So, at the moment right before death, the amount of 14 C evidence for evolution radioactive dating match the atmospheric levels, but it would steadily decrease thereafter—specifically, there would only be half the expected amount after 5, years. My question is, how could the fossils be exposed for who knows how many millions of years to the ocean side erosionary forces, but you have to take your shoes of for fear of damaging them?
That's much longer than carbon's half-life — as a consequence, K-Ar dating doesn't work very well on things younger thanyears old, because so little of the 4K will have decayed in that amount of time.
