You asked: What can we learn from studying fossils?

By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.

Why is studying fossils important?

Fossils are physical evidence of preexisting organisms, either plant or animal. … Fossils of any kind are useful in “reading the rock record,” meaning they help us decipher the history of the earth. They can help us determine the geologic age and environment (the paleoenvironment) in which they were deposited.

What are fossils and why are they important to study?

As pieces of once living things, body fossils are evidence of what was living where and when. Trace fossils are valuable because they “animate” the ancient animals or plants by recording a moment of an organism’s life when it was still alive.

How do Fossils help scientists understand?

Fossils help researchers learn about plants and animals that existed long ago, having since faced extinction or evolution to modern species. … Scientists can put together how the plant or animal looked based on its skeletal structure, discover what the animals ate, and where they lived and how they died.

If an animal is frozen like the baby mammoth mentioned above, again the animal must remain undisturbed for many years before found.
