However, relative methods are , which is that if there are layers of deposits, those laid down first will be on the bottom and those laid down last will be on the top. However, geological strata are not always found to be in a neat chronological order.
The owner of this kit was Martin Hinton, curator of zoology at the time of the hoax.
These processes result in All of these processes confuse the stratigraphic record.
In many cases, however, it is possible to reconstruct the original sequence of strata so that they can be used for relative dating.
For instance, if we find a fossil bone below the strata 3 rock level shown above, we assume that the animal most likely lived at a time before that layer was formed.
However, we must be careful to note whether or not the fossil comes from the mixed strata zone of the filled in hole..
If not, then at least one of them must be physically out of context.
