Top 10 Deadliest Prehistoric Animals

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

The Top Ten Deadliest Prehistoric Animals

1 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.

I hope this not real that will be very scary to swim in the ocean with this
in the waters today.

This is the biggest shark ever that ever existing this is the best on ever

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.

2 Saber-Toothed Cat

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

Diego in ice age - Ajkloth

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

These cats would kill anything that comes near them

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

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

It could beat t rex I should be 2nd

4 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 - Apoc

Excuse me why is Sabertooth higher than any dinosaur
Also Spino is amazing

I was gonna chose megalodon, but Spinosaurus is my favorite dinosaur. - TerryThebestsoccerplayer

How is Smilodon more powerful than it? It could squish it without knowing!

5 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.

It has the strongest bite force any animal on earth,it's smart,and it's fast

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

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

Well try to go fight it yo self.

7 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

8 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 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

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

9 Mosasaur

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!

And over 36 teeth on each row

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

Can EASLEY mill #2 and namby even the meg

10 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

This thing is dead because us man...

The Contenders

11 Arctodus

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

Speed bite force size strength

This had a bite force of 2500 pound per square inch

Short-faced bears. - PhoenixAura81

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

These animals eat large dinosaurs. ENOUGH SAID! - PhoenixAura81

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

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


13 Megalania

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

14 Deinotherium

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

15 Sarcosuchus

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

He was the largest crocodile ever.

16 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

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

17 Hyaenodon

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

18 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

19 Gigantopithecus
20 Livyatan Melvillei

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

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.

21 American Lion
22 Short-Faced Bear

Biggest bear that ever lived

That's basically the arctodus. - PhoenixAura81

23 Gastornis

Slicing beak and claws speed and size

24 Dire Wolf

How in the world is dire wolf stronger than Dunkleosteus

25 Dunkleosteus

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.

It's bite force was absolutely insane! - killerqueen1010

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

26 Sarkastodon

It is hyaenodon far relative

27 Indricotherium

It can trample predators

28 Hatzegopteryx Hatzegopteryx is a genus of azhdarchid pterosaur found in the late Maastrichtian deposits of the Densuș Ciula Formation, an outcropping in Transylvania, Romania.

Oh man. I think it is scarier than Quetzalcoatlus. Due to having a robust skull twice as wide as Quetzalcoatlus.

29 Phorusrhacos
30 Basilosaurus

It was the largest whale that ever lived and was a killer so it deserves to be on this list

31 Pterodactyl


32 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.

They are worse than a t-rex the hunt in groups and kill there prey easily

33 Anomalocaris

While they may not seem like much, their mouths could do some serious damage to the hard exoskeletons of most creatures in the cambrian

34 Thylacoleo
35 Sea Scorpion (Eurypterid)

A great Devonian predator that nobody has heard of. It looks really cool, though. Google it! - SigmaV84

36 Helicoprion

Not only a good predator but it had unique saw shaped lower jaw making it easy to shred prey. It's "whorlteeth" was probably it's most notable feature.

This creature looks like a shark except it has a buzzsaw-like mouth. - PhoenixAura81

37 Mosasaurus

Hello this thing is terrifying it should be1

Big and strong and eats dinosaurs easily. Lockey

38 Orthocone

These cephlapods were big carnivores and ate sea scorpions and other marine arthropods. They were huge as hell too!

39 Megistotherium
40 Bear-dog (Amphicyon)

The power and grappling dexterity of a bear, the aggression and jaws of a wolf, the agility and body shape of a lion. This predator was bigger than sabre-tooth, more maneuverable than the short faced bear and out-competed Entelodont and Hyaenodon to extinction!

41 Arctotherium

Another short-faced bear species. Lived in South America and was as tall as a grown man. - PhoenixAura81

42 Elasmotherium
43 Argentavis
44 Kelenken
45 Dinofelis

Let me guess, it's a very large prehistoric feline. Or a feline with reptilian traits.
Reality: It IS a feline, just not dinosaur sized and had no reptilian traits. Just related to smilodons (saber-toothed tiger). - PhoenixAura81

Preyed on, our early ancestors

46 Phorusrhacidae
47 Dimetrodon

It may look like a big lizard, but it's actually a proto mammal.

48 Epicyon

Epicyon was a very large dog

49 Aegisuchus

Competitor for the biggest crocodile and in my opinion not much people know him

50 Purussaurus An alligator is a crocodilian in the genus Alligator of the family Alligatoridae. The two living species are the American alligator and the Chinese alligator. Additionally, several extinct species of alligator are known from fossil remains.
