The Mosasaurs were another fearsome water dinosaur. These creatures could grow up to sixty feet long and had long, snake-like necks.
They could also swim powerfully and had sharp teeth that they used to hunt their prey. Mosasaurs were able to breathe under water and were some of the first creatures to use this ability to hunt.

Leedsicthys

Leedsicthys
Leedsicthys was a terrifying creature that lived in the ocean during the Late Cretaceous Period. This creature was about thirty feet long and had a long, snake-like neck. Leedsicthys had powerful jaws that it could use to attack its prey.
Liopleurodon

Liopleurodon
Liopleurodon was one of the largest and most fearsome water dinosaurs that ever lived. This creature could grow up to seventy-five feet long and had a long, snake-like neck.
Liopleurodon had sharp teeth and used them to hunt its prey. Liopleurodon could swim powerfully and could attack its prey from behind.
Helicoprion

Helicoprion
Fossils of the next beast are notorious for leaving behind only a wheel of teeth called a “tooth whorl.” As their teeth grew, their teeth turned inward and formed a spiral. The teeth in the center of the whorl are the oldest.
Livyatan

The first mammal on this list was like a turbo-charged sperm whale. It had the same size and power as its descendants, but it had 14 inch teeth lining each jaw. They currently hold the record for longest tooth ever known!

Dunkleosteus

Dunkleosteus
The Dunkleosteus was a huge fish that could grow up to 30 feet long. It had bony ridges instead of teeth, and its bite force was 8,000 pounds per square inch.
It is believed that its jaw muscles were so powerful that it could open its mouth in one-fiftieth of a second, quickly vacuuming food inside.
And because its ridges were so sharp, it had no problem biting through the bony bodies of other armoured fish.
Scientists have had to make educated guesses as to what the Dunkleosteus looked like, since only its armoured skulls are left as fossils. We know that it had an incredibly strong head to match its powerful bite.
Mauisaurus
The Mauisaurus was a massive predator that lived during the Late Jurassic Period. This creature could grow up to 100 feet long and had an unusual sail on its back.
The sail was used to help it swim faster and hunt in deeper water. The Mauisaurus had a long, powerful jaw that it could use to attack its prey. It also had sharp teeth that it could use to tear apart its prey.
Conclusion:
These water dinosaurs were some of the most fearsome creatures to ever walk the earth. They were fast, powerful and deadly. No one was safe in the oceans when they were around.
