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.

It is a large theropod carnivorous dinosaur that lived in northern Africa during the mid Cretaceous period, famous for its unique sail like dorsal spine and body shape adapted to aquatic life. It is one of the largest known carnivorous dinosaurs. The head is long and narrow, similar to modern crocodiles, with straight conical teeth that lack serrated edges and are suitable for hunting fish. The dorsal nerve spines are very tall, forming unique sail like structures that may be used to regulate body temperature, attract the opposite sex, threaten opponents, or attract prey. The living environment includes wetlands such as rivers, lakes, and swamps, and is active on land and near water, preying on fish and other aquatic animals.

Velociraptor is a small dinosaur genus that lived in Asia during the late Cretaceous period (approximately 75 to 71 million years ago). Currently, two species have been identified, although other species have been assigned in the past. The species of this type is V. mongoliensis, named and described in 1924. The fossil of this species has been discovered in the Djadochta Formation of Mongolia. In 2008, the second species, V Osmolskae is named after the skull material from the Bayan Manda Lake Formation in China.

Triceratops is a genus of ceratopsian dinosaurs that lived in the late Cretaceous Maastrichtian era in present-day western North America. It is one of the last known non avian dinosaurs that lived until the Cretaceous Paleogene extinction event 66 million years ago. The name Triceratops means "triangular face", derived from the Greek words tr í - meaning "three", k é ras meaning "horn", and ṓ ps meaning "face".

Spinosaurus is a large theropod dinosaur with a body length comparable to that of Tyrannosaurus Rex and Southern Megalosaurus. There is currently only one valid species in the genus Spinosaurus, namely the Egyptian Spinosaurus, named by German paleontologist Stromer in 1915. Due to its unique appearance and massive size, Spinosaurus has received no less attention than Tyrannosaurus rex. Unfortunately, the holotype specimen of Spinosaurus was destroyed during World War II. For a long time, paleontologists' understanding of Spinosaurus has only been limited to photos of holotype specimens and a few fossil fragments. With the gradual increase of fossil evidence in recent years, the true image of Spinosaurus has emerged.

For a long time, paleontologists' understanding of Spinosaurus has only been limited to photos of holotype specimens and a few fossil fragments. With the gradual increase of fossil evidence in recent years, the true image of Spinosaurus has emerged. It is a type of dinosaur with good water properties.

There is currently only one valid species in the genus Spinosaurus, namely the Egyptian Spinosaurus, named by German paleontologist Stromer in 1915. Due to its unique appearance and massive size, Spinosaurus has received no less attention than Tyrannosaurus rex. Unfortunately, the holotype specimen of Spinosaurus was destroyed during World War II. In recent years, new fossil specimens and quantitative studies have shown that Spinosaurus had a highly specialized body structure and was a highly aquatic dinosaur. Spinosaurus is one of the longest carnivorous dinosaurs. Spinosaurus is 10 to 15 meters long and weighs 3 to 10 tons. The World of Animals
