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.

) is an earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time.

Geology can also refer generally to the study of the solid features of any terrestrial planet (such as the geology of the Moon or Mars).

By the 1830's Adam Sedgwick and Roderick Murchison established a correlation between the various types of fossils and the rock formations in the British Isles.

It was found that certain fossils, now referred to as index fossils, were restricted to a narrow zone of strata.

As a result it is always undergoing natural radioactive decay while the abundances of the other isotopes are unchanged.

The principle of faunal succession in the geologic record was established by direct observation as early as 1799 by William Smith. Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones.All carbon atoms have a nucleus containing six protons.Geology describes the structure of the Earth beneath its surface, and the processes that have shaped that structure.It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks.

It's just one of the tricks that have been used to make the work a little more precise. I believe he has confused the use of index fossils with evolution.
