First, a single-celled organism in the ocean evolved into a fish, then the fish evolved limbs and became an amphibian. The amphibian gradually evolved into a reptile by losing its gills.

Later, in order to gradually adapt to life on land, they evolved into dinosaurs.

The first named dinosaur, Megalodon, was a large carnivorous dinosaur with huge, serrated teeth that were fixed in the jaws with long roots. The tops of the teeth bent backwards and fell, like sharp, serrated knives.

They usually hunt on a small scale.

The first fossil remains of Megalodon were discovered in slate in a quarry in Oxfordshire, England, in 1818.

Since then, as many as 25 dinosaurs have been named Megalodon.

In fact, this name has been given to many theropod dinosaurs that cannot be clearly identified.

Huge jaws and other bones found in stone fields prove that Megalodon was a large and fearsome carnivorous dinosaur.

Megalodon was longer than two rhinos and twice as tall as an adult human.

Its large mouth was filled with large, pointed teeth, each of which was as large as the entire jaw of a small mammal at that time.

The teeth are curved, with serrated edges and roots deep in the jaw.

This way, even the most intense biting fights won't loosen the teeth.

The gentle plant-eating dinosaur was no match for the hungry megalodon.

In addition to its terrifying mouth, its hands and feet also have powerful weapons-long claws.

The claws are used to tear open the tough skin of prey and then shred the flesh beneath the skin.

Megalodon, the first dinosaur to be scientifically described and named, was a massive animal and a beast that hunted other animals brutally.

Its head is large and has curved teeth in its powerful upper and lower jaws, like a steak knife, with serrations at the top for biting fresh prey.

It has sharp claws on its "fingers" and "toes". With such weapons, Megalodon can attack forest-type herbivorous dinosaurs at any time.

The remains were very fragmented and may have been mixed with fragments of other theropod bones.

lived in Africa during the late Jurassic period.
