The Deadliest Dinosaurs of All Time – Watch out!

On the 22nd of June, the movie “Jurassic World: Fallen Kingdom” will start showing in cinemas. As a dinosaur enthusiast, I’m sure that you cannot wait for this day. As you prepare yourself for this day, why not familiarize yourself with some of the most dangerous dinosaurs to ever exist?

Even though dinosaurs are known to be dangerous, there are some species which are considered to have been more dangerous than others. In no particular order, below is a list of ten of the most dangerous dinosaurs that existed.

1. The Tyrant Llizard

Tyrannosaurus, also known as the ‘tyrant lizard’ had a bite force that was so tremendous that it was considered to be the strongest among all dinosaurs and all the living terrestrial animals. Its bite force could reach up to 5,805 Kilograms. It had a mass of 5,800 – 15,000 kg and was about 4.6 – 6.1 m tall, half as tall as a telephone pole.

Considered to be the largest land-living carnivore of all time, Tyrannosaurus was capable of delivering bites that could crush stones. Its most massive tooth had a length of about 12 inches. It fed on plant-eating dinosaurs.

2. The Should be the ‘King of Dinosaurs’

Spinosaurus aegyptiacus is considered as one of the largest carnivorous dinosaurs ever to live. This dinosaur can swim, and measured over 50 feet long, almost as tall as a three-story building. The Spinosaurus is one of the few dinosaurs with the ability to swim. It was so huge that many dinosaur lovers believe that it rivaled the tyrant lizard, commonly known as, Tyrannosaurus Rex or T Rex. It’s also referred to as the ‘spiny lizard’ because of the large spined sail which ran down its back. This huge dinosaur’s weight was about 7.4 tonnes, and its length was 46 feet.

It had an elongated skull and jaws that resembled those of a crocodile that was about 5 feet long.

3. The Toothy Masiakasaurus Knopfleri

This one was so dangerous that there is no other predator dinosaur with the kind of teeth that this dinosaur possessed. It had front teeth which were projecting forward, and it is these teeth that it could use when slicing and then cut its captives into chunks that were chewy by using its rears that looked like blades.

Also known as a vicious lizard, this dinosaur with 6 feet body length, is believed to have feasted on lizards, fish and other critters about 65 – 70 million years ago in Madagascar, an island nation of Africa. It had a long neck and tail which made up most of its length.

4. Gryposaurus monumentensis/ the Hooked Beak Lizard

(Pronunciation: GRIP-oh-SORE-us MAHN-you-men-TEN-siss) This was a big-boned and duck-billed dinosaur that could have eaten any vegetation it stumbled across. It had a massive skull that was able to pack over 300 teeth that it used for cutting up fibrous greens. In addition to the 300 teeth, it had hundreds of more teeth for a replacement that rested on its jawbone for use anytime they were required.

It lived about 75 million years ago in the Late Cretaceous. This plant-eating dinosaur may have been about 30 feet long as a fully grown dinosaur and had a head that was 3-foot long, almost as big as T Rex.

5. Allosaurus / Different Lizard

These existed about 155 million years ago. Its name translates to ‘different lizard.’ They are alleged to have had an enormous skull with numerous sharp teeth. They were 9 meters long although some studies suggest that they were about 12 meters long. They possessed a massive tail which offered great balance. They are said to have weighed 2.3 metric tons. Just imagine what would happen if they could come alive.

This massive carnivore found in Utah, weighed over 1,500 kilograms in its adulthood, with a height of 4.5 – 5 meters.

6. Troodon – Hunt in Packs

Although small in size, these dinosaurs are considered to have been very dangerous. This is because they could hunt in packs and they were also blessed with very large eyes which made it possible for them to hunt in the dark at night. It only weighed about 150 pounds, but trust me, a group of five of them was equivalent regarding danger, to one hungry and full grown T Rex. What made this dinosaur different from the rest was the size of its brain.

Compared to the other carnivorous dinosaurs that lived in the Late Cretaceous North America, Troodon had a relatively big brain.

7. Majungasaurus / Cannibal Dinosaur

Previously known as Majungatholus, this dinosaur was given the name, ‘cannibal dinosaur’ by the media. They dubbed them cannibals because it is said that they preyed on the others of their kind when hunger pangs were too much to bear. There were tooth marks that were found on some of their bones which were tooth marks from the same species.

They weighed about one ton, and they are alleged to have spent most their time terrorizing the smaller plant-eating dinosaurs that were found in late Cretaceous Africa.

8. Utahraptor – The Slasher

No raptor was as dangerous as the Utahraptor. This raptor weighed about a ton and lived approximately 125 million years ago, way before their descendants; the deinonychus and velociraptor. It had single claws that were curved. It had claws on its hind feet that were almost a foot long. These claws were used for slashing and disemboweling their prey.

Discovered in Utah in 1991, these raptors were almost entirely covered in feathers. It weighed over a ton and was 25 feet long. This means that it was and three car links long and could run speeds of up to 20 miles per hour. According to its weight, it was ten times heavier than the average raptor.

9. Giganotosaurus – One of the Biggest

This dinosaur found in South America was enormous. It weighed about eight to ten tons. Can you imagine? It had three fingers and is considered to be among the biggest dinosaurs to ever walk on the earth. It was one of the theropods that were capable of taking down a titanosaur that was fully grown or even a more manageable juvenile. It was larger than T Rex or Spinosaurus.

An adult Giganotosaurus had a mass of 8,000 kilograms and a length of about 12 – 14 meters. It had a speed of 50 km/h.

10. Liopleurodon – The Swimmer

These are another species of dinosaurs that were able to swim. In fact, they were excellent swimmers because they had four strong limbs. They were capable of growing to an enormous length of 25 meters. They are believed to have existed in France and England. One of these species is alleged to have existed in Russia also.

The structure of their body provided them with excellent acceleration and top speed. It weighed between 1,000 – 1,700 kg. It lived between 166.1 and 139.8 million years ago.
