It is a genus of pterosaurs in the Pterosauridae superfamily, a large pterosaur with a crown and no teeth. Fossils were discovered in the Santana Formation in Brazil, dating back to the early Cretaceous period. The appearance resembles that of a toothless pterosaur, with the adult individual's head crown extending from the snout to the back of the head. The head crown of a fairy pterosaur is larger and more prominent than that of a toothless pterosaur. Both males and females have large crests, but females have relatively round crests. The body length is 2.5 meters, the wingspan is 5.4 meters, and the length of the skull is 90 centimeters. They seem to live along the coasts of South America, feeding mainly on fish.

Brachiosaurus is a general term for the "Brachiosaurus genus" dinosaurs of the Jurassic period. The body length is 25 meters, the height is 15 meters, the weight is 30 tons, the tail is thick and short, the head is small, the neck is long, and the appearance is similar to that of a giraffe; There are large claws on the inner side of the forefoot; The jaw is well-developed, with 52 teeth covering the upper and lower parts, and the edges of the teeth are sharp; Strong limbs; The nostrils grow on the top of the head. Named after its long forelimbs. The head is very small and it is a dinosaur with low intelligence. Living in North America during the late Jurassic period and North Africa during the early Cretaceous period. It inhabits grasslands filled with ferns, cycads, and wood thieves. Mild temperament, enjoys living in groups. Feed on leaves and tender branches. Often foraging together.

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. It is a type of dinosaur with good water properties.

Parrotbeak Dragon, also known as Parrotbeak Dragon, meaning "parrot lizard" in Greek, is a genus of Parrotbeak Dragon family in the suborder Ceratopsia. It lived in Asia during the Early Cretaceous period, approximately 123.2 to 110 million years ago. Parrotbeak dinosaur, as well as Protoceratops, Triceratops, and other dinosaurs, all had a parrot like hooked beak. Scientists infer from its body shape and age that Parrotbeak dinosaur may be the ancestor of most ceratopsian dinosaurs. It is a small herbivorous dinosaur named after its parrot like beak. They are very early ceratopsian dinosaurs that independently developed many features.

Jilong is a medium-sized spinosaurus, whose fossils were discovered in Brazil during the Early Cretaceous period. At present, there is only one species under the genus Jilong, which is the type species Chalinjie Jilong. Fossil materials of Jilong are also very rare, but what is slightly better than other similar specimens is that the holotype specimen of Jilong is a well preserved skull. Although the snout is missing, the latter half of the mouth and skull are preserved, which can provide more information for phylogenetic analysis and other research.
