Because scientists can tell what happened in the past, what kind of animals lived at that time, and how old it was. A long time ago, we found a old harry elephant under the ice. Scientists found out what animals lived, and what they looked liked. They found some food still in its mouth, and they know now what they eat. Cool huh?
Artifacts are important to Historians (and Archaeologists) because they are actual evidence of past human activity. However fossils are NOT important to historians as they are too old, they ARE important to Geologists.
Geologists can use index fossils from rock layer B to correlate the age of the rocks in another location by matching the presence of these unique fossils. Index fossils are widely distributed and lived for a short period of time, making them useful for dating rock layers. By identifying the same index fossils in both rock layers, geologists can infer that they are of similar age.
Geologists use fossils to determine the age of rocks through a process called biostratigraphy. They identify the specific group of fossils present in the rock layer, known as index fossils, that have a known age range. By comparing the index fossils to a geological time scale, geologists can estimate the age of the rock layer.
Index fossils are useful to geologists as they are distinctive fossils that can be used to date the age of rock layers based on their known age ranges. By identifying and studying index fossils in rock layers, geologists can determine the relative age of the rocks and establish a timeline of Earth's history. This helps geologists correlate rock layers across different locations and construct a more accurate geological history of an area.
Index fossils help geologists determine the relative age of rock layers by comparing the fossils found in them to known ages of fossils. By identifying specific index fossils, geologists can correlate rock layers from different locations and help determine the chronological order of events in Earth's history.
In what ways are fossils useful to geologist?

Because organisms that became index fossils lived only during specific intervals of geologic time, geologists can estimate the ages of rock layers based on the particular index fossils they contain.
Sedimentary rocks are most useful for historical geologists because they can contain fossils and provide information about past environments and the Earth's history. Sedimentary rocks also often preserve layers that can be used to determine the relative age of rock formations.

Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
Geologists use fossils to interpret past environments, age rock layers, and understand the history of life on Earth. Fossils can provide information about the evolution of species, past climate conditions, and even the movement of continents over time. By studying fossils, geologists can reconstruct the Earth's history and better understand geological processes.

It gives information to scientists about the past. It also provides a reference of time throught rock layers. It can identify and define geological periods of time.

Sedimentary rock are made of materials that could show what lived where. Also they are the only rock to hold fossils.
