If you are going to write a comment make sure you've got your facts right first, nothing like making yourself look like an idiot on youtube! :D
Basilosaurus - Was a species of whale that hunted other whales and dolphins, it was a very successful predator until its large prey started to run out and the climate changed.
Dunkloestes - Was one of the worlds first super fish, it was built like an under water tank and had bone ridges instead of teeth. it went extinct in the first worldwide mass extinction millions of years ago.
Elasmosaurus - It lived in the late Cretaceous period and was a 14m killer and it had more teeth in its mouth than most other sea reptiles at the time and went extinct at the same time as the dinosaurs.
Helicoprion - Was a primitive shark that existed before the Dinosaurs, and it could roll its jaw so that it could snap up fish from a distance.
Kronosaurus - It is one of the largest of the pliosaurs and is named after the greek titan Cronos.
Liopleurodon - This is one of the most debated species of sea reptile as its correct length isnt known. it thrived as the apex predator of the Jurassic period.
Livyatan Melvillei - Some say that it is like a cross between a Sperm whale and an Orca, they were equipped with large teeth and travelled in pods like other whales. this species was strong enough to actually kill the Megalodon as they could use sonar shock waves to stun the Megalodon and then rip it apart.
Megalodon - Is the biggest species of shark known to man. it is debated that they could actually still be alive today, but this is not possible as the first 100ft of the ocean has been explored and the Megalodon could not live further down than this depth or the pressure would kill it.
Mosasaur - It is thought that this is one of the closest relatives to snakes and other reptiles. when the extinction came to other large marine predators, this species took the role of apex predator until it became extinct.
Sarcosuchus - Commonly known as 'SuperCroc' or the 'Dinosaur Killer' was one of the largest species of crocodiles ever to live. it was twice as long as the salt water crocodile and weight from 8-10 tones.
