Stardosaurus (Styracosaurus), also known as shield-horned dinosaur, means "lizard with spikes (στυ ραξ)" in Greek. It is a genus of herbivorous horatosaurus dinosaurs and lived in the Cretaceous Campanidae, about 76.5 million to 75 million years ago.

Cockerosaurus is a herbivorous dinosaur of the genus Cockerosaurus of the ornithopterosaurus family. Its Latin name means "open and split reptile", and it is also known as Gasperosaurus and Cracerosaurus. Its body length is 4.8-6 meters, its weight is 3.6 tons, its head shield is wide and heart-shaped with holes, its nose has short corners, and its frontal horn length varies by sex. The dorsum has a tumor-like protrusion 5cm in diameter, and the neck fold leaf structure is longer than that of Triceratops. The known species include Billerosaurus, Canadian killerosaurus, etc. Some fossils have been classified as agouhaerosaurus. The species lived in Late Cretaceous North America, and most fossils were found in Alberta, Canada.

Halbersaurus, also known as Spiny Shield Ceratopsian, lived in the late Cretaceous period and is a type of herbivorous ceratopsian dinosaur. The neck shield halbersaurus had a large head and beautiful shield shaped circular decorations on its neck. Around the shield shaped ornament, there are six long horns of different sizes, which form the terrifying neck shield of the halberd dragon. This neck shield can not only scare the enemy. This neck shield usually looks spectacular and beautiful on strong and powerful males, but is not well-developed on females, so experts speculate that its main function is to showcase and attract the attention of the opposite sex. Because this neck shield looks very similar to a halberd in ancient Chinese weapons, it was named Jilong figuratively.

It is a dinosaur that lived during the Late Cretaceous period, known for its prominent head features, having a huge bony neck shield and three horns, with the largest two horns located above the eyes and a smaller horn located above the nose. Belonging to the Ceratopsidae family, it is a herbivorous dinosaur with a huge body size, measuring about 6 to 9 meters in length and weighing up to several tons. Mainly distributed in today's North America region. Neck shields are believed to be used to protect them from predators and may also be used for display or courtship. Teeth have adapted to grind plants, indicating that they primarily feed on low growing plants. It is one of the important species in paleontological research.

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".
