Top 10 Most Dangerous Dinosaurs

The Top TenXW


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 should be the tyrant lizard king not t rex

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

It can only run at 19 mph which is slower than a human in a life or death situation, its arms are useless and all you need is a corner and you are safe. At most it should be number 3-5.

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

So big it can step on you

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!

This thing has 9-15 inch claws and makes the Velociraptor and Deinonychus look like a Turkey. This could rip a lion to shreds without so much as a scratch. It is the ultimate killing machine. Highly lethal. This is deadlier than the raptors from Jurassic Park. If they were still alive we would be tasty snacks and they would be the dominant species.

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.

Spinosaurus is best but carcharodontosaurus is the second biggest meat eater so it should be second.

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.

Not even a dinosaur!

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 so awesome it should be first

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

It is as small as a chicken it is not strong

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

It was bigger than T REX

Sauropod slayer


Its a big walking, breathing prehistoric tank!

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.

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.

Not a dinosaur

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.

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.

Walnut-sized brain

You are right and I mean it

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

Hunted Sauroposeidon, the tallest dinosaur



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

Smart. Toe Claw. Fast. Enough said.

As smart as a possum, it is very smart for a dinosaur.

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

# 18 giant squid

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

V7 Comments

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.

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

Sharp horn that charge at predators. It a plant-eater


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.

Your right but not better than spinosaurus and carcharadontosaurus
