I know - technically they are not dinosaurs; they are marine reptiles. But they are still bloody cool.
I would never surf if these things were still patrolling the oceans.

Monsters of the Mesozoic
The mosasaur was gigantic; the largest mosasaur found was Tylosaurus, more than 57 feet long. Its jaws were armed with rows of backward-pointing teeth to hold prey securely in its mouth. Mosasaurs also had a bizarre-looking additional set of teeth that could hook into the severed flesh of its victim and push it down its gullet. Mosasaurs didn’t chew; they gulped. They were probably ambush predators, lying in wait on the ocean floor. Then, using their long tails and powerful flippers, they would swiftly attack the unsuspecting prey from below.
