The problem with fossil dating methods Free nudist chat

Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

Index fossils are fossils that are known to only occur within a very specific age range.For example, in the 1940s the U-Th-He method was used.But these tests quickly became notoriously unreliable, as they indicated so many different "ages" for the same rock layer.It refers to results that were supposedly thrown off by isotopes added to or subtracted from a sample over time. But the fission tracks' microscopic scars, left in igneous rocks from decaying radioactive atoms, were eventually seen rock-altering event involving hot water.But again, since nobody was there to observe these events, this could just as well be another excuse used to explain away confusing dating results.
