Could you run faster than a T-Rex? The answer is: YES! (sort of...)

Although the giant meat-eating dinosaur is often famed for its ability to chase down its prey - something made popular in lots of films - researchers at the Dutch Naturalis museum have made a interesting discovery.

In fact, the infamous Tyrannosaurus rex is much slower than once thought and most likely moved at a human walking speed.

So, how did the scientists make this revelation? Read on to find out.

What did the researchers do?

Researcher Pasha van Bijlert at the Dutch Naturalis museum used a 3D computer model of "Trix", a female T-Rex skeleton.

He used a computer to add muscles to the skeleton to discover that the huge tail plays an important part in how the dinosaur moved and at what speed.

It's likely that the dinosaur's preferred speed was 4.61 kms (2.86 miles) an hour, close to the walking pace of humans and horses.

The team looked at leg muscles, as in previous studies, but also tail movement - which would minimise the amount of energy the dinosaur used.

"The tail would sway up and down with each step (like a giraffe's neck). If the step rhythm and tail natural (speed) were matched, the tail would resonate, maximizing energy storage," Van Bijlert said on Twitter.

By calculating the T. Rex's step rhythm researchers estimated its walking speed.

Could a human REALLY outrun a T-Rex?

It's difficult to say for certain.

The researchers said they were looking at the iconic predator's walking pace and are still researching its possible top speeds. So maybe you could run faster than the T-Rex can walk! Which is still pretty cool.

Unfortunately it can't be put to the test as dinosaurs died out more than 60 million years before people appeared on Earth.
