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".

Tyrannosaurus rex, also known as Tyrannosaurus rex, is a type of theropod dinosaur and the most representative large theropod dinosaur. Tyrannosaurus rex once roamed an island continent called Laramidia (now located on the eastern foothills of the Rocky Mountains in western North America). The distribution range of tyrannosaurs is wider than other members of the tyrannosauridae family. Its fossils were discovered in various strata of the Late Cretaceous Maastrichtian stage (approximately 68 to 66 million years ago). Tyrannosaurus is the last known member of the Tyrannosauridae family before the Cretaceous Paleogene extinction event, and is also one of the latest non avian dinosaurs to go extinct. Tyrannosaurus rex is currently the heaviest known carnivorous dinosaur.

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.
