Top 3 in Top 10 Most Popular Dinosaurs.
In the late Jurassic period, there was a very ferocious carnivorous dinosaur, Ceratosaurus. From the appearance, it is not much different from other carnivorous dinosaurs. They have big heads, thick waists, long tails, and walking on two feet. The forelimbs are short, the jaws are strong, and the mouth is covered with sharp, curved teeth. But there is a short horn above the nose, and there are similar short horn protrusions in front of both eyes, which may be why it is called Ceratosaurus. In addition, the head also has small serrated spinous.
Ceratosaurus mostly live in the fern savannahs of western North America and the forested alluvial plains in the late Jurassic period, and generally choose to hunt large prey in groups. What is the role of the horns on Ceratosaurus? Some paleontologists believe that this horn is used for defense or fighting, but this horn does not seem to be large, and it seems that it cannot be used for fighting. Other paleontologists have speculated that this horn is only a decoration and has no practical purpose. Male ceratosaurus may decide the position according to the size of the horn. Whoever has the largest horn will become the leader of the group.
