10. Shastasaurus

Ichthyosaurs were marine predator that looked like modern dolphins, and can reach enormous sizes, they lived in the Triassic period about 200 million years ago. Shastazavr, the largest species of marine reptiles ever found, was the ichthyosaurs, which could grow to over 20 meters. It was much longer than most other predators. But it is one of the largest creatures ever to swim in the sea, it was not quite scary predator; Shastazavr fed by suction, and eat mostly fish.
9. Dakosaurus

Dakosaurus was first discovered in Germany, and, with a strange reptilian and yet ichthyoid body, he was one of the top predators in the sea during the Jurassic period. Its fossils were found in a very wide area – they are everywhere, from England to Russia and to Argentina. Although it is usually compared to modern crocodiles, Dakosaurus could reach 5 feet in length. Its unique teeth led scientists to believe that he was the main predator during his terrible reign.
8. Thalassomedon .

Talassomedon pliosaurs treated group, and its name translates from Greek as “Lord of the Sea” – and for good reason. Talassomedony were huge carnivores 12metrov achieved before long. He had almost 2 meter fins, allowing it to float in deep with deadly efficiency. His reign as the predator was not until the late Cretaceous period, until it finally came to an end when, in the sea, new larger predators, such as mosasaurs
7. Nothosaurus

Nothosaurus, which reached a length of 4 meters, were aggressive predators. They were armed with a mouth full of sharp, outwardly directed teeth, which indicates that their diet consisted of squid and fish. It is believed that Nothosaurus, were mostly predators ambush. They used their smooth reptilian physique to sneak up production and catch her off guard in the attack. It is believed that Nothosaurus pliosaurs were relatives, another species of deep-sea predators. Data derived from fossils suggest that they lived in the Triassic period about 200 million years ago.
6. Tylosaurus

Tylosaurus treated mind mosasaurs. He was enormous, and reached more than 15 meters in length. Tylosaurus a meat-eater with a very varied diet. Their stomachs were found traces of fish, sharks, smaller mosasaurs, plesiosaurs, and even some flightless birds. They lived in the late Cretaceous period in the sea which covered the territory of modern North America, where they are firmly placed on the top of the marine food chain for several million years.
5. Thalattoarchon Saurophagis

Only recently discovered, Talattoarhon was the size of a school bus, reaching nearly 9 feet long. This is an early type of ichthyosaur that lived during the Triassic period, 244 million years ago. Because they appeared shortly after the Permian extinction (the largest mass extinction on Earth when scientists believe 95% of the marine flora and fauna have been destroyed), his discovery gives scientists the opportunity to take a fresh look at the rapid recovery of the ecosystem.
4. Tanystropheus

Although not strictly Tanistrofey marine life, his diet consisted mainly of fish, and scientists believe that the majority of their time was spent in the water. Tanistrofey a reptile that can reach 6 feet in length, and is thought to have lived in the Triassic period, about 215 million years ago.
3. Liopleurodon
Lioplevrodon a sea reptile and reach more than 6 feet long. He basically lived in the seas that covered Europe during the Jurassic period, and was one of the top predators of their time. Some of his jaw is believed to have reached more than 3 meters – that’s about the distance from floor to ceiling. With such huge teeth, it’s easy to see why Lioplevrodon dominated the food chain.
2. Mosasaurus

If Lioplevrodon was huge, the mosasaurs was colossal. Data derived from fossils suggests that mosasaurs could reach up to 15 meters in length, making it one of the largest marine predators of the Cretaceous. Mosasaurs head was like the head of a crocodile, she was armed with hundreds of razor-sharp teeth that could kill even the most well-protected opponents.
1. Megalodon

One of the largest predators in the sea of ??history and one of the largest sharks ever recorded, Megalodon was incredibly scary creatures. Megalodon scour the depths of the ocean during the Cenozoic era, 28 – 1.5 million years ago, and had a much larger version of the great white shark, the most terrible and powerful predators in the oceans today. But while the maximum length of which modern great white shark can reach is 6 meters, Megalodon could grow to 20 meters in length, which means that they were more than a school bus!
