Top 10 Deadliest Prehistoric Animals

This includes animals that lived after the dinosaurs, not dinosaurs and megalodon. This list is awesome.

The Top Ten

Megalodon The megalodon is an extinct species of shark which was about 59 feet (18 meters) long and hunted in the seas until about 1.5 million years ago. It was similar to today's great white shark-but three times longer and 20 times heavier. more.

The Megalodon is a perfect example of a creature so deadly that it can kill you, and you'll die never knowing what hit you. The Megalodon was the God of the oceans that feasted on practically any creature. They have amazing sense of smell and vision. It could sink its enormous powerful teeth into nearly any creature it wanted to. All it would take is one bite and death would be near inevitable. At more than 50ft in length, it was the largest shark to ever live. It could swim fast, and the most ridiculous thing about it is its jaw power. Its teeth are already sharp enough, but what they're compacting jaw strength reaches over 18.2 metric tons (more than 40,000 lbs), a force strong enough to crush a whale skull effortlessly. Combined with the ridiculously enormous, sharp teeth, the Megalodon can kill nearly any creature almost immediately. The Megalodon; the most powerful giant beast to have ever lived.

Giant great white that would be the oceans top predator if it was alive today. It would eat anything, even blue whales would probably be on the list. It can grow to 60 feet PLUS- no one will ever know how big these animals actually got. An Entelodont thankfully didn't swim too much because if it did it would be chum for this shark.

Yes your right! It's the strongest prehistoric predator ever. But, it's also the strongest predator ever. I had first noticed it in the History TV18. It can kill many strong animals. It can grow upto 60 feet or more. It's teeth is 5-10 times larger than the great white shark's teeth. It's absolutely amazing.

Your serious, this is not 1? The biggest megalodon was the size of 2 whale sharks and was 20 meters long. Teeth half a foot long, this even ate early whales! Its also the biggest fish to ever live

Saber-Toothed Cat

How are sabre toothed cats in 2nd place the only thing they are good at is wrestling also there teeth are brittle and can't bite threw bone. Utahraptor would easily be able to kill sabre toothed cat I think they should be in 2nd placeor pliosaurus.

Why is Andrewsarchus ahead of the saber-toothed cat? I mean I understand the Megalodon, but the Andrewsarchus, really? The saber-toothed car ruled the ice-age!

If you think smilodon ( saber -toothed tiger) is bad, there is more deadly creatures like terror birds including titanis, and the hatzegopteryx, a huge pterosaur. Hatzegopteryx did not live with smilodon though.

Nah. If only you people watched ice age. They are very friendly creatures


Same size as a sarcosuchus could kill it, it can swim in waters, it could probably eat a saber tooth in one gulp and he is 40 feet long (12 metres) 400 pounds (181.437 kilo grams) I think he should be in 2 place

40 foot long constrictor. 400 pounds per square inch of pressure. Equivalent to being squished with the weight of 3 Eiffel Towers

Huge. Snake. This beast could eat a stinking school bus. Dunno why it would want to though. Don't look this up if you are afraid of snakes, though.

He weighs as much as 3 Eiffel Towrs, he don't won't non unless you got buns, it's the titanoboa!

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.

The Tyrannosaurus would easily defeat the Spinosaurus, many are denying this because the of the inaccurate movie Jurassic Park III.

Some might say its bigger so it will win, put yourself in a room with a Black Mamba, if you say well the Black Mamba is more powerful so obviously it will win your correct, so stfu about "its bigger so it will win"

The teeth of a Spinosaurus weren't made to tear off flesh, instead it was meant for fishing, meanwhile the teeth of an Tyrannosaurus were adapted for crushing bones and tearing off flesh.

Tyrannosaur bite force was between 7000 to 13000 PSI while the Spinosaurus was far less(I checked many sources but they were all different but less than a Tyrannosaurus)

The prey of the Spinosaurus were fish.

The Tyrannosaurus hunted far more dangerous dinosaurs such as the Ankylosaurs, Triceratops, and more.

If you still think the Spinosaurus would win, you are brainwashed by Jurassic Park III

Get this thing in first place... NOW! Here are some reasons the first3 shouldn't be there. #1: Megalodon was as big as a bus and had the deadliest bite force of all. It was so big, it was really slow! Plus, it only fed on whales, so it wasn't a huge threat to other marine animals. #2: Saber-Toothed Cat isn't even its real name! Smilodon wasn't even that big anyway. Its mouth didn't open wide enough to use its big fangs, either. #3: Titanoboa was a constrictor, not venomous, and predators to big could just step on it when it was wrapping itself around them. The Spinosaurus was the fastest of the first 4, and the biggest. This dinosaur could hunt in water as well as on land, so it could follow pretty much everything pretty much everywhere. The sail helped it to stay active and to stay at a good temperature.

Megalodon was killed by being to cold and it was easily replaced by basilosaurus, the Smilodon had a week jaw and was small compared to Spinosaurus, Titanoboa is good but one slice to the new would kill it and it was 11 feet shorter than spinosaurus's full length, spinosaurus could definitely kill all of them! (Except Megalodon, which would be a 50/50 chance in a fight) If you think "well it only eats fish" then you're wrong. It has been proven that it ate Hadrosaurs, Crocodiles, other carnivores, they even found the backbone of a Pterasaur in a Spinosaurus stomach! Plus, Spinosaurus had large thigh muscles for its legs, which means it could run faster and for longer than T.Rex!

Spinosaurus (MAY HAVE) eaten fish when it was alive but I learned from playing Lego jurassic world on my Xbox one that a fact about spinosaurus is "the shape of spinosaurus' skull allows it to eat fish out of the water, in the addition of hunting down smaller dinosaurs". See did you read that it hunts smaller dinosaurs so those of you who thought it ONLY ate fish but it ate DINOSAURS SMALLER then it self.

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 more.

Tyrannosaurus is strong, but he's nothing compared to the Megalodon.

Why is this not number one? Doesn't his name mean tyrant lizard king?

He's pretty awesome, but not nearly as strong as megalodon

Best non marine predator and fighter.

Woolly Mammoth

This guy was so powerful he could own most predators

Well try to go fight it yo self.

This dumbass mammal shouldn't even be on the list it was a slow ass elephant that got its ass stuck in tar pit for 90 percent of the population


Andrewsarchus could crush bone it should be in 1st place for strongest bite

Biggest predator that was mammalian, ever. It was related to sheep and looked like a warg.

Was one of the largest mammal predators of all time

Andrewsarchus needs to be the top

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 should definitely be 1 it was probably the biggest and most powerful preditor ever

Predator X can't beat the megalodon!

He should be 1

Liopleurodon was nearly 3 times the size of the " killer t rex" it could kill megalodon due to superior bite force maneuverability and non independence from salt water and the restriction of slowing down consistently wasting energy and the fact that Megalodon was wiped out because the ocean got colder while liopleurorodon overhunted the prey they had which in my opinon is a pretty bad-ass way to die


Why is the stupid shark the top sea predator? It's not even that big! Sure it could swallow you whole, but that's because of its mouth shape. Mosasaurus is faster an would intentionally swallow sharks whole!

The mosasaur can grow to 17m long and can kill sharks. I believe it is one of the deadiliest.

And over 36 teeth on each row

Can EASLEY mill #2 and namby even the meg


Okay first of all you science buff the giagantic sloth you call cool couldn't even run faster than a shamble and the fact that rearing on its back legs could cause pre -arthritis rendering those cool claws useless. Basically it was a large clawed horse

Nothing took him down since t-rex my favourite guy look at those claws on Google!

This thing is dead because us man...

The Contenders

Deinosuchus Deinosuchus is an extinct genus related to the alligator that lived 80 to 73 million years ago, during the late Cretaceous period.

2 times the length of todays largest crocodiles, at least 10 times the weight and a powerful jaw strength ripping through steel. It had razor sharp teeth and can outsmart anything that tries to take a drink in its lake. (including t. rex and spinosaurus. Just search sarcosuchus or dienosuchus vs. Spino and see who the winner is. A Deinosuchus bite is far more deadly than a T. rex. Getting bitten by this beast is equal to stabbing 250 sharp pieces of glass into yourself. Its that OP

I think that Deinosuchus is probably the second coolest thing that ever lived after Aegisuchus.

These animals eat large dinosaurs. ENOUGH SAID!



This had a bite force of 2500 pound per square inch

Speed bite force size strength

Arctodus or shot faced near was definitely the most fearsome predator of the Pleistocene epoch period

Short-faced bears.


This lizard was in essence, a 30 foot long monster that prowled the Australian Outback 40 000 years ago, and would truly have been your worst nightmare if you came across one. Even its name, translates into the latino meaning, "Ancient Giant Butcher/Ripper". It was made all of pure solid muscle, a rapacious demon with curved fangs possibly fostering deadly venom used to dispatch victims with a single bite. Even if the victim, typically a giant kangaroo Procoptodon or the wombat Diprotodon got away, they would soon fall to shock induced blood loss, and die later, leaving a tasty corpse for the monitor to find, a lot like today's Komodo Dragon. Even real dragon wyrms which breathed fire would have thought twice before coming across a reptile this size, if they lived in prehistoric Australia. However, as was the case with other reptiles, like a running Game Of Thrones sized real life lizard lion known as Quinkana Fortirostrum and its relative Pallimnarchus, and the serpent Wonambi ...more


They would be more higher and powerful in the list if they had there tusks facing the way elaphants ones do


Excuse me but how is this guy seventeenth?! He could easily kill a T.Rex

He was the largest crocodile ever.


One of the deadliest mammals ever to have lived

Could run 35 mph and had a jaw power at over 1000 PSI

Super deadly giant beasts

Love this animal


Awesome canines, awesome fighting skills, strongest mammilian bite force ever! 2.1 metres tall! Terminator pigs uber deadly!

Legendary. Seriously, a saber toothed cat had no chance. My favourite animal.

Could bite through a Buick

Excuse me, they can own a saber toothed cat any day, these are twice as big. smilidon... give me a break

Cave Lion

The cave lion ( American Lion) was the largest true feline ever to exist. Although Smilodon was slightly heavier, smilodon wasn't a true cat. If the cave lion existed today, it would be my favorite animal. It had a bite force of over 1600 psi( pounds per square- inch). It could grow up to 12 feet in length, 5 feet in height, and weigh over 930 lbs. It could withstand high pressure on its head. Its greatest competitor was the short- faced bear( arctodus simus) a very close cousin of the the modern- day spectacled bear. To learn more about the bear and the cave lion, you can watch : Jurassic Fight Club- Ice Age Monsters.

I think this was one of the biggest cats ever sorry if I'm wrong I pretty much only study smilodons

It fought with short face bears and dire wolfs.

Teeth claws stamina speed

Livyatan Melvillei

Livyatan was more powerful than megalodon. While it’s bite was less powerful a ram could stun the shark. The megalodon went extinct because whales got to big for it to handle. The megalodon was only 40 ft, not 75. It’s overrated because it’s a shark when whales are actually the most powerful aquatic animals.

The only predator that can take on Megalodon. With 13 inch teeth and massive bite.

Most Powerful sea creature ever. Better than Megalodon and smarter too

How in the world is this Livyatan 26th, now get this thing 2nd

American Lion
Short-Faced Bear

Biggest bear that ever lived

That's basically the arctodus.

Dire Wolf

How in the world is dire wolf stronger than Dunkleosteus


Slicing beak and claws speed and size


Dunkleosteus was one of the first super predators in my opinion. It lived in the Devonian. It was a twenty - foot fish that did not have teeth, but scary looking plates. It looks goofy, but yet scary.

Could kill t-rex with one bite. Also, Megolodon has the biggest teeth ever

It's bite force was absolutely insane!
