Fossils are NOT dated directly - if they are actual "fossils" - lithified remains. That's why you get some rather wide ranges in the dates ("+ or - so many years"). What is dated are the volcanic layers, if any, that are present above or below the particular fossil find.
The only "assumption" made here is that 1) Atoms exist, and 2) That atomic nuclei decay at the same observed rates in the environment.
You have yet to address your false claim about "assumptions" from last night.

I would argue that we cannot even nail down hard dates for many contemporary things (such as NT manuscripts) yet we accept when someone says a spoon is 40,000 years old. Cavemen used it to eat fruity pebbles.

Your analogy to finding, say a distinctive amphora (pottery) from the Minoan culture and being able to date it with an "educated date" can also be applied to fossils.
Fossil types appear and disappear throughout the geologic column. If someone turned up in a pawn shop with a certain type of trilobite fossil, the guy behind the counter could consult a record of fossils and date that particular fossil to a particular era. This would be analogous to your "educated date" of pottery remains.
Just what NT manuscripts are you puzzling over? One problem here is that it's only been 2,000 years since the New Testament actually occurred. 2,000 years, unfortunately, is often the "+ or -" in radiocarbon dates. It's too recent for a lot of radiometric dating techniques.
Thermoluminescence is available - but just tell someone that you want to "burn" a portion of their 1,400 year old manuscript. Radiocarbon requires the destruction of a sample as well. That's a hard sell. Most people would just tell you that they'd rather wait for more info or new techniques to be invented.
