We speak effectively of all kinds of dinosaurs and beings that have lived here for millions of years and that today, thanks to the fossils, we can discover and name. They were large animals, giant and threatening animals.

Continue this YourCatCareguide article to discover marine prehistoric animals .

The Megalodon or Megalodon

The Planet Earth is divided into terrestrial surface and water representing 30% and 70% respectively. What does that mean? That there are presumably more marine animals than terrestrial animals hidden in all the seas of the world.

The difficulty of investigating the seabed makes the task of finding fossils difficult and complicated. Due to these investigations new animals are discovered each year .

It is a large shark that inhabited the earth until a million years ago. It is not known for sure if he shared the habitat with the dinosaurs but he is undoubtedly one of the most frightening animals in prehistory. He was about 16 meters long and his teeth were larger than our hands. This undoubtedly makes him one of the most powerful animals on earth.

The liopleurodon

It is a large marine and carnivorous reptile that lived in the Jurassic and Cretaceous. It is considered that liopleurodon had no predator at that time.

The size of this generates controversy on the part of the investigators although generally it is spoken of a reptile of some 7 meters or more. What is certain is that his huge fins made him a lethal and agile hunter.

Livyatan melvillei

While the megalodon reminds us of a giant shark and liopleurodon a marine crocodile, the livyatan is undoubtedly a relative distant from the sperm whale.

It lived about 12 million years ago where it is now the desert of Ica (Peru) and was discovered for the first time in 2008. Media about 17.5 meters in length and watching its huge teeth there is no doubt that it was a terrible predator.


The size of the great predators was also marked by the size of the prey they had to hunt, as is the case of dunkleosteus, a fish that lived 380 million years ago. It was about 10 meters in length and it was a carnivorous fish that ate even its kind.

Sea Scorpion or Pterygotus

It was named in this way because of the physical resemblance to the scorpion we now know, though in reality they are not related. Descended from the family of xiphoses and arachnids. His order is Eurypterida.

At about 2.5 meters in length, the scorpion of the sea is devoid of poison to kill its victims, this would explain its later adaptation to fresh water. It was extinct 250 million years ago.
