Top 10 Dinosaurs in the World

Since 1822, the first discovery of Iguanodon dinosaur fossils in Manchester, England, marked that dinosaur fossils quickly became popular exhibits in museums around the world due to their unique structure and obvious differences from modern creatures. At the first World Expo, dinosaur fossils were displayed in the Crystal Palace in London; and the first exhibition dedicated to dinosaurs appeared in 1852, called the Dinosaur Crystal Palace, which is still preserved as a historical building in the UK.

As more and more dinosaur fossils are discovered, people's understanding of this creature is also deepening. Now, let's take a look at the top ten dinosaurs in the world and explore together!

1. The longest dinosaur in the world: Seismosaurus

Seismosaurus is considered to be the longest dinosaur in the world. It is initially estimated that its body length is between 42 and 67 meters and its weight exceeds 100 tons. These estimates were later revised down to 33 to 33.5 meters, and then to 32 meters.This dinosaur lived in the late Jurassic period, about 136 million to 162 million years ago. Because of its huge body, the ground seemed to be shaking when it walked, so it was named "Seismosaurus", which is extremely appropriate.

Despite its huge size, Seismosaurus is a staunch vegetarian. However, due to its small head and mouth, it eats relatively slowly, so Seismosaurus spends most of its daily life eating, which is a veritable "big foodie", and because of its huge size, almost no one dares to provoke it.

2. The world's largest dinosaur: Diplodocus fragilis

Diplodocus fragilis is considered to be the longest dinosaur known on Earth, and its length even exceeds that of the largest animal today, the blue whale (33 meters), reaching 40 to 58 meters. However, in terms of weight, Diplodocus fragilis (heaviest up to 150 tons) is still inferior to the blue whale (181 tons), after all, the blue whale is the heaviest known animal on Earth.

3. The world's largest carnivorous dinosaur: Spinosaurus

Spinosaurus is usually between 12 and 20 meters long and weighs between 4 and 26 tons, which is larger than Tyrannosaurus Rex. In this type of carnivorous dinosaur, size usually means stronger combat power, so many people believe that Spinosaurus is more powerful than Tyrannosaurus Rex. Spinosaurus, which reaches 20 meters in length, is considered one of the largest prehistoric carnivorous dinosaurs.

4. The dinosaur with the longest neck in the world: Mamenchisaurus

Do you know which prehistoric dinosaur has the longest neck? Mamenchisaurus is one of the largest sauropods discovered in China. It has the longest neck of all dinosaurs. Its neck can reach 12.1 meters, which is much longer than that of Diplodocus. Mamenchisaurus' neck accounts for about half of its body length. It mainly feeds on juicy aquatic plants and lived about 140 million years ago.

5. The smallest dinosaur in the world: Compsognathus

In the eyes of many people, dinosaurs are huge creatures, often with a body length of dozens of meters. However, do you know? Compsognathus is a bipedal carnivorous theropod dinosaur, but their body size is only about the same as that of modern turkeys. It is considered one of the smallest dinosaurs in ancient times. This dinosaur lived in Europe about 150 million years ago.

6. The most ferocious dinosaur in the world: Giganotosaurus

The largest individual of Giganotosaurus is 13.8 meters long, with a hip height of 4 meters, a total height of about 4.2 meters, and a weight of up to 10.52 tons. Compared with the largest dinosaur in history, Seismosaurus, it is much smaller. With a narrow mouth, Giganotosaurus is equipped with sharp but relatively thin teeth. 

It has a strong bite force and the ability to bite quickly, and its teeth are as sharp as a table knife. When walking, it relies on two short legs. Judging from the ratio of leg length, height and body length, Giganotosaurus is one of the shortest carnivorous dinosaurs in proportion.

7. The dinosaur with the longest claws in the world: Therizinosaur

The fossils of Therizinosaur were first discovered in the Gobi Desert in Mongolia. At first, it was not sure what kind of creature it belonged to, which caused a lot of fun. Some people thought it was an unknown turtle, while others speculated that it was a raptor dinosaur. 

It was not until a huge forearm bone fossil and some hook claw fossils were discovered again in Mongolia that these clues were combined and confirmed that this was a new type of dinosaur. The front claws of Therizinosaur were as long as 0.75 meters, hence the name, making it one of the creatures with the largest claws among known animals.

8. The most intelligent dinosaur in the world: Allosaurus

Allosaurus, also known as Leaposaurus or Allosaurus, is a predatory dinosaur that lived in the Late Jurassic period, about 155 million to 135 million years ago. They can reach 8.5 meters in length, the largest individual can reach 9.7 meters, weigh between 1.5 and 3 tons, and the heaviest can reach 3.6 tons. Allosaurus was the most common large predator in the Morrison Formation of North America at that time, and was at the top of the food chain.

9. The world's loudest dinosaur: Brontosaurus

Brontosaurus is named for its deafening roar and is considered the loudest dinosaur in history. It can weigh more than 27 tons and is about 30 meters long, with a tail of 9 meters long. In the dinosaur era, Brontosaurus was a very well-known dinosaur species!

10. The most docile dinosaur in the world: Maiasaura

Maiasaura is a large hadrosaur dinosaur, medium-sized, about 9 meters long; with a typical hadrosaur flat beak and a thick nose. Maiasaura will give birth to cubs in the nest and take good care of them, very kind. 

This characteristic makes them different from many other dinosaurs, so scientists call them "the most docile dinosaurs."
