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?
fossils are the remain of living things from many million or billions years ago and form as rock form.Most of the fossils are form in sedimentary rocks. if you mean by fossils useful thing of fossils is that you can see the development of the animals or organisms that have existed many many years ago and you can study them. if you mean by fossils fuels they are use to be oils but now a days, fossil fuels have gone more than half of the fuji mountain. (the fuji mountain thing is the real thing, it was exhibit somewhere i can't remember)
They tell about the past, give answers/solutions about puzzles in the present now that'll help in remodifying the future.
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.
they find the hard part of the fossil
Index fossils are very important to geologists because they identify geological. The fossil snail is a particularly difficult animal to study.
Index fossils
Geologists use index fossils to define and identify geologic periods.
In what ways are fossils useful to geologist?
Geologists love sedimentary rock because the fossils give a quick reference to their date of formation and environment of deposition.

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.
Fossils help geologists discover new species. Fossils also explain and show the age of the specimen and change in life forms.
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.
they find the hard part of the fossil
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.
Geologists use the geologic column to classify layers of rocks and fossils that make up the Earth's crust.
Sedimentary rock are made of materials that could show what lived where. Also they are the only rock to hold fossils.

pictures are useful to historians because it helps them picture what it was like in the past
