Most Dangerous Dinosaurs and Prehistoric Mammals

The Top Ten
1 Spinosaurus Aegyptiacus

Although a Spino is way cooler than a Rex, it would only win a fight in an aquatic area. Against a Rex, that's the only thing it has going for it. (And my username has Spino in it, so that's a thought. ) And also, what about the Sauropods? Are you forgetting that dinos are animals too, and if you put a 50-ton foot on its head it WILL die?

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?

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.

2 Tyrannosaurus Rex Tyrannosaurus, meaning "tyrant lizard", from the Ancient Greek tyrannos, "tyrant", and sauros, "lizard" is a genus of coelurosaurian theropod dinosaur. It also had a tremendous bite force, the strongest of any Dinosaur and living terrestrial animal. Its bite force reached up to 12,800 pounds (roughly ...read more.

heh. While it MIGHT be a contender for the strongest predator, and it's PROBABLY more powerful than a Spino, it will get demolished by ANY large sauropod. Predators are WEAK! That's how nature works! A lion will get demolished by a hippo! A raptor is weaker than a trike! A rex is weaker than a trike! Pay attention in nature documentaries!

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
