Can Raptors Kill Tyrannosaurus Rex?

There is no fossil evidence that raptors have this ability. Raptors of the same generation as Tyrannosaurus Rex are generally only two meters long. It is not worth the loss to kill Tyrannosaurus Rex at the risk of more than half of the population casualties, just as jackals don't provoke lions at all, even if they are alone. To be honest, Utahraptor may be a large raptor, but unfortunately, it is far from Tyrannosaurus Rex in terms of age and living place.
