5. Armored fish Dunkleosteus

Armored fish Dunkleosteus

Dunkleosteus is the largest fish in prehistoric times. Its head and chest are covered with bone-like plates. Instead of teeth, these fish possess two sharp bones, forming a bird-like structure.

Dunkleosteus is capable of attacking with its armored jaws strong enough to tear apart prey that also has armored leather like me. They are dubbed the " ocean nightmare" for all prehistoric marine animals.

This fish shows that they are up to 10 m long and weigh about 4 tons.

6. Super shark Megalodon

Megalodon super sharks have bodies up to 30 m long and weigh more than 100 tons. They were dubbed the most ferocious assassin in Earth's history with enough bites to crush a car.

According to scientists, Carcharodon Megalodon can be 15.9-20.3 m long and weighs 47-103 tons.

The size between today's white shark and Megalodon shark.

The giant super shark lives in the prehistoric period of the late Oligocene and Neogene period about 28-1.5 million years ago.

7. Huge Piranha fish

Giant Piranha fish

This fish lives 8-10 million years ago and is 1 meter long, 3 times larger than modern piranhas today.

8. Giant crocodile

With a total body length of up to 13m, weighing nearly 10 tons, Purussaurus is the largest and most ferocious crocodile in Earth's history.

Titanoboa (giant python) is a snake genus that lived about 60 to 58 million years ago, in Paleocene.

The researchers estimated that T. cerrejonensis is about 13m long, weighs about 1,135 kg and is about 1 meter wide at its thickest point.
