Top 10 Most Dangerous Dinosaurs

The Top Ten
1 Tyrannosaurus Tyrannosaurus, meaning "tyrant lizard", from the Ancient Greek tyrannos, "tyrant", and sauros, "lizard" is a genus of coelurosaurian theropod dinosaur. It also had a tremendous bite force, the strongest of any Dinosaur and living terrestrial animal. Its bite force reached up to 12,800 pounds (roughly... read more

T-Rex is awesome! He is the one, the only, king of all dinosaurs! There are some things Tyrannosaurus Rex has that Spinosaurus doesn't:

1. T-Rex has bone-crushing jaws that could crush a car.
2. He can run 25 miles per hour, faster than a person.
3. He lives in North America.
4. He has feathers.
5. He could prey on sauropods (mainly Alamosaurus), hadrosaurs, and other dinosaurs. He even fights Triceratops.
6. He lived after Spinosaurus.
7. He is the king of all dinosaurs.

And 8. He hunts in packs like lions.

Spinosaurus, on the other hand, only has these things:

1. He lives in Africa, not North America.
2. His jaws are not very strong, and his teeth are conical.
3. He mainly eats fish.
4. Lives near water.
5. Walks on all fours, and probably wasn't that fast.
6. His sail was fused to his backbone, so if he fell over on his side, he would break his back and die.

And 7. He went extinct because he couldn't compete very well with the other carnivores in his environment once the climate was changing.

2 Spinosaurus Spinosaurus is a genus of theropod dinosaur that lived in what now is North Africa, during the lower Albian to lower Cenomanian stages of the Cretaceous period, about 112 to 97 million years ago.

How is Spinosaurus on top? It was not an apex predator, so don't let Jurassic movies or that Monsters Resurrected episode fool you. In real life, it was highly adapted to hunting fish instead of land animals and was weirder-looking than in most media.

The biggest carnivore dinosaur so far, not to mention one of the most adapted. So many people are incorrect about T-Rex, saying it's the smartest and most adapted. T-Rex braincases were actually fairly small, and adapted? Not as much as Spinosaurus, which had a sail that "could" have been used to control its body temperature. Recent studies suggest it could be semi-aquatic, putting it up against prehistoric marine predators. Also, the scene in Jurassic Park III was very accurate. The T-Rex died not because of the bite wound on the neck, but because the Spinosaurus twisted and snapped the neck, paralyzing or killing it. T-Rex fanboys need to learn their places.

3 Giganotosaurus Giganotosaurus is a genus of theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 99.6 to 97 million years ago.

Giganotosaurus is very dangerous. It is 47 feet long, 18 feet tall, and also hunted in packs. Forget T. rex! Man, it eats the biggest dinosaurs!

It may not have been the biggest dinosaur, but it was either the 3rd or 2nd largest carnivore. This guy is 47 feet long, 18 feet tall, and it hunted in packs. Only something from The Lord himself could kill this beast. This guy should be number 1!

Giganotosaurus was the second biggest Theropod, I think, but far bigger than Carcharodontosaurus. It ate sauropods, and scientists even say they were strong and big enough to kill a full-grown Titanosaurus. P.S., it was also bigger than T. rex, and I also think they only vote because some of these dinosaurs were famous and familiar.

4 Utahraptor Utahraptor is a genus of theropod dinosaurs. It contains a single species, Utahraptor ostrommaysorum, which is the largest known member of the family Dromaeosauridae.

Pound for pound, Utahraptor was one of the deadliest killers ever, ranking even above T. Rex, if we're speaking literally, only falling behind its smaller cousins like Troodon and Velociraptor. However, what it lacks in skill and speed, it makes up for in size and power. 20 feet long and 8 feet tall, Utahraptor could kill a full-grown grizzly bear by using superior agility to its advantage. It was more than a match for much bigger dinosaurs, some of which they hunted alone, despite these dinosaurs being more than twice their size.

5 Allosaurus Allosaurus is a genus of large theropod dinosaur that lived 155 to 150 million years ago during the late Jurassic period.

Yeah, sure, Allosaurus may not be the biggest or the physically strongest dinosaur on this list, but anything of that size and speed would've been more of a menace to modern society and us as humans than most other dinosaurs. The fact that it might've hunted in packs of over 40 doesn't make it any better. Nothing of that size or power should be traveling in groups that big, and the fact that it does... well, that just makes it an absolute menace, now doesn't it?

Allosaurus is a theropod built for both power and speed. It's the most common predator of the Jurassic, and also the most successful. Allosaurus has three huge talons on its powerful arms. Even though its bite is not as strong as a Tyrannosaurus, it is still a very devastating weapon with shark-like teeth, and it can use its upper jaw like an axe. Allosaurus can be put at number 5, because a Utahraptor is no match for Allosaurus.

6 Carcharodontosaurus Carcharodontosaurus is a genus of carnivorous carcharodontosaurid dinosaurs that existed between 100 and 94 million years ago, during the Cenomanian stages of the mid-Cretaceous Period.

It had a slightly darker look compared to the T-Rex and other larger carnivores. It also had smaller arms, such as the T-Rex, although having bigger arms gave it the ability to move better and have slightly better balance. It existed in the mid-end Cretaceous period.

Carcharodontosaurus should be number 3, while T-rex should be 4. Shark-toothed lizard (that's the definition) had a more lethal bite than T-rex and could possibly run faster. The only thing it was not superior to T-rex in is its brain. Its brain was only half the size of T-rex's.

7 Velociraptor Velociraptor is a genus of dromaeosaurid theropod dinosaur that lived approximately 75 to 71 million years ago during the later part of the Cretaceous Period.

Velociraptor should be 3rd because they are intelligent, fast, and most of all, they can jump really high. They might be small and the size of a chicken or 6 feet tall, but it doesn't mean that they can't be the deadliest dinosaur.

The Velociraptor is very deadly and hunts in packs. Although they are actually pretty small, I agree, they are probably the smartest and most intelligent dinosaurs to ever walk the Earth.

I voted for Velociraptor because they hunt in packs to take down dinosaurs twice their size. Not to mention their speed and razor-sharp toe claws. So dangerous!

8 Ankylosaurus Ankylosaurus is a genus of armored dinosaur. Fossils of Ankylosaurus have been found in geological formations dating to the very end of the Cretaceous Period, between about 68–66 million years ago, in western North America, making it among the last of the non-avian dinosaurs.

The Ankylosaurus is vegetarian, but they are quite dangerous, large, and staggering. I think they don't have too much fear of carnivorous dinosaurs. Although it is not as big as a Brachiosaurus, it's one of the most dangerous vegetarian dinosaurs. Their appearance is somewhat terrifying, armed like tanks, and their temper doesn't seem to be good. A bad-tempered dinosaur is dangerous, and the more bad-tempered it is, the more dangerous it becomes.

Ankylosaurus should mean armored lizard as its back and tail are full of deadly armored plates. At the end of its tail was a thick tail club. A big predatory dinosaur like T-Rex would have been lucky to have survived if it got clubbed.

9 Saurophaganax

Think of an Allosaurus only bigger, nastier, and mightier. Saurophaganax is an Allosaurus on steroids. It's the grizzly bear of the Jurassic period, challenging Allosaurus, Edmarka, and Epanterias. It had huge claws and ferocious jaws. This should be in the top 4 or higher.

Saurophaganax is the Grizzly Bear of the Jurassic. He could hunt anything twice his size. He makes Allosaurus look like a coyote compared to this killer.

Congratulations! Your Allosaurus has evolved into Saurophaganax!

10 Mapusaurus Mapusaurus was a giant carnosaurian dinosaur from the early Late Cretaceous of what is now Argentina and possibly Chile.

Disregarding the fact that Mapusaurus was bigger than the T. rex, it was also a pack hunter, hunting in groups of 3-5. Though it's justified as Mapusaurus's primary diet consisted of what appears to be the largest land animal that ever existed.

It took down the biggest dinosaurs, like Argentinasaurus (may have misspelled that). It hunted in packs and also killed other carnivores. It was about 45 feet, bigger than a T. Rex. Definitely the most dangerous Dino.

This dino was 40 feet long, weighed 3 tons, hunted in packs, and had powerful legs and tail.

The Contenders
11 Deinonychus

This creature is stealthy, fast, and intelligent, which makes it a formidable predator. They hunt in packs, usually numbering 1-5. It has razor-sharp claws which they use for hunting. Its sharp claws dig into the skin like blades and can almost claw inwards 180 degrees.

Yeah, they made a mistake in the first Jurassic Park, and they accidentally identified the Velociraptor as a Deinonychus. Deinonychuses are actually the ones that are scaly, are smart, and have big claws.

I'd say raptors are the most dangerous dinosaurs out there. If any raptor was scaled up to the size of T-Rex, they've got the whole package: speed, brains, claws, teeth, and teamwork.

12 Megaraptor

It is 26 feet long and 200 pounds. It's a successful hunter and more dangerous than T. rex. Don't say anything until you know about it. I hope you will go with me. That's all.

Megaraptor and Megalodon are stronger than a Utah raptor, so why is Utah raptor 4th?

13 Tarbosaurus Tarbosaurus is a genus of tyrannosaurid theropod dinosaur that flourished in Asia about 70 million years ago, at the end of the Late Cretaceous Period.

The Tarbosaurus is the most powerful predator in Asia. It can kill an Albertosaurus and just to say, Spinosaurus just seems powerful because it killed the T. Rex in Jurassic Park 3. It's not really that powerful.

Tarbosaurus is the most dangerous dinosaur in Asia. That's because it's basically T. Rex junior. It can definitely defeat a Velociraptor or a Utahraptor. I believe it should be about top 5 or 7.

The Tarbosaurus was a powerful dinosaur in the late Jurassic and early Cretaceous periods. It didn't have too many crazy challenges, which might have put it a bit weaker, but it did face the Therizinosaurus. By the way, the Tarbosaurus would definitely defeat the Velociraptors.

14 Acrocanthosaurus Acrocanthosaurus is a genus of theropod dinosaur that existed in what is now North America during the Aptian and early Albian stages of the Early Cretaceous.

The Acrocanthosaurus is 40 feet long and was stronger, faster, and smarter than any carnivore. Capable of killing almost any dinosaur, Acrocanthosaurus should be number 1.

Acro is like 5 feet bigger than the largest T. Rex and had a high bite force.

15 Albertosaurus Albertosaurus is a genus of tyrannosaurid theropod dinosaurs that lived in western North America during the Late Cretaceous Period, about 70 million years ago.

A close cousin to the T. rex, it hunted in packs. It is part of the 'Tyrannosaur' family. Need I say more?

They say Albertosaurus is the predecessor and ancestor of the T. rex.

16 Troodon Troodon is a dubious genus of relatively small, bird-like dinosaurs known definitively from the Campanian age of the Cretaceous period. It includes at least one species, Troodon formosus, known from Montana.

While enormous theropods like T. Rex and Spinosaurus can certainly pose a threat, Troodon is like something from a nightmare. With disemboweling claws and superior intelligence, this killer is faster than any human. But the real threat comes from its size. Troodon was 5 feet tall, small for a dinosaur, but this means it could go into buildings and hunt you down in your own home. With large eyes and good hearing, it could catch you in the dead of night. Add the fact that they hunt in packs, and your survival chance is absolutely zero.

17 Mosasaurus

Many people don't count Mosasaurus as a dinosaur, but I do and always have. It's stronger than many, as anything that came near it would be swallowed whole!

It proved to be quite a threat in Jurassic World, eating the Dominus rex with one bite.

Mosasaurus was huge. And it was not a fish or a dinosaur but still a beast!

18 Stegosaurus Stegosaurus is a type of armored dinosaur. Their fossil bones have been found in rocks dated to the Late Jurassic period, between 155 and 150 million years ago, in the western United States and Portugal.

No one beats this Dino! It could individually kill packs of anything, including Tyrannosaurus!

Plates on its back and deadly spikes on its tail. It must be on the top ten.

19 Carnotaurus Carnotaurus, meaning "Meat eating Bull" in Ancient Greek, is a genus of abelisauridae theropod dinosaur that lived in what is now South America about 70 million years ago in the Late Cretaceous period.

I mean, literally, Carnotaurus was one big predator, but paleontologists still believe that the one specimen, which was Carnotaurus Sastrei, was a juvenile and it was 25 ft tall. Yeah, I mean it was one of the most dangerous predators in the southern hemisphere as it could run at a speed of 45 km per hour. And by the way, I'm a big fan of The Gaming Beaver, so I should call him 'Toast.'

Why wasn't this one on the list to start? Just look it up, and you will see. I mean, its name means "meat-eating bull," and it was bipedal, 25 feet long, and weighed a ton. Also, it most likely was not a scavenger like the Tyrannosaurus rex is thought to be.

20 Triceratops Triceratops is a genus of herbivorous ceratopsid dinosaur that first appeared during the late Maastrichtian stage of the late Cretaceous period, about 68 million years ago in what is now North America.

Triceratops lived in a very hostile environment during its time. While it had horns and a thick frill for very effective defense, it was a territorial dinosaur and one that wasn't easy prey for any predator.

Scientists have actually flat out stated that Triceratops is officially the most dangerous dinosaur ever. Look it up on the Discovery Channel.

It is actually the strongest. A T. rex cannot bite through its frill, so it must maneuver around it to get bites. All the Triceratops must do is charge straight at it. I think it could beat a T. rex 70% of the time. T. rex was most likely an ambush hunter.

21 Dromaeosaurus

Too small to kill a T. rex but at least it is smart, right?

22 Majungasaurus Majungasaurus is a genus of abelisaurid theropod dinosaur that lived in Madagascar from 70 to 66 million years ago, at the end of the Cretaceous Period. The genus contains a single species, Majungasaurus crenatissimus.

Majungasaurus and Majungatholus is the same. Majungasaurus should be higher than this. Its quite stocky and has a very thick skull dome which can be used to headbutt the flanks of its enemies. Its also big and has powerful jaws with powerful teeth. It also has a powerful tail that it can use as a bat to strike an enemy. Also it has a cannibalistic behaviour.

Majungatholus atopus was a meat-eating dinosaur, a theropod. It was at the top of the food chain in its locale. It probably ate sauropods, long-necked plant-eaters and other large dinosaurs. The name Majungatholus is derived from "Majunga," a district of Madagascar and "tholus," which means dome in Latin.

23 Dilophosaurus Dilophosaurus is a genus of theropod dinosaur. It contains a single known species, Dilophosaurus wetherilli, known from fossil remains found in the Kayenta formation of Arizona.

Dude, that dinosaur is a beast. It can spit out acid up to 20 feet. If that hit a dinosaur like Utahraptor, that would blind it, and Dilophosaurus could go for the kill. Plus, it's very fast and can jump high.

I don't know how it landed in 16th place! For me, it's more dangerous than any other dinosaur in the world, even the T-rex. It eats the Spinosaurus. I don't care if you laugh, but you must see how that thing looks. It appears even more terrifying than a Tyrannosaurus Rex. That dinosaur is a BEAST! Really.

It didn't have a neck frill and couldn't spit acid but was still a powerful predator.

24 Tyrannotitan

Comparable to Giganotosaurus and Carcharodontosaurus (and possibly larger), it was one of the South American monsters surrounded by large sauropods for food. Its teeth could slice and were somewhat more robust, like a Tyrannosaur. Gave sauropods nightmares and has a killer name too.

Bigger than Tyrannosaurus, powerful arms, related to Giganotosaurus, Mapusaurus, and Carcharodontosaurus.

25 Pachycephalosaurus

See this guy has a big bony dome which head but with other pachycephalosaurs and to scare off other carnivores and say top back OF!

It could easily take on a troodon or any other small dinosaurs due to its powerful skull
