Everyone knows dinosaurs. We can see dinosaurs in dinosaur cards and some television dramas and cartoons. So, what are the types of dinosaurs? Topshare has compiled list about top ten most popular dinosaurs species.
1 Stegosaurus
Stegosaurus is a huge herbivorous dinosaur. It is a herbivorous animal that lived in the late Jurassic period. It has a large row of bone plates on its back and a dangerous tail with four spikes to defending against attacking predators, about 7-9 meters long, 2.35 meters to 3.5 meters high, and weighed 2 to 4 tons. They live on the plains and live in groups.
The stegosaurus is one of the most well-known dinosaurs, and it can be seen in movies, cartoons, comics or toys. In addition, the State of Colorado in the United States declared Stegosaurus a "State Dinosaur" in 1982.
2 Archaeopteryx
Archaeopteryx is a small dinosaur that lived in the late Jurassic period. It belongs to the suborder of Deinonychus and represents a primitive type of Deinonychus.
It lived in the early Titonian stage of the Jurassic Period, about 155 million to 150 million years ago. These specimens were found only in Germany. Fossils are distributed in southern Germany.
3 Ceratosaurus
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.
4 Diplodocus
Diplodocus is a dinosaur of the Diplodocidae. Its bone fossils were first discovered by Samuel Wendell Williston. Diplodocus lived in western North America at the end of the Jurassic period, dating from 150 million to 147 million years ago. They can exceed 30 meters in length and weigh about 10 tons.
Diplodocus is one of the most easily identified dinosaurs, with a huge body, long neck and tail, and strong limbs. Many years ago it was considered the longest dinosaur.
5 Allosaurus
Allosaurus is a medium-sized carnivorous dinosaur. It is 8.5 meters long, 9.7 meters in maximum, weighs 1.5 to 3 tons, and heaviest 3.6 tons. They lived in the late Jurassic, from about 155 million years to 135 million years ago. Since being named by Othniel Charles Marsh in 1877, many possible species have been classified under the Allosaurus genus, but only a few are considered valid species. Allosaurus is very clever and will besiege large prey. It is a huge, fierce carnivorous dinosaur.
