The Ten Largest Dinosaurs_Top Ten Dinosaur Size Rankings

As we all know, prehistory was dominated by animals, and they were all huge super animals, especially dinosaurs, which were definitely the largest animals in the world at that time. Let's take a look at the ten largest dinosaurs in prehistory.

1. Fragile double-chambered dragon

The largest dinosaur

Amphilaeus fragilis was excavated by fossil collector Oramel Lucas in 1877. It is the longest and heaviest dinosaur in history, and its maximum weight is even larger than the blue whale. It is 35 meters long and is closely related to Diplodocus. It lived in the late Jurassic period and was distributed in North America. It was 70 meters long and weighed up to 190 tons, which is equivalent to the total weight of 40 elephants. It was 10 meters high at the hips and 15 meters high at the head.

2. Puertalosaurus reesei

The second largest dinosaur

Puertaosaurus reesei is considered to be one of the largest dinosaurs on earth. Its chest can hold an elephant, making it the "King of Dinosaurs". Living in North America during the Cretaceous period, it was 50 meters long, weighed 110 tons, and had vertebrae 1.06 meters high and 1.68 meters wide.

3. Argentinosaurus

The third largest dinosaur

Argentinosaurus belongs to the titanosaur class of sauropod dinosaurs, named after the dinosaur found in Argentina. Living in the middle of the Cretaceous period 100 million years ago, it is one of the largest land dinosaurs discovered so far. Distributed in South America, Argentinosaurus is 40 meters long and weighs up to 90 tons. Among all modern creatures, only the blue whale is larger than it.

4. Super Dragon

The fourth largest dinosaur

Chaosaurus is also translated as Superosaurus, which means "super lizard". It is a diplodocoid dinosaur. The fossil of Supersaurus was discovered in 1972 in the Morrison Formation of Colorado, USA. Living in North America during the late Jurassic period, it was 38 meters long, weighed 60 tons, and had only one spine 1.4 meters long.

5. Poseidonosaurus

The fifth largest dinosaur

Poseidonosaurus, also known as Poseidon and Poseidon, is a herbivorous dinosaur and a sauropod dinosaur that lived in the Early Cretaceous and is closely related to the more famous Brachiosaurus. Living in North America, it can reach a length of 35 meters, a height of 17 meters, and a weight of 55 tons. Only one specimen has been found so far, consisting of four cervical vertebrae. It was discovered in Oklahoma, USA, in 1994.

6. Earthquake Dragon

The sixth largest dinosaur

Seismosaurus means "earth-shaking lizard" and is one of the larger herbivorous dinosaurs that lived in the late Jurassic period. Zhensaurus was 32 meters long and weighed 30 tons. The tail is slightly longer than the neck and the head is small. The fossil was discovered in New Mexico in 1979. The nostrils are located at the front of the snout, but the nostril holes on the skull are located at the top of the head, and the forelimbs are slightly shorter than the hind limbs.

7. Diplodocus

The seventh largest dinosaur

Diplodocus, whose skeleton was first discovered by Samuel Wendell Williston. Diplodocus lived in western North America at the end of the Jurassic period, dating back to 150 to 147 million years ago. Individuals can be over 30 meters long and weigh about 10 tons. The nostrils are located above the eyes. Their necks cannot be raised, presumably to expand the eating area in place.

8. Brachiosaurus

The eighth largest dinosaur

Brachiosaurus is a genus of sauropod dinosaur that lived in the late Jurassic. Its forelimbs are much larger than its hind limbs. Brachiosaurus was one of the largest animals that ever lived on land, with a body length of about 25 meters, a height of 13 meters, and a weight of up to 40 tons.

9. Apatosaurus

The ninth largest dinosaur

Apatosaurus, also known as Apatosaurus, belongs to the genus Apatosaurus in the family Diplodocidae, including A. ajax and A. louisae. It weighs 30 tons. According to the newly discovered dinosaur thigh bone in Argentina, it is 4-5.5 meters tall and about 35 meters long. Lived in the late Jurassic period and was distributed in the American continent.

10. Mamenchisaurus

The tenth largest dinosaur

One of the largest sauropod dinosaurs discovered in China, its fossil was found at the Maming River Ferry in Yibin City. After scientific identification, it belongs to the order of sauropods. This animal is about 22 meters long and nearly 7 meters high. It lived in the late Jurassic period and was distributed in Asia.
