Most Dangerous Dinosaurs and Prehistoric Mammals

Tyrannosaurus Rex

Tyrannosaurus, whose name means "tyrant lizard" in Ancient Greek, is a genus of coelurosaurian theropod dinosaur. It had an extraordinary bite force estimated at up to approximately 12,800 pounds, or 5,800 kilograms of force. This is considered the strongest estimated bite of any known terrestrial animal... read more

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 eyes faced forward, an adaptation known as stereoscopic vision and had an excellent sense of smell and hearing. Yes some dragons did have Stereoscopic vision, but the majority portrayed in GOT have sideways facing eyes. What is more while most Dragons had human like intelligence, this isn't to say T-rex was stupid- the theropod had a remarkably large brain relative to its body size and some recent studies show that it allegedly was as smart as a chimp.( which could have been helpful in outwitting and outsmarting dangerous prey) But it had three great advantages most dragons did not- A crushing bite force about 431 000 psi, enough to pulverize bones, and teeth shaped like railroad spikes, which even Smaug lacks. In addition, it was shockingly fast- computational analysis shows it could run at speeds of 26 mph covering huge strides, (more than most average sized humans, for short bursts, but as this was based on an elephant (Grefory S Paul's book, Field Guide to Dinosaurs), and that the leg... read more

Spinosaurus Aegyptiacus

A carnivorous dinosaur from the Cretaceous period, Spinosaurus aegyptiacus is best known for its elongated neural spines, which formed a sail-like structure on its back. It was native to North Africa and is thought to have been semi-aquatic, primarily feeding on fish. It's widely considered to be one... read more

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!
