Buz alleges a circular argument in regards to dating and the use of index fossils. Here is my understanding of the use of index fossils.
1. Fossils are usually found in sedimentary layers.
2. These layers usually can't be dated by the various radiometric dating methods
3. These layers can usually be found between igneous layers
4. Igneous layers
can be dated by the various radiometric methods.
5. these methods measure the amount of time since the igneous layer was deposited.
6. With the age of the igneous layers determined we can then determine that the age of the sedimentary layer between the two igneous layers is between the age of the igneous layers.
7. The age of the fossil in the sedimentary layer is therefore at least the same age as the sedimentary layer that it is found in.
8. If we consistently find a certain fossil organism in sedimentary layers that we can assign an age range to by the dating of igneous layers we can then reasonably assign that same age range to any sedimentary layer with that fossil organism in it.
no circular argument.
