Monster dinosaur T-rex may have actually been 70% bigger than we think

The tyrannosaurus rex is already considered one of the most terrifying animals to ever walk the earth.

Now experts have only added to horror after working out that some of the giant predators might have been 70% bigger than anything humans have so far uncovered.

Rather than topping out at 12m in length, two experts think it might have stretched to a scary 15m and weighed in at 15 tonnes.
