Paleontology
Relative dating. Paleostratigraphy correlates layers of rock using index fossils found within them.
by using a X-ray
Correlation by Fossils (index fossils) - Matching rock units of similar age on a large scale by using index (or guide) fossils (fossils that were widespread geographically and lived only a short time). Allows widely separated rocks of different composition to be correlated. Overlapping time ranges of several sets of index fossils are typically used.
The main periods of geologic time are eons. Then eons are divided into eras. All these divisions are done using geological strata. That is, layers of earth or stone, etc. that represent periods of some kind of similar behavior on the earth.
Rate per period
I love fossils
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.

Paleontology.
Paleontology
Periods mean eras centuries ages
By definition, we could say all three fossils are 'ancient'. Fossils provide an ancient record of plants and animals.
You can dig up fossils underground by using the Explorer Kit in the Key items pocket of your bag :)

Well they originate from fossils which are non-renewable.
