Re: Fossilosophy
I'm not aware of any significant changes in the estimated the age of the Earth in the last 20 years - it's still around 4.5 billion years.
And I don't know why you brought up carbon dating since it was never used to date fossils. The method itself is still in widespread use in archaeology and work on refining it continues - especially for ages in the range 11,000 - 50,000 years bp (before present).

Re: Fossilosophy
Carbon dating has a limited range and does not directly apply to a lot of material (it only applies to carbon derived directly from the atmosphere). It has no relevance to geology since most of geology lies outside the useful range of dates and much of the material involved contains no carbon at all (except perhaps as a trace contaminant).
Carbon dating has never been used to support dates of 60 million years (it absolutely cannot) and it is not very reliable for dates of even 60,000 years. But there is absolutely no chance of geological dating changing by three orders of magnitude as you suggest.
I strongly suggest that you learn the basics of the subject, because it is quite clear that you don't know what you are talking about.
