Number 2 : Deinosuchus
https://qph.fs.quoracdn.net/main-qimg-cf514a28ca43b5487ca572705d6bfdc5
The word “Deinosuchus” is translated to “terrible crocodile” in Greek. This croc could grow up to 40 feet in length and weighs 5,500 - 11,000 pounds. Just so you know, the saltwater crocodile normally is 14 - 17 feet in length, the largest Croc ever recorded was Lolong, coming at 20.2 ft, and 2,370 pounds. So imagine a crocodile that is twice the size of that and 2- 5 times as heavy! Facts and Figures About Deinosuchus
Number 3: Megalania

And no, not Meglavania, Megalania. This is a giant monitor lizard that roamed Australia. It’s name means “giant roamer” and it certainly lives up to that name. The Megalania was thought to be around 25 feet in length and around 2 tons. This is pretty much a giant komodo dragon.
Number 4. Megalodon.

This guy (or girl) doesn’t need an introduction. This is basically a giant shark. The Megalodon is a giant shark that weighs over 60 tons. This sharks is about 3 times the size of an average Great White, and has a bite force 40,131 pounds per square inch, that is 5 times the bite force of a Tyrannosaurus Rex. The Megalodon
Last one for now : Megapiranha
https://qph.fs.quoracdn.net/main-qimg-d432ef79be0aec7fdde947dea7acd934
This is a 3 foot piranha that potentially has the largest bite force ever, and is 4 times larger than a normal piranha. However, unlike a normal piranha, it has two rows of teeth instead of one. Now I know it only has a bite force of 1,000 pounds per square inch, but in relation to it’s weight (20–25 pounds), that’s very impressive. Put it this way, a T-rex has a bite force of 3,000 pounds per square inch, but it’s weight is roughly 15,000 pounds. So a megapiranha can bite up to 40–50 times it’s own weight.
