In 1942, a larger theropod dinosaur was discovered in the Early Jurassic strata of Arizona, USA. Because it had a pair of thin V-shaped bony ridges on the top of its head, paleontologists named it Bi. Spinosaurus.
Dilophosaurus has a stout body, a tall skull, well-developed jaws, a large mouth, and a mouth full of teeth like sharp knives. There are small serrations on the front and rear edges of the teeth. These features show that it can tear apart anything it captures. It catches prey and then swallows chunks of meat into its belly. In addition, there are holes in the skull of Dilophosaurus behind the eyes. These holes are used to better attach the muscles that affect the jaws, so the bite of Dilophosaurus must be very powerful. Paleontologists speculate that Dilophosaurus may have been the most ferocious and ferocious carnivore in the Early Jurassic ecosystem.
The hind limbs of Dilophosaurus were thick and powerful, and the feet had sharp claws that could be used to capture and tear prey. During that period of time around 200 million years ago, Dilophosaurus often appeared in the highlands or jungles between rivers and lakes, hunting down various vegetarian animals. They may also like to live alone, and sometimes they may hide in places where they are not easily discovered, waiting for opportunities to sneak up on prey. They may even feed on the carcasses and carrion of dead animals for various reasons like vultures.
Fossils of Dilophosaurus have also been discovered in Jinning County, Yunnan Province, my country. Dilophosaurus sinensis was the largest carnivorous dinosaur in the Early Jurassic, with a length of nearly 4 meters and a sharp and long mouth. Paleontologists speculate that its favorite food was probably the internal organs of other animals, because its sharp beak can be inserted into the abdominal cavity of animal corpses, and the two thin plate-like crown ridges on the top of its head can be inserted into the abdominal cavity of the corpse. It plays the role of supporting the cavity wall.
Dilophosaurus is also a member of the Tethys Sea fauna, so the species found around the world are similar. Their fossils have also been found in Antarctica, indicating that Antarctica, which is now covered with ice and snow, was a warm paradise for dinosaurs at that time.
