sharp teeth, which can easily tear apart prey. Although their forelimbs are relatively small, they are still very powerful and can help them secure their prey during hunting. Fossils have been found in both North America and Africa.

It is a large herbivorous dinosaur from the Jurassic period. Living approximately 150 million years ago, mainly distributed in today's North America region. Known for its enormous size and unique skeletal structure, adult individuals can grow up to 20 to 30 meters in length and weigh up to 20 to 30 tons. The neck is very long, making it easy to forage for plants at high altitudes. The head is small with spoon shaped teeth, suitable for chewing hard plants. Belonging to the suborder Sauropod dinosaurs, it is one of the earlier members of this group. Strong limbs, adapted to walking on open plains. The tail is very long and may be used to maintain balance or as a defensive tool.

Stegosaurus is a giant theropod dinosaur belonging to the theropod suborder, which lived in southern Mongolia during the late Cretaceous period, about 70 million years ago. It belongs to the Stegosauridae family in the ornithopod suborder and is one of the largest ornithopod dinosaurs and theropod dinosaurs. It is 12 meters long and weighs 9.3 tons, with arms 2.5 meters long and claws 25 centimeters long. It is a giant omnivorous dinosaur and the largest theropod dinosaur discovered in Asia.

The Tyrannosaurus genus is a member of the Tyrannosauridae family, and the only valid species is the type species Tyrannosaurus rex, also known as the Rex dinosaur. It is a large carnivorous dinosaur with a length of about 15 meters, a hip height of about 5 meters, and a weight of about 8 to 13 tons. Tyrannosaurus lived in the Maastrichtian stage of the late Cretaceous period, approximately 67 to 66 million years ago, and was one of the last dinosaur populations before the Cretaceous Tertiary extinction event. Fossils are distributed in the western United States and Canada in North America, with a wider distribution range than other tyrannosaurids.
