Fossils aren’t used only to understand individual organisms.
Geologists also use fossils for what’s called biostratigraphic correlation, which allows researchers to match layers of rock in different locations by age based on how similar the fossils in each rock layer are.
Have you ever wondered how scientists know so much about the earth's past?
Fossil remains can give us insight into how prehistoric plants and animals obtained food, reproduced and even how they behaved.
At times fossils can also provide evidence for how or why the fossil organism died.
Typically, hard structures like bones, shells, and teeth fossilize more often than soft-bodied structures like tissues or plant leaves, but as is seen with the horsetail relative, plants can become fossils.
The other type of fossil is called a trace fossil, where evidence of the organism but not the actual organism is preserved, such as a track, a burrow, a nest, or even feces.
Try It risk-free Fossils provide scientists with many clues about Earth's history, offering evidence of dinosaurs and strange plants that existed in the past.
This lesson will define a fossil, look at different types and characteristics of fossils, and then describe how fossils are formed.
Or how they know a relative of today's horsetail plant lived 150 million years ago?
Paleontologists, or scientists who study fossils, help paint a picture of what life used to look like on earth millions of years ago.
This information can be used to help understand when different layers of rock were formed even when large distances separate them (reference 1).
Environmental interpretation, or understanding how the Earth has changed over time, is another area where fossils supply invaluable evidence.
Scientists use fossils to gather information about the lives and evolutionary relationships of organisms, for understanding geological change and even for locating fossil fuel reserves.Tags: Adult Dating, affair dating, sex dating
