Top 10 Deadliest Prehistoric Animals

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

The Top Ten

1 Megalodon 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. ...read 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.

Um.. Hello, giant carnivorous shark. Have you ever seen a tooth from one of these guys? It's enormous, and designed to slice through flesh.

The size alone is scary.

2 Saber-Toothed Cat

Meow... the last thing Entelodont hear before their organs are clawed out on the floor.

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

Which saber tooth? smilodon populator,machairodus kabir and machairodus horribilis are the largest and heaviest cats that ever lived.Smilodon populator is the best cat that ever lived,the largest,the haviest,the strongest.And smilodon had no sexual dimorphism,what means females were as big as males.Saber toothed cats should be the first on the list.I hate when people compare american lions to smilodons.american lion was really really really sexually dimorphic,males a lot bigger than females.it means that female smilodon would easily defeat american lioness.even female S.fatalis would defeat american lionesses...and male smilodon would beat american lion,smilodon was more robust and also had huge forelimbs...The best animals that ever lived...their fangs were 30cm long in both males and females.if they were really social,group of 6 smilodons weighted 3 tones,enough to knock down everything they find.and many other fascinating things and facts about them.love them or not;just admit;they ...more

3 Titanoboa

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

Obviously the best thing to ever slither the earth

It could beat t rex I should be 2nd

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.

4 Spinosaurus 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.

This one is not all that deadly. It's a fish eater

The biggest baddest carnivore ever

I think spino should be the deadliest dinosaur. Look at those claws and teeth!

In the movie jurrasic part lll I agree spino defeat t-rex but the reality is t-rex will win it is third in the top 10 strongest bite force of animals first is megalodon n second is predator x t-rex one bit on the neck can kill any creature on land n in the movie t-rex bite spino n spino didn't die because that's just a movie t-rex can cursh a car in just one bite that to without too much force applied on its jaw rhen think how would it be when it apply many force t-rex can kill any animal on land even taitanoboa its just need one bite to kill some one n spino jaw is not that strong that's why he eats only fish

5 Andrewsarchus

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

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

Was one of the largest mammal predators of all time

Andrewsarchus needs to be the top

6 Woolly Mammoth

This guy was so powerful he could own most predators

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

7 Tyrannosaurus Tyrannosaurus Tyrannosaurus, meaning "tyrant lizard", from the Ancient Greek tyrannos, "tyrant", and sauros, "lizard" is a genus of coelurosaurian theropod dinosaur.

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

One big, bad dinosaur.

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

Best non marine predator and fighter.

8 Liopleurodon Liopleurodon

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

Predator X can't beat the megalodon!

9 Megatherium

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

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

10 Entelodont

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

STRONG FAST LEGENDARY POWERFU

The Contenders

11 Mosasaur
12 Arctodus

Speed bite force size strength

This had a bite force of 2500 pound per square inch

13 Deinotherium
14 Deinosuchus Deinosuchus

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

15 Cave Lion Cave Lion

Teeth claws stamina speed

It fought with short face bears and dire wolfs.

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

16 Hyaenodon

Super deadly giant beasts

One of the deadliest mammals ever to have lived

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

17 Sarcosuchus

He was the largest crocodile ever.

18 Megalania
19 Gigantopithecus
20 American Lion
