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.

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

What ankitha looks like when she looks at cauis

Surely the king of the sea

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.

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 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.

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!

I think this is better than titanoboa and smilodon, Smilodon isn't even dat big and they had to be in packs, spinosaurus was a one man army.

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.

4 Titanoboa

If it can meet megalodon,it will crush him!

He should be #2
he wayyy too powerful to be #3

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

5 Tyrannosaurus 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 ...read 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

Well try to go fight it yo self.

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 Mosasaur

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.

8 Andrewsarchus

The Andrewsarchus and Mesonychid look VERY similar. - PhoenixAura81

It’s dangerous because it is like a Saber toothed tiger
? - Carly19781

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

9 Liopleurodon 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.

He should be 1

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

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!

10 Megatherium

This thing is dead because us man...

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

The Contenders

11 Dire Wolf

How in the world is dire wolf stronger than Dunkleosteus

12 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

13 Arctodus

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

Short-faced bears. - PhoenixAura81

Speed bite force size strength

This had a bite force of 2500 pound per square inch

14 Deinotherium

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

15 Deinosuchus 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

IT IS CHOMPING A TYRANNOSAURUS REX! POOR T-REX!

16 Hyaenodon

Love this animal

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

17 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

18 Pterodactyl Pterodactyl
19 Megalania
20 Sarcosuchus

He was the largest crocodile ever.

21 Gigantopithecus
22 American Lion
23 Helicoprion

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

24 Gastornis

Slicing beak and claws speed and size

25 Short-Faced Bear

That's basically the arctodus. - PhoenixAura81

Biggest bear that ever lived

26 Livyatan Melvillei

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

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

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

27 Velociraptor 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

28 Sarkastodon

It is hyaenodon far relative

29 Indricotherium

It can trample predators

30 Dunkleosteus

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

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

31 Phorusrhacos
32 Hatzegopteryx 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.

33 Anomalocaris 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 Phorusrhacidae
36 Basilosaurus

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

37 Mosasaurus 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 Dimetrodon

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

47 Epicyon

Epicyon was a very large dog

48 Aegisuchus

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

49 Sea Scorpion (Eurypterid)

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

50 Purussaurus 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.
