Is Seismosaurus really the largest dinosaur in the world?

Whenever people talk about the largest animals on land, dinosaurs usually come to mind. We can imagine what it would be like for humans and underwater animals in front of dinosaurs.

There are also different types of dinosaurs. For example, there are many types of pterosaurs that can fly in the air, and there are many types of ichthyosaurs that can swim in the water, not to mention the countless dinosaurs that live on land. So among so many types of dinosaurs, which one is the largest? Many archaeologists have difficulty judging their size because the skeletons are incomplete, with only leg bones and skulls remaining. One of the most famous dinosaurs in China, Mamenchisaurus. The neck is much longer than the tail, almost half the length of the body. It is 21 to 25 meters long and weighs 30 to 50 tons, which shows that it is very huge. However, Mamenchisaurus needs to eat a large amount of plant fruits every day to maintain the normal operation of such a huge body.

In addition, Diplodocus, a giant dinosaur in northwest North America, can reach a length of more than 30 meters. Its head and tail are longer, its neck is 7.5 meters long, and its tail is twice as long as the neck, about 13 to 14 meters. The torso is short and thin, so it is not very heavy. Although Diplodocus has a long neck, it cannot bend freely. Feeds on succulent plants.

Many paleontologists believe that the world's largest dinosaur was Seismosaurus because the earth shook when it walked. When its bones were discovered by archaeologists, they only had vertebrae, bone plates, ribs, etc., as well as other hypothetical bones, so Seismosaurus had an estimated body length of 32 to 36 meters and a weight of 31 to 40 tons. Due to its huge size, if a group of Seismosaurs walks in a row, the ground will shake like an earthquake, hence its name.

Some archaeologists believe that Dreadnoughtsaurus schlei was the largest dinosaur. It was a type of brontosaurus species and was also a herbivorous dinosaur that fed on plants. The weight of Dreadnoughts rex was seven times that of Tyrannosaurus rex. What is even more incredible is that when a 65-ton dinosaur died, its body was not fully developed.
