The date was established by radiocarbon tests, and reinforced by a careful study of pollen found in clay samples recovered by the Maryland Geological Survey. If we assume that racemization occurs at a constant rate, which is a reasonable assumption, then we get a time scale that is more compressed even than the C14 time scale. The study of stratigraphy enables scientists to determine the age of a fossil if they know the age of layers of rock that surround it.
Such a scenario does not answer all of the questions or solve all of the problems that radiometric dating poses for those who believe the Genesis account of Creation and the Flood. This would imply that any date within 50, years by C14 dating is really at most 18, years, and even any date within a million years by conventional dating is really at most 18, years. Mar 14 - 7: This human nuclear activity will make precise dating of fossils from our lifetime very difficult due to contamination of the normal radioisotope composition of the earth with addition artificially produced radioactive atoms. However, under such acidic conditions, bone is rapidly dissolved. They say that organic matter in the fossils has to be old because evolution requires it and we know that evolution is true.

Thus any increase in instability due to external factors might affect C14 dating much less than dating based on isotopes with much longer half-lives. Brown RH Apr Answering questions concerning radiocarbon dating.
Misleading results can occur if the index fossils are incorrectly dated. For example, if a magma chamber does not have homogeneously mixed isotopes, lighter daughter products could accumulate in the upper portion of the chamber. Some of these other isotopes include: Thursday, February 14, - 7: An apatosaurus was found in late Jurassic strata of the Morrison formation, and excavation was done in and Could It Be Bacteria? The half-life of carbon is approximately 5, years.
