He stated that the fossils were arranged in a consistent and reliable order in the sedimentary rocks that can be identified around the world. For example, the trilobite Paradoxides pinus, which lived during the Cambrian, will never be in the same strata as the Bothyurus extons, which lived during the Ordovician see figure below.
This principle allows for rocks to be dated using the fossils contained within. Today, we understand this as the result of evolution; however, this concept was understood in the late 's, over 50 years before Darwin published his ideas. Based on the fossil relationships, you can tell the relative age of the rocks and correlate, or match up, one layer to another across the world. The first, or oldest, strata in which a fossil is found in is called the first occurrence. The last strata, or youngest, that the fossil is found in is called the last occurrence.
The sequence of strata in which a particular organism is found, between the first and last occurrences, is called the range zone. This represents a distinct time zone in which the organism lived. For example, the trilobite order Harpetida has a first occurrence during the Cambrian and a last occurrence at the end of the Devonian. Therefore, anywhere we find a fossil from this order of trilobites, we know the strata are Cambrian to Devonian in age.
Fossils that have a limited range zone, were widely distributed during that time period, and are easily recognizable are called an index fossil or guide fossil. We can use the index fossils to identify the time period that the rocks are from. This problem has been solved! See the answer. Previous question Next question. Get more help from Chegg. Get 1:
Your task is to complete portions of Lab 8 in your lab manual (p. ). Part 1. Short Answer.

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order.
Geology can also include the study of the solid features of any terrestrial planet or natural satellite such as Mars or the Moon. Modern geology significantly overlaps all other earth sciences , including hydrology and the atmospheric sciences , and so is treated as one major aspect of integrated earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure.
