How do scientists use fossils to study Florida’s history?

Fossils provide important information about the past life on earth. Based on the types of plants and animals present in a rock unit, scientists can often determine what ancient climates were like as well. Fossils are also useful in correlating and determining the age of rock units.

How do scientists learn about life’s history through 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.

What do the fossils in Florida tell us about life and the climate of Florida in the past?

They help us decipher what life was like during specific periods of time. Fossils also indicate geographic and climate change. Florida was underwater. 50 million years ago, during the Cenozoic Era, Florida began to be exposed as the sea receded.

Why are fossils so important?

Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. … Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.

What are fossils very short answer?
