[Titus Quinctius Cincinnatus]

To a certain extent, if the animal is found not to be quite so old, then it becomes difficult to make the case that the rocks are so very old.

Maybe the T. Rex just had very sharp claws and was able to dig into the rock, and then meticulous replace the rock back into place in such a way as to give the appearance of the rock never having been disturbed?

Either way, we KNOW that the T. Rex is billions and billions of years old, since that's what Richard Dawkins said.

“Either way, we KNOW that the T. Rex is billions and billions of years old, since that’s what Richard Dawkins said.”

And little Dickie Dawkins is never wrong, is he?

All good points... well placed sarcasm.
