It is debateable, yes. But the timeline in the Bible seems to be a bit more accurate, seeing everything in there is technically a written record, so that's what I base my theories of the Earth's age off of.
Okay, since this is not an old earth to new earth debate, I will leave off on that.
But I do not understand your former comment. Are you asking if a tailbone is classified as a vestigal structure? Yes, I am pretty sure it is. Google seems to prove me right, although the first link was confusing. I do not know when though.
