rex surely would have been able to eat people. There are fossil bite marks, matching the teeth of T. rex, on the bones of Triceratops and duck-billed dinosaurs such as Edmontosaurus, which were both over 50 times heavier than an average person. But that doesn't mean we would be hunted to extinction.
rex preferred to eat large animals such as other dinosaurs or even mammoths. While T. rex may have been capable of chasing and eating humans, it is unlikely that it did so on a regular basis.
At first it would likely be mesmerized by the human's appearance, as it's never seen one. It would be mindful, and realize the presence of another animal. But, unless being territorial or just very hungry, it's unlikely to attack you instantaneously.
For an adult T. rex, the stakes were high. “A 6-ton T. rex,” Healy said, “would need the same daily calories as 80 people” on a diet of 2,500 calories per day.
Given the chance, this predator likely wouldn't have hunted humans, either. Despite the famous fossilization of a battle to the death between a Velociraptor and a much-larger Protoceratops, paleontologists believe that Velociraptors mainly preyed on small mammals and reptiles.
No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.

Ibrahim's recent discoveries and skeletal reconstruction show that the Spinosaurus is the largest carnivorous dinosaur we know of. It is both longer and heavier than the Tyrannosaurus Rex!
Tyrannosaurus rex was one of the largest and most fearsome carnivores of all time.
For instance, researchers gave the T. rex model a powerful four-chambered heart, just like the hearts of crocodiles and birds. However, T. rex's two-chambered stomach is actually based on limited fossil evidence from "one amazing fossil with some preserved gut contents," Brusatte told Live Science in an email.
rex would have seen you whether you stood still or put a sheet over your head! Because no fossilised T. rex retina has been found (or probably ever will be), we will never know whether their eyes were adapted for night vision.
rex was an aggressive dinosaur throughout its life, and that aggression extended towards its own species.
Except for some carnivorous dinosaurs, Tyrannosaurus rex is also afraid to provoke some herbivorous dinosaurs, and Ankylosaurus is one of them. It was equipped with a powerful tail club that could be swung with enough force to shatter bone.
In addition to a thin coat of dinofluff, the body of T. rex was covered in hard little scales. Other dinosaurs - like some of the spiky ankylosaurs - had thick coats of bony armor that would have provided more resistance, but T. rex didn't have the same equivalent of a bulletproof vest.
(Though 12 miles per hour approaches the top speed of a typical human, depending on conditioning—it equates to a 20-second 100 meter dash or a 5-minute mile—the T. rex's slow acceleration and inspiring teeth would give the average runner a reasonable chance of outsprinting or outmaneuvering the lumbering predator.)
Humans survived when the Sun was blocked out
There is evidence that a kilometer long asteroid crashed into Southeast Asia around 800,000 years ago — and our ancestors had survived it. The asteroid did impact human evolution and blocked out the Sun for years with the dust it threw up. Yet, humanity was not wiped out.
rex tasted more like poultry than, say, beef or pork. Its flavor would likely have been closer to that of a carnivorous bird—perhaps a hawk—than a chicken. What does a hawk taste like? It's probably not far off from the dark meat of a turkey but would be more pungent because of its all-meat diet.
Spinosaurus was an enormous theropod dinosaur that lived around 95-70 million years ago in the Late Cretaceous. It's the longest carnivorous dinosaur currently known, around three times the length of an African elephant and more than 20% heavier.
A relative of Tyrannosaurus rex didn't share the infamous carnivore's appetite for meat, a new study finds. Instead, the newly discovered 9.8-foot-long (3 meters) dinosaur munched on plants about 145 million years ago during the Late Jurassic period.
Giganotosaurus and Tyrannosaurus Rex did not live on the earth at the same time. Giganotosaurus was bigger and faster, but T-Rex had a stronger bite force and more teeth. In a fight between Giganotosaurus and T-Rex, the Tyrannosaurus would win.
In a T-Rex vs Spinosaurus fight, the T-Rex would come away victorious. The Spinosaurus does have the benefit of being able to ambush a T-Rex at the edge of the water, and that might be the lone scenario where the T-Rex loses.
One particular dino could have withstood gunfire more effectively than others: a tank-like creature called the Ankylosaurus. These massive dinosaurs sported incredibly strong armor — bony plates that covered their backs, skulls, and even their eyes and cheeks.
The giant jurassic dinosaur Allosaurus was a scavenger, not a predator.
