Top 10 Most Powerful Prehistoric Animals

The Top Ten
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. Megalodon had more than 250 huge, razor-sharp teeth and its mouth was so huge that it could easily swallow a person. The fossils of its teeth were once thought to be the tongues of dragons or similar beasts. Megalodon was in the same shark group as today's great white shark, mako shark, and porbeagle shark. All of these species of sharks are big, fast, fierce hunters-just like their prehistoric relative.

Not only this predator's PSI is the probably the highest, it's just unbelievable that there's a giant version of the mega Great White

A bite force of 24,000PSI. Deadliest predator ever.

2 Giganotosaurus Giganotosaurus is a genus of theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 99.6 to 97 million years ago.

A bite force three times less than Tyrannosaurus's, claws, size and hunting in packs.

3 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.

I love spino, but he sure as hell isn't king of the dinosaurs. Just because Spinosaurus is the biggest theropod doesn’t mean it’s the strongest. Spinosaurus is adapted for eating fish and wasn’t an Apex Predator,if anything Carcharodontosaurus was actually the apex predator as it was better adapted for large dinosaurs.

4 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 5805 Kilograms).

Rex means "King" in Latin. But Spinosaurus was actually king of the dinosaurs. Why call Tyrannosaurus king of the dinosaurs when Spinosaurus is? By the way, Septic bite, bone crushing bite, size and hunting in packs.

At least T. rex had a bone crushing bite that was able to hunt large dinosaurs while Spinosaurus is a fish eater (I can’t believe I just said that, even tho I love spino, but I gotta face facts).

5 Carcharodontosaurus Carcharodontosaurus is a genus of carnivorous carcharodontosaurid dinosaurs that existed between 100 and 94 million years ago, during the Cenomanian stages of the mid-Cretaceous Period.
6 Livyatan
7 Barinasuchus
8 Saurophaganax

True King of the Jurassic.

9 Short-Faced Bear

10 Jaekelopterus Rhenaniae
The Contenders
11 Torvosaurus Torvosaurus is a genus of carnivorous megalosaurid theropod dinosaurs that lived approximately 153 to 148 million years ago during the later part of the Jurassic Period in what is now Colorado and Portugal.

Prince of the Jurassic.

12 Smilodon Smilodon was a saber-toothed cat from North and South America that lived 1.5 million to 10,000 years ago. It had a short tail, but very strong legs and paws for catching big prey. It was also 7.2 feet (2.2 meters) from nose to tail. Smilodon's two main front teeth were up to 12 inches (30 centimeters) long. They were very sharp, but quite thin. Smilodon probably used them to stab into its victim, or to slash its flesh and cause gaping wounds so the prey bled to death. Smilodon could open its mouth very wide, ready to strike its prey as though cutting it with a big knife. It may have gone for the throat-to cut the blood vessels and breathing tube.

Two words: Giant sabers.

13 Carnotaurus Carnotaurus, meaning "Meat eating Bull" in Ancient Greek, is a genus of abelisauridae theropod dinosaur that lived in what is now South America about 70 million years ago in the Late Cretaceous period.

Bite force, horns and size.

14 Allosaurus Allosaurus is a genus of large theropod dinosaur that lived 155 to 150 million years ago during the late Jurassic period.

Serrated teeth, big claws, speed and hunting in packs.

15 Helicoprion
16 Sarcosuchus
17 Mosasaur
18 Hatzegopteryx Hatzegopteryx is a genus of azhdarchid pterosaur found in the late Maastrichtian deposits of the Densuș Ciula Formation, an outcropping in Transylvania, Romania.
19 Deinosuchus Deinosuchus is an extinct genus related to the alligator that lived 80 to 73 million years ago, during the late Cretaceous period.
20 Kelenken
21 Acrocanthosaurus Acrocanthosaurus is a genus of theropod dinosaur that existed in what is now North America during the Aptian and early Albian stages of the Early Cretaceous.
22 Megalania
23 Ceratosaurus Ceratosaurus was a carnivorous theropod dinosaur in the Late Jurassic period (Kimmeridgian to Tithonian).

Oversized teeth used to rip flesh clean off the bone and horns used for piercing flesh.

24 Quetzalcoatlus Quetzalcoatlus is a pterosaur known from the Late Cretaceous period of North America (Maastrichtian stage), it was one of the largest known flying animals of all time.
