Most Dangerous Dinosaurs and Prehistoric Mammals

The Top Ten

1 Spinosaurus Aegyptiacus

Buddy, T-Rex has a stronger bite, and guess what, Spino has only biggest because of it's dumbass sail. Even though Spino has bigger claws, it wouldn't be useful when you have a opponent with a 6 ton per square inch bite.

It's the largest dinosaur carnivore known to date, that could also swim!

It can kill a T-Rex! Why is this less deadlier than those T-Rex?

I AGREE EVEN IF IT HAS WEAK JAWS IT CAN STILL CHOMP AND SCRATCH ANDTAIL WHIP (so many and's)

This would have been the most terrifying beast of all time, and has enjoyed the reputation of being woven into folklore and pop culture. Those who say a dragon breathing fire like those from the Talon Saga or popular GOT series would win against a T-Rex would be damn wrong. All Dragons from Western mythology, yes can breathe fire, but have evolved doing so at a great cost-most (with the exception of few large robust wyrms) have an exceptionally weak bite force, even less than that of a gorilla or a Grizzly bear, and only comparable to that of a leopard or a Perentie monitor. Therefore, while some variants can secrete venom, even those that breathe fire cannot break the bones of the opponents they kill. Those who say T-rex was a scavenger due to its puny arm, you are incorrect. It is scientifically shown that T-rex's arms themselves were able to curl an impressive 80 kilograms or even more, despite limitations in their movement, thanks to large muscle attachments. Even more so, their ...more
