Explain five important things that can be determined by studying fossils?me!

One thing is the age of the surrounding soil/rock.  By carbon dating the fossil, you can determine the age of the layer of rock, because it will be the same age.  You can also determine where a species used to live, and its environment, based on knowledge of location and your knowledge of the ecosystem back then.  You can also determine weather the animal was a carnivore, herbivore, or omnivore, if you have teeth fossils.  A fifth thing is you can tell when the animal was alive, also by carbon dating.

1:
fossils help us understand how things in the past looked, mainly how dinosours and other ancceint things look

2: 
helps us study things that dont excist today in time so that way we understand more how things use to work

3:
tells us how long things lived, the infomation we obtain about fossils can tell us how long ago things lived. for example if you know how long it takes for fossils to form u can aproximate how long ago something lived

im only able to name 3 sorry but i hope wut i did tell u helps :) also chika
