sedimentary rock
Fossils can show the kind of environment animals lived in millions of years ago. They can also show how certain animals have evolved. Artifacts can show the kind of society humans lived in at a certain time.
Fossils are the remains of plants and animals that have been turned to stone.
: the science that deals with the fossils of animals and plants that lived very long ago
Fossils help us learn about the past, like if a fish fossil was in your backyard, then your backyard was covered with water. They also help us with the fossils where the setting was then, and what animals lived there.
If the fossils that the scientists find are very evolutionarily similar, for example, if they are the same species or genus, then that means that the sedimentary rock layers have some correlation to each other since the two extinct animals that turned into the fossils most likely lived during the same time period. This hints that the two rock layers were both exposed to the atmosphere during the same time period.

Sedimentary rock, because it was once a sediment in or around which animals or plants once lived.

Indeed they did. Of course, it wasn't Illinois then, but they walked over the same area of the Earth. Dinosaur fossils aren't much found there now, because the kinds of rocks they fossilized in are mostly out west. You can find fossils in Illinois, but they're found animals and plants that lived before the dinosaurs.

Because organisms that became index fossils lived only during specific intervals of geologic time, geologists can estimate the ages of rock layers based on the particular index fossils they contain.
because of climate change. Climate change killed the animals that lived there
Fossils and other naturally preserved parts of their bodies.
Uplift of sedimentary layers caused be continental drift and collisions push the oceanic fossils skyward.
