The geological eras are determined by the presence of different types of fossils.

Explanation:

The age of rock layers is determined by the presence of different types of index fossils. Index fossils are assumed to have only existed in specific periods of times.

In a form of circular reasoning the age of the index fossils is determined by the Darwinian theory of evolution. The simpler the fossil the older the fossils are assumed to be. The the fossils are arranged in a what is called the geological recorded based on their assumed age. The geological record is then used as one of the strongest evidences of Darwinian evolution.

Some types of fossils are found through out large parts of the geological record. Others are not found in the earlier parts of the geological record. Some are not found in the newer parts of the geological record. The disappearance of certain fossils in the geological record is explained as the result of Darwinian evolution.

However some index fossils have been recently been found alive not extinct as proposed by the geological record and the Darwinian theory of evolution. So these fossils though they seem to have disappeared form the geological record still exist. Fossils disappear from the fossils record because this is required by Darwinian theory of descent through modification even if the fossils do not truly disappear.
