Fossil skull of Jilong

Jilong, also known as Stingshield Ceratosaurus, lived in the late Cretaceous period and is a type of herbivorous ceratopsian dinosaur. The head of the neck shield Jilong was large, with a beautiful shield shaped circular decoration on its neck. There are six long horns of different sizes growing around the shield shaped ornaments, which make up the terrifying neck shield of the halberd dragon. This neck shield can not only scare enemies. This neck shield usually looks spectacular and beautiful on strong and powerful males, while it is not well-developed on females. Therefore, 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 the halberd in ancient Chinese weapons, it is vividly named Jilong.
