How do fossils show the history of the earth?

How do fossils show the history of the earth?

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.

How do fossils contribute in terms of studying history of the earth?

Fossils are very useful to the study of tectonic history. When a fossil of a given species is found on several modern continents, it gives a strong indication that these continents were previously unified. Finally, fossils show us the long history of life and the past and current evolution processes on Earth.

What do fossils tell?

Fossils are the remains or traces of ancient life that are usually buried in rocks. Examples include bones, teeth, shells, leaf impressions, nests, and footprints. This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one another.

What are fossils and what are they used for?

Some species with a broad distribution on Earth and a short-term life (Ammonites for instance) are great indicators to identify certain geological periods. Finally, fossils show us the long history of life and the past and current evolution processes on Earth.

How are fossils used to date sedimentary rocks?

Fossils are also used to date sedimentary rocks. Some species with a broad distribution on Earth and a short-term life (Ammonites for instance) are great indicators to identify certain geological periods. Finally, fossils show us the long history of life and the past and current evolution processes on Earth.

How are fossils organized on the geologic time scale?

Fossils Through Geologic Time. The Geologic Time Scale is a way of organizing Earth’s 4.5 billion-year history. The time scale is divided into four large periods of time—the Precambrian, Paleozoic Era, Mesozoic Era, and Cenozoic Era. National parks preserve fossils from each of these time blocks. The Precambrian (prior to 542 million years ago)…
