Top 10 Most Dangerous Dinosaurs

The Top Ten

1 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.

Putting T-Rex in 1st place is ridiculous. T-Rex had tiny arms, so the only way they were able to catch prey was with their teeth. Scientist have thought that T-Rex was a scavenger because of that.

Spinosarus was the biggest of all the meat eating dinosaurs and it was also the deadliest. And the second biggest one, Carcharodontosaurus is missing from this list.

Spinosaurus is the biggest of all carnivorous dinosaur. It weighed about 3 buses. Spinosaurus is a fish eater sometimes eat meat.

It was bigger than all of the other dinosaurs on this list. The only reason why Utahraptors could bet it is because they hunt in packs. And Megalodons were fish not dinosaurs!

Spinosaurus is the strongest dinosaur in the whole universe. It could easily kill that stupid tiny weak trex. Spinosaurus was 18 metres (60 ft) long and 7 (23 ft) metres tall. Trex was only 3 (10 ft) metres tall and 10 (30 ft)metres long. Spinosaurus was so powerful it could kill every single other dinosaur that ever lived- including stupid trex! Trex was so weak it couldn't even run let alone walk fast.
LONG LIVE SPINOSAURUS THE KING OF ALL DINOSAURS!
STUPID TREX DIED OUT BILLIONS OF YEARS AGO BECAUSE IT COULDN'T HUNT!

2 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.

I think T-Rex hast to be the best. Its probably bin the best known dinosaur out of the whole world.

Dude about 82% of his diet had armor, horns and could run way faster then him not including sauropods.

the most strongest dinosaur in the universe, The King Of Tyrant Lizards: "Tyrannosaurus Rex". What a materpiece it was in his time... If we compare with Spinosaurus, that dino is nothing in front of T-Rex but when we talk about Giganotosaurus there is a 50:50 or can be stronger or the same. But others don't come in the league...

Strongest dino jaws, muscular, pretty smart, and deadly as hell

Dude, I went to so many websites, watched many videos and read many books and after all my findings, I don't think, I KNOW that Tyrannosaurus is the deadliest dinosaur that ever lived.

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 a giant carnivore in South America. This killer weighs 7 tonnes and lengths about 48 feet

It's larger than a T-rex, fiercer than a Spinosaurus, and ate sauropods, unlike the others mentioned which ate small prey.

Actually, Spinosaurus was fiercer. Spinny has been dubbed the "world's most dangerous dinosaur". - RedTheGremlin

It is a 43 feet beast and 13tons in weight. It can take down a full grown argentinosour. I think it is the real king of all dinosaor

Comment three says "Spinny has been dubbed the "the worlds most dangerous dinosaur".
Spinny?

Giga Rules

4 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.

Had a slightly darker look compare to the T-Rex and other bigger 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.

Interesting reptile. Similar in fact longer than the Tyrannosaurus. Was commonly found in the North Africa and South American region.

He has the most unique bite "the hatchet bite" from all dinosaurs.

If a dinosaur has the hardest name to spell
It is the most dangerous one.

5 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.

Very lethal. This dinosaur is actually more comparable to the raptors in Jurassic Park. This is a killing machine.

You just can't be unafraid of those claws.

This guy is ' nuts! He weighs almost a ton, he's 18 feet long, he's got 15 inch sickle claws on each foot, he's like a huge velociraptor, he's UtahRAPTOR!

Think of the Jurassic park Raptors the size of an allosaurus

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

Massive and smart enough to fight in packs.
It took down prey twice the size of tyrannosaurus rex

Smarter and faster plus more stealthy then t rex.

I think the allosaurus is dangerous from the speed of one and it's jaws and when they fight they roar louder then they do when there standing

Allosaurus is a smart, fast and lethal predator. I think he should over top T-rex. This dinosaur should be number 1!
And please put Utahraptor below Al.

P. S I'm a Allosaurus fan.

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.

A dinosaur with a pair of huge sickle claws on each foot

Everybody knows these things can open doors and when coupled with the fact that they are all Jehovah's witnesses it can get pretty scary. When I was out in the jungle I caught one staring at me... I could tell she was thinking and working things out... So I ran into my hut and the next thing I know, the door handle moves and the door swings open! The raptor just stood there and said "Have you found Jesus"? I haven't stopped screaming since.

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

yes one of the fastest dinosaurs and it can open doors name a dinosaur that's cooler plus it's my favourite.

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.

Its a big walking, breathing prehistoric tank!

Ankylosaurus had low intelligence and poor eyesight but the reason it is so powerful is because of its armor. It must be flipped over just to be injured.

Predators needed to flip it over to kill it, it just needed to swing its tail.

Have you guys seen how powerful this guy is withe his clubed tail he can wack a t rex's leg and the t rex would be left in mercy of other dinosaurs.

9 Saurophaganax

One of the biggest and strongest carnivores in the world has to be in the top ten it is also the same size as the mighty tyrannosaurus rex so guys look out for this dinosaur because it is extreme

Its even bigger and deadlier than Allosaurus

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 Liopleurodon Liopleurodon is a genus of large, carnivorous marine reptile belonging to the Pliosauroidea, a clade of short-necked plesiosaurs. The two species of Liopleurodon lived during the Callovian stage of the Middle Jurassic Period.

Liopleurodon is the biggest carnivorous animal ever to lived on the earth. It weighed 6 times bigger than T. Rex and lengths about 95 feet long. Each of its flippers were 10 feet long. It have teeth longer than a sword.

Why is this Dino not in the top ten it is so dangerous

It is probably the largest dinosaur event hough it kind of isn't because it lives in the sea

This one for sure is the deadliest sea reptile in the world it should be higher than this.

The Contenders

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

This Dino was 40 feet long, weighs 3 tons, hunted in packs and had powerful legs and tail

It was bigger than T REX

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

How the heck do u know? So, this animal looks scary does not mean its dangerous!

12 Deinonychus

This is the critter passed off as a Velociraptor in Jurasic Park, 150 lbs fast and inteligent and hunting packs. And that sickle front tow nail. Velociraptors were only about 6 ft long and weighed less than 70 lbs.

Two words, JURASSIC and PARK

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

These were fast, agile raptors with large wicked claws that are at least 4 inches long. They also hunted in packs, making them more dangerous.

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.

It's lower than weaker dinosaurs, more peaceful dinosaurs, some non dinosaurs!

This guy is an Asian t rex and can beat ceratosaurus and daspletosaurus.

Most of these I don't even know why do they put theme in there if only 4 maybe 5% of people are going to know what it is and most of these are very VERY smart extinction is a good thing today!

Tarbosaurus is the second biggest member of the tyrannosaur family which includes tyrannosaurus rex.

14 Megaraptor

It is 26 feet long and 200 pounds. It 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 was 20 to 35 feet long it was the of the raptor family it could take down a dilophosaurus

Megaraptor and megalodon is stronger then a Utah raptor so why is Utah raptor 4th

Megaraptor can't even kill one Velociraptor

15 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.

They layed eggs in their prey once they killed it to keep it warm and give it a food supply once it hatches, so yeah, there were quite dangerous and smart.

Some say their teeth were silver and as painful as bullets, they're nocturnal eyes would slowly poke out of bushes at night before you face your demise.

I just love it. Smart. Fast. Just like me. Just right for me.

Smart. But sometimes I wonder why most dinosaurs weren't very smart.

Smart. Toe Claw. Fast. Enough said.

16 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, Acrocantho saurus should be number 1

It Is The Second Largest Carnivore In North America It Weighs 5.5 Tons And Is 39 Feet Long!

Kill with no problem

Never heard of it

17 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.

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

Because that's my name

A close cousin to the trex. Hunted in packs. Is part of the 'Tyrannosaur' family. Need I say more?

My name is Albert.

18 Torvosaurus Torvosaurus is a genus of carnivorous megalosaurid theropod dinosaurs that lived approximately 153 to 148 million years ago during the later part of the Jurassic Period in what is now Colorado and Portugal.

This is an extremely dangerous dinosaur. It should be on top of the list. A Torvosaurus could kill a Allosaurus. It probably could take down gigantic dinosaurs like Dimerosaurus. (A Portuguese sauropod) It would have killed other predators like Allosaurus or Ornitholestes.

This dinosaur needs some more attention. Maybe this top ten is a fanboy theory,because why is torvosaurus listed down? This is a strong and powerful dinosaur. It's maybe shown with slender pictures but ones you saw it's skeleton...you will see this one is a monster. Others should vote for this.

Torvosaurus is smaller and dumber than the top 3

It should be in the top 10 in 2nd in my opinion

19 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.

Come on it can kill a t-rex with the spikes and scales

even two allosaurs can't kill a stegosaur but a herd of stegasaurs even 5 allousaurs can't beat

It's plates were full of blood vessels and wouldn't be potent whatsoever in battle.

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

The plates would not be of any use in battle they were just soft - RewMac0435

Walnut-sized brain

20 Vastatosaurus Rex

We can defeat it if we were big enough

I like them all

Nicer than a t rex

This is not a real Dinosaur 🦖 it is way more powerful than any single Dino on this list

21 Dromaeosaurus

Too small to kill t rex but at least it is smart, right?

I think it could not harm a huge T rex may have formed packs over small ceratopsians like leptoceratops

22 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 beast it can spit out acid up to 20 feet if that hit a dinosaur like Uthahraptor that would blind it and Dilophosaurus could go for the kill plus its very fast and jump high.

Even though it most likely didn't have poison and a frill, it was a LOT bigger than you see it in Jurassic Park and dangerous

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

FAKE! JURASSIC PARK SAYS IT HAS ACID AND HAS A NECK FRILL! But it being a theropod, speed highjumps and the head crests are true.

23 Tyrannotitan

I like the tyrannotitan

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

Should be 2

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

24 Pachycelaphosaurus

It have powerful skull it can hit with head!

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

My fave dino of all time this beast could beat most dinos or at least seriously wound

25 Kronosaurus

Kronosaurus Is Not A Dinosaur But Put It 4th I Will Give Someone A Cookie.

Give me I want a cookie

Kronosaurus is not a dinosaur

This is the coolest dino
