What three kinds of information can geologists gather from a study of fossils?

The three kinds of information can geologists gather from a study of fossils is amber fossil, trace fossil, and the carbon film. Wait a second, no that's not right. Those are just three kinds of fossils. Those aren't three kinds of information.

1. Fossils tell scientists the types and sizes of animals that lived in the distant past;
2. Tests made on fossils tell scientists approximately how long ago they lived;

3. The types of materials in which fossils are found tell scientists the area where the fossil first died, the cooling rates of some different materials, and the times of lava flows, as well as other items of information;

4. Comparing different fossils of the same type, from different areas, tells scientists the times of certain geologic events, such as an ice age, or a volcanic eruption;5. The layers of rock (or soil) in which fossils are found can tell scientists some of the geologic history of the geographical area in which the fossil was found. For example, sometimes seashell fossils are found in the rock of high mountains! That can only mean that the high mountain was once on the floor of an ocean or river. Over time, plate movement, volcanic eruption, and earthquakes have moved the old ocean floor (or river bottom) 'way up to the top of a mountain

There you go.
