Relative dating of fossil

are the preserved remains or traces of animals, plants, and other organisms from the remote past.

The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record.

2) To familiarize students with the concept of half-life in radioactive decay.

3) To have students see that individual runs of statistical processes are less predictable than the average of many runs (or that runs with relatively small numbers involved are less dependable than runs with many numbers).

However, by itself a fossil has little meaning unless it is placed within some context.

The age of the fossil must be determined so it can be compared to other fossil species from the same time period.

Historians, for example, know that Shakespeare's play Henry V was not written before 1587 because Shakespeare's primary source for writing his play was the second edition of Raphael Holinshed's Chronicles, not published until 1587.

Thus, 1587 is the post quem dating of Shakespeare's play Henry V.

These types of fossil are called trace fossils (or ichnofossils), as opposed to body fossils.

Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free.

These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.

Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology.

This usually requires what is commonly known as a "dating method".
