This menacing predator used to have a large and strong jaw, as well as sharp teeth for tearing meat. The biting force of a tyrannosaurus equalled three tonnes, or, approximately the weight of an average-sized elephant.
They used to have powerful and large back legs, as well as very small arms, which in no way could be used for walking. Perhaps, just like the teeth, they were used for tearing the food apart.
According to modern-day calculations, this dinosaur could not have exceeded a maximum of 40 km speed and used to take several seconds to turn at a 45-degree angle.
