What was the largest dinosaur and the longest dinosaur?

The largest dinosaur in the world.

The largest dinosaur we've found so far is the Epitosaurus, which was 39 to 52 meters long! Heights can reach up to 18 meters!! The weight reaches 130 tons!!

In other words, 2 to 3 vibrators stand together and line up from one gate to the other in the football field. And if such a heavy behemoth walks on the field, its huge feet will make the earth tremble every time it steps on the ground, just like **. This is the meaning of the name "Zhenlong".

Shock Dragon. The age of the earthquake dragon lived was about 162 million years ago to 136 million years ago in the late Jurassic period. Taxonomically, it belongs to the sauropods, sauropods, and diplodocids.

In addition to the Episosaurus, the dinosaurs of the sauropod suborder (commonly known as sauropods) with huge bodies living on the earth at that time included Diplodocus (26 meters long), Brontosaurus (21 meters long, weighing 25 tons), Supersaurus (42 meters long, shoulders and hips), Mamenxisaurus (22 meters long) and Brachiosaurus (25 meters long, weighing 30 50 tons) and so on.

These giant dinosaurs were plant-eating, with their tall bodies and long necks allowing them to eat the leaves of tall trees. Such a huge body must require a particularly large amount of food, but these dinosaurs all have a relatively small head and a small mouth, how can they meet such a large amount of food? Probably they just had to keep eating.

Scientists speculate that Mamenxisaurus spent 23 hours a day eating! This is probably the best in the world.

Think about how many leaves a Mamenxi dragon eats in 23 hours, and there are thousands of other Mamenxi dragons, and many more giant sauropods. It seems that at that time, the earth must have been densely planted, full of forests, and the natural environment was very superior, so that so many behemoths could live leisurely on the earth.

Now, we don't see such a large animal on land anymore, and the only thing that can compare to them is probably the blue whale that lives in the ocean. Female blue whales can grow to more than 30 meters and can weigh up to 200 tons.

The longest is the Argentinosaurus, which is 41 meters long and weighs 98 tons.

The largest is the **Dragon, which is 36 meters long and weighs 100 tons.

It's Spinosaurus. Spinosaurus (Latin name: spinosaurus, meaning spinosaurus), is a large theropod carnivorous dragon, of which the subspecies Spinosaurus aegypti is the largest known carnivorous, fish-eating dinosaur and theropod dinosaur, body length of 12 19 meters, sail height meters, rump height meters, average weight of about 4 tons, the largest individual conservative estimate of 18 tons.

It was a large carnivore that lived at the same time as the sharkodontosaur. The main survival is in Africa in the Late Cretaceous, about 144 million to 65 million years ago.

Spinosaurus has obvious long spines on its back, which are lengthened by the nerve spines of the vertebrae, up to a height of meters (the largest one), and the long spines are inferred to be connected before death, forming a huge sail-like object (however, a few scientists believe that these long spines are covered by muscle, forming a bulge or back, similar to the back of an American bison). For the sensitive air front function of this sail, it is likely that the functions include regulating body temperature, storing fat energy, dissipating heat, attracting the opposite sex, threatening opponents, attracting prey, etc.

The largest known dinosaur was equivalent in size to 40 elephants.

The Fragile Dicolacilosaurus is the largest recorded dinosaur in the world, measuring the size of 40 elephants. The fragile dinosaurus weighed much more than the blue whale, it was 35 meters long, and he was also closely related to Diplodocus. The fossil of the fragile dinosaurus was also discovered in 1877 and subsequently studied and restored by archaeologists to give us a glimpse of what it is today.

And his size is so huge, his neck is very common, and the fossils of his spine are very incomplete. But according to current research, he is indeed the largest dinosaur known in the world.

Causes of the extinction of the dinosaurs:

As for the reason for the extinction of the dinosaurs, modern science has not yet found the real cause. There are a variety of hypotheses, including climate change theory, meteorite impact theory, species struggle theory, continental drift theory, acid rain theory, etc.

65 million years ago, the Earth's temperature dropped dramatically, causing the atmosphere to drop in oxygen, making it impossible for dinosaurs to survive. It is also believed that dinosaurs were cold-blooded animals with no hair or warm organs, unable to adapt to the drop in the earth's temperature, and were frozen to death.

During the Cretaceous period, an asteroid hit the Earth, causing a ** and firestorm on the Earth. Tens of billions of tonnes of material were thrown into the atmosphere, blocking out the sun's rays and depriving many creatures, including dinosaurs.

At the end of the dinosaur era, the first small mammals appeared, which were rodent carnivores that probably fed on dinosaur eggs. Due to the lack of natural predators in this small animal, more and more of them eventually ate up the dinosaur eggs, leading to the extinction of the dinosaurs.

To date, the dragon is the largest dinosaur in the world. The length reaches 32-36 meters, the weight reaches 31-40 pinches, which appeared in the Late Jurassic.

Titanosaurus. Up to 100 meters.

The longest dinosaur is a thin plate, which I read in a book.

**The longest dinosaur in the world, should be more than 40 meters.

Lived about 1 year ago

3.6 billion years to 100 million years ago.

The Late Jurassic Episosaurus is what scientists have discovered so far.

The largest dinosaur in stature. The Earthquake Dragon is 39 in length

52 meters, height sometimes.

It will also reach 18 meters. The reason why scientists call it a tremor dragon is.

Because its body is too big, when it walks, the ground around it will vibrate violently like **.
