This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.

The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.

Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

I find the whole subject of radioactive dating extremely confusing and I still can't quite get to grips with the well known carbon dating method.

Is it possible that carbon could have been altered dramatically due to some sort of unknown geological or atmospheric condition back then?

And lastly, What type of fossils would one be looking for or find when using carbon dating? Catherine Scientists usually don't use carbon-dating for most fossils since it's half life is fairly short in comparison to the fossil record.

Instead, fossils are dated using a variety of radio-isotopes including Potassium and Uranium.

The half-life of radio-carbon is about 5700 years and it can be used to date once-living material that is up to 50,000 years old.

My understanding is that elements have 'half-lives' and the half lives are always the same (or are they?

), which is the time it takes to turn into another element. ) years, then does that mean carbon dating can only be used that far back?

In Carbon Dating, material decomposes over time in accordance with its half-life. b) Is this only possible with organic matter/compounds?
