The Top Ten

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!
[Newest]It should because it beats T-Rex 60% of the time
More comments about Spinosaurus

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
[Newest]Bone-crushing teeth, hidden bacteria, and the arms were still packed with muscle.
More comments about Tyrannosaurus

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.
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
[Newest]The Giganotosaurus is the strongest dinosaur ever. it has a large skull with sharp teeth that can rip through almost anything!

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!
[Newest]Just because it is big does not mean it is the most lethal. All you need to survive a T-Rex is a corner. Raptors work in teams, are fast, very intelligent and have dangerous claws and teeth.

Megalodon should be number 1 because his bite is 18 tonnes, his size is 50 ft, he hunts killer giant whales and has very keen senses
You guys are wrong spinosaurus can beat this guy because its diet consists of fish right.
Megalodon... makes me sick... Seriously though, people need to look up their information, anyone who says Megalodon is over 55 feet in length need to read a book and not watch a fake documentary made for Shark Week. Sure, it had the strongest bite force of any predator (not counting planktivores), but that's really what most people know about it. A reasonable length for it is 35-50 feet, any larger and it'd have one of the smallest teeth to body ratios of any shark (think baby teeth on an adult). By no means would it be above Predator X. or Mosasaurus, those are ancient predators who reshaped their respective ecosystems due to their fierceness. Also, Megalodon isn't a dinosaur, I guess some people might consider a dinosaur 'something prehistoric, ' but I don't consider one celled bacteria dinosaurs.
[Newest]Megalodon is bite harder the T. rex?

Massive and smart enough to fight in packs.
It took down prey twice the size of tyrannosaurus 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
Smarter and faster plus more stealthy then t rex.
[Newest]They are the most smartest dinosaur, fastest and they work together well, they are like the people of dinosaur age
They are not the smartest dinosaur the smartest was the troodon

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.
[Newest]The best and strongest dino ever

8Predator X
Predator X is awesome! Its bite is 3 or 10 times stronger than a t rex
Its head is 2 times bigger than a t rexs skull its teeth were a foot long
Secular scientists call it the ultimate marine hunter
This was probably more powerful than the megalodon, scientists theorise that it had a similar brain to today's great whites, making it intelligent. I've seen documentary's of it snatching T-Rex and other carnivores off the shore. No competition in my opinion.
I may not know exactly what species this is but it pretty much references to lipleurodon, the largest carnivorous animal in history. the thing was a master of stealth and still 75 feet long
[Newest]Best thing in the world oh my god amazing!

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.
A six foot long monster
[Newest]Velociraptor's are smart, fast, and hunt in packs.

Its a big walking, breathing prehistoric tank!
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.
Ankylosaurus should mean armoured lizard as its back and tail are full of deadly armoured plates. At the end of its tail was a thick tail club. A big predatory dinosaur like T-Rex would haye been lucky to of survived if it gets clubbed.
[Newest]This dinosaur had a armored body

The Contenders

It was bigger than T REX
This Dino was 40 feet long, weighs 3 tons, hunted in packs and had powerful legs and tail

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.
[Newest]This dinosaur is amazing put it first

This guy is an Asian t rex and can beat ceratosaurus and daspletosaurus.
Tarbosaurus is the second biggest member of the tyrannosaur family which includes tyrannosaurus rex.
There teeth are razor sharp and can cut through 2 meters of skin
[Newest]Tarbosaurus Is My 2nd Favorite Only Beaten By Spinosaurus To Me

TriceraTops can kill Trexes, not many people know this but Maximus triceratops can run faster than Trex, and can injure or kill them, search it.
Triceratops has huge horns which can stab t rex to death

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
One word: overrated. Not 85 feet long, not 150 tons. It is not a dinosaur. It was 20 feet, and 2.5 tons.

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 on of the top predetors

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.
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.
It is big it is mean and it probily hunted in packs

A close cousin to the trex. Hunted in packs. Is part of the 'Tyrannosaur' family. Need I say more?
The t-Rex is onle 20 feet bigger and the Albertosaurus hunts in pacts and 4 of those vs a t-Rex or any other dinosaur a albertosaurus will win
Because that's my name

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
No one beats this Dino! It could individually kill packs of anything including tyrannosaurus!
Stegosaurus is my faverete herbivore dinosaur put him in 2nd

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.

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.
Sharp horn that charge at predators. It a plant-eater
It should be in the top 10 in 2nd in my opinion

22Australovenator (Banjo)
The Australovenator is Australia's top predator. Claws on its hand are the size of Deinonychus'. (toe sickles. )The size of Australovenator is probably the same size of Utahraptor. In a place not far from Winton, Queensland, Australia called Lark Quarry the Australovenator foot prints are preserved, proving it was ambushing smaller dinosaurs.
This dinosaur is scary it could kill me easily. It took down sauropods. It is faster, smarter and more dangerous than T-Rex which scavenges for meat. Australovenator should be on top instead of T-Rex. A scavenger should be down the bottom while a hunter like a Australovenator should be at the top.
This dinosaur is very deadly and should be on top of the list since it is faster, smarter and probably more stealthy and dangerous then T-Rex and it his about the same size as a Allosaurus.

Ceratosaurus is about 25 ft long, weighing in at around 3000 lbs. It had 3 boney ridge like horns, one along both of its eyes and one above its nose. Hunted in packs, but also was a solitary hunter. Stood 13 feet tall and had arms that were about 4-7 feet long that ended in 4 razer sharp, 2 inch claws. ITS ONE HECK OF A PREDATOR!
Sometimes, a Ceratosaurus is powerful enought to take down a sauropod up to 9 times heavier than Sue (The world's strongest known T. Rex) ALONE. Reasons:
1. Ceratosaurus has one of the strongest bite compared to it's body
2. Ceratosaurus's claws are also very deadly, having a giant arm over a meter long and long claws around a inch

In a fight with the larger Carnotaurus: The winner is Ceratosaurus. The Ceratosaurus has stronger bite, stronger claws and arms and it doesn't have any weaknesses while Carnotaurus's weakness is that it has a very weak neck so if a Ceratosaurus bit the neck of a carotaurus, the Carnotaurus would become really weak and get finished.

This thing could beat up everything else on the list in a snap! It should be first!


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

Kronosaurus Is Not A Dinosaur But Put It 4th I Will Give Someone A Cookie.
Kronosaurus is not a dinosaur
Sea Creatures 1. Kronosaurus 2. Liplurodon 3. Predator X 4. Megalodon 5. Elasmosaurus Note They Are Not Dinosaurs!

Megalania is 40 ft long and ate giant mammals
It is a 25 ft. If it was a live to day there will be no people in alstrlea
Megalania has this vakterya that that can kill any animal 10 times its size. it ate the first humans in the world its also said its maybe alive today on kamoto island

Screw all of you this one is the best


Probably the most dangorous Dino of all time it was a sixty foot long aquatic reptile that attacked virtually anything that moved and it traveled in packs of about 5 or 6.
Probably the most dangerous animal in the sea.
This monster was 50 foot long had razor
Sharp teeth and traveled in Packs.this monster
Could easily rip apart any animal it wanted to.

A Therizinosaurs can beat a tarbosaurs. Well an adult can
Therizinosaurs could beat the t-rex easily. Even though they still suck. Watch the movie dino king. Even though the T-rex wins its very sneaky.
Therisinosaurus should be in the top ten because it has huge 1m long claws that can easily kill a t rex or another theropods.


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

Gorgasaurus was very fast and hunted in groups so it was easy to take down a Pachyrhinosaurus


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

This din o can kill any dino if I was just to swim in the sea it can kill and dinosaur any time any where just try to beat this dinosaur try this dino think what can this dinosausr do and I t might still be alive


This creature is interesting. It is not a dinosaur, but a pterosaur. It was just like a Jurassic vampire bat. Not very big, it didn't have a beak. It had fangs. Sucking blood of huge dinosaurs. It looks like a vampire bat without ears



Was from the same family as allosaurus but was bigger and over all stronger

It was the biggest dinosaur and could have smacked any predator except Tyrannosaurus Rex to death.

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

Sarchosuchas was about 40ft long. It had really strong jaws and it could swallow a fully grown man. I think it was one of the most awesome dinosaurs in the world. It could probaly eat a T-rex if it had the chance.
Is the king of all crocs and has a bit as strong as the T. Rex


Deinosuchas was a huge prehistoric alligator. It had a really powerful jaw. It was a really fast swimmer. It could probably eat any dinosaur you could think of. It lived in lakes, rivers, and maybe bays. It was a really powerful dinosaur.

It should be in the top ten! He's the best! His name means man eating bull for crying out loud! He should be in about 9th place. In my opinion he is the best dinosaur by far!
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 scavanger like the tyrannosaurus rex is thought to be.
Whoa, why is he at 51? He should at least be at 12th place.


It could be bigger than spinosaurus.


It has a dangerous claw
It had a dangerous claw


A pterosaur, not a dinosaur.



Shunosaurus is the best since it has a tail club like Ankylosaurus. If a Gasosaurus tried to attack it would club it over the head. Shunosaurus lived in the Late Jurassic Period about 180-165 million years ago. It was the best of its time and ever out of the sauropods.

Deinocheirus, sichania, therizinosaurus, and spinosaurus are the bomb.


It was almost the biggest dinosaur and was 26m long and 4m tall at the hips


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.




Kentrosaurus is a African stegosaur. It has its back covered with plates like Stegosaurus and it has a tail covered with spikes. To a predator such as Allosaurus or Ceratosaurus that is pretty deadly.


We are adding one that isn't deadly


It's not even a dinosaur...

Seriously? Some of the dinos are on this list due only to misconceptions propagated by Jurassic Park (great movie, regardless) or outdated documentaries/FunFacts! And I feel that's unfair. Spinosaurus, like its smaller counterparts, Baryonyx and Suchomimus, likely was a coastal hunter. I can see the thing killing sharks, but not Tyrannosaurus. Yeah, it was bigger, but just because it got hyped up several years ago as the new T-Rex doesn't mean it in any way was some big dino hunting killing machine. The tyrannosaurids and charcharosontosaurids deserve the credit they get here, as do certain raptors, such as Deinonychus (classified as Velociraptor when Chrichton wrote the book, Jurassic Park, which led to an enormous misconception about the little Mongolian raptor) and Utahraptor. These specific raptors were awesome, but don't talk about Troodon (only on here for its intelligence, which was still insanely small by modern biological standards) and Velociraptor (famous for the misnamed Deinonychus in Spielberg's great but innacurate film). And then there's a bunch of non-dinos on the list, like Megalodon, Megalania, Predator X, Liopleurodon, etc. And Jeholopterus could NOT suck blood, that was an enormous hoax.

There is, however, a decent amount of evident which might suggest Sinornithosaurus, a raptor, was actually venomous. Yeah, I know, awesome. And even if this evidence has been misconstrued, which is still up to debate, it was a raptor that hunted in packs and could glide. The fact that the little sucker might have had a venomous bite added to these raptor attributes makes him my favorite dinosaur, ever.

Daemonosaurus was a pack hunter only a bit small but ultimately deadly. They followed an alpha like an leader. Daemonosaurus fighted for territory. Where ever the alpha went they went.
I think this dino should have been on number nine.

Its 48 feet long
How its look like
Can kill a t rex

It has giant claws that are about 9 inches long, and if that baryonyx gets on you that's the end of your life

It has speed and strength. Many twets too.


One of the most beutifull killers ever.


It's a dinosaur that looked like a female dog

This dinosaurs was like a Therizinosaurus. This dinosaurs is the probably the most powerful one.

Because it has a club on the back of it's tail
It had a bony club on it's tail



Although not a dinosaur, it was more dangerous than any other pterosaur. Including quetzalcoatlus. This animal ate sauropod dinosaurs! I bet it could kill a quetzalcoatlus with ease.


Wolf-like dinosaur. Name means "Wolf-face".

How its look like
Amphicoelias is the largest creature to ever live on earth. It was nearly 60m in length, about 196 feet, making the Blue Whale look like a midget. It defended it's self by sheer size, and the fact that they were in herds.
Amphicoalias is a herbivore and not a carnivore.
It was 200 ft and weighed 90 - 120 tons it could kill a trex, an allosaurus and a giganotosaurus combined. And it had a whip like tail that could decapitate a tarbosaurus. It could squish a ceratosaurus or a ausrtaloventor as if it were a bug.


Neovenator is related to the Allosaurus of North America, but it was more lightly-built.

Diplodocus beat big al two he smashed big al two into the rib cage diplodocus is a champion in fighting only the smartest raptor beat diplodocus diplodocus massive diplodocus survive without water for weeks diplodocus should be first!
This is my favorite herbovore

That's ridiculous for putting brachiosaurus in last place
That ridiculous putting Brachiosaurus in last place
This dino is my favorite herbivore
