GEOL Lecture 4: Deep Time: Dating the fossil record

You've got two decay products, lead and helium, and they're giving two different ages for the zircon. For this reason, ICR research has long focused on the science behind these dating techniques. These observations give us confidence that radiometric dating is not trustworthy. Research has even identified precisely where radioisotope dating went wrong. See the articles below for more information on the pitfalls of these dating methods. Radioactive isotopes are commonly portrayed as providing rock-solid evidence that the earth is billions of years old. Since such isotopes are thought to decay at consistent rates over time, the assumption is that simple measurements can lead to reliable ages.

18.5A: The Fossil Record as Evidence for Evolution

Because they accuracy often rare, primate fossils are not and good index fossils. Organisms like pigs and rodents are more typically used because they are more common, widely distributed, and evolve relatively rapidly. Using the principle of faunal succession, if an unidentified fossil is found in the same rock layer as an index fossil, the two species must have existed during the carbon period of time Figure 4.

A fossil from Classical Latin : fossilis , literally "obtained by digging" [1] is any preserved remains, impression, or trace of any once- living thing from a past geological age. Examples include bones , shells , exoskeletons , stone imprints of animals or microbes , objects preserved in amber , hair , petrified wood , oil , coal , and DNA remnants. The totality of fossils is known as the fossil record. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance.
