Paleontologists
use fossil remains
to understand different aspects of extinct and living organisms. Individual fossils may contain information about an organism's life and environment. … Studying oyster fossils can help paleontologists discover how long the oyster lived, and in what conditions.
How do paleontologists understand fossils?
Radiometric dating
allows ages to be assigned to rock layers, which can then be used to determine the ages of fossils. Paleontologists used radiometric dating to study the fossilized eggshells of Genyornis, an extinct bird from Australia.
How fossils help us understand the past?
Fossils give us
information about how animals and plants lived in the past
. … 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.
Why is a paleontologists work important?
Paleontologists
study fossils, the remains of ancient organisms
. This work provides insight into Earth's history, including climate changes, catastrophic events, evolution and geologic composition. … Many paleontologists work in academia, while others help petroleum producers locate fossil fuels.
How does paleontology help us?
Paleontological resources, or fossils, are any evidence of past life preserved in geologic context. … They
show us how life, landscapes, and climate have changed over time and how living things responded to those changes

Why is it important to know the age of fossil?
Determining the ages of fossils is
an important step in mapping out how life evolved across geologic time
. … Biostratigraphy enables scientists to match rocks with particular fossils to other rocks with those fossils to determine age. Paleontology seeks to map out how life evolved across geologic time.

What if there were no fossils?
If there were no fossils and you could
only use the characteristics of the rock layers it would be even harder

are the fossilised faeces of animals that lived millions of years ago. They are trace fossils, meaning not of the animal's actual body. A coprolite like this can give scientists clues about an animal's diet.
