Nicrosaurus is a genus of sauropods in the order Ceratopsiformes. Their appearance and lifestyle may resemble crocodiles, but they are not closely related to crocodiles and are the result of parallel evolution. The main difference between Nicosaurus and crocodiles lies in the position of their nostrils. Nicosaurus' nostrils are located on the forehead, while crocodiles' nostrils are located at the end of their mouth and nose. It is a herbivorous dinosaur.

The swollen headed dragon is a member of the thick headed dragon family in the order Ornithischia of the class Sauropods. The swollen headed dragon, also known as the thick headed dragon, has a thick bone plate on its head, which can reach a thickness of over 20 centimeters, and is raised high like a tumor. The body length is 4-6 meters and the weight is 0.5-4 tons. The area around the head and nose tip are also covered with small bone tumors, and some have large and sharp spines behind the head. Living in the late Cretaceous period, mainly distributed in North America, inhabiting plains, deserts, and other environments. Sexually inclined to live in groups, males fight in the form of "heads", with the winner being the leader of the entire group and occupying the female dinosaur. A herbivorous dinosaur that feeds on fruits, leaves, and other food.

The Pterosaur is a member of the Hadrosauridae family in the order Ornithischia, also known as the Pterosaur. The most obvious feature is the crown extending from the head, which is rod-shaped and longer than other crowned dinosaurs. There is a thin tube in the crown of the head that makes a sound when air passes by, and the secondary comb dragon uses it for "conversation". The forelimbs of the Pterodactylus can support its body, swim, and wade through water. Living in the late Cretaceous period, this organism was discovered in North America and lived along inland waterways. Eating plants, the habitat is home to many evergreen trees, ferns, and a small number of flowering plants. Collective living, with a keen sense of hearing and smell, will use a headband to sound an alarm signal when danger is detected.

The Fanguan Swan Dragon is a member of the subfamily Lycosaurinae in the duck billed dinosaur family. Fossils were discovered in the Chagayan Formation near Kundur, Amur Oblast, Russian Far East, dating back to the middle or late Maastrichtian stage of the Late Cretaceous period. Like other hadrosaurids, the fancrown swan dragon is a herbivorous dinosaur that can walk on two or four legs, has a complex skull, can perform chewing like grinding actions, and has hundreds of constantly growing and replacing teeth. The tall, wide, hollow crown decoration of the fancrown swan dragon, which includes a nasal tube inside, may be used as a visual recognition object or auditory speaker.
