How do you organize fossils record from youngest to oldest

I love fossils! Ok so the  oldest layers are on the bottom, and the youngest layers are on the top. Because sediments sometimes include once-living organisms, sedimentary rock often contains a lot of fossils. Fossils are once-living organisms that have been turned into rock, in which the shape or form of the organism can still be still seen. Hope it helps!

work yay..other than that pretty good actually it hot though (≧▽≦)

answer; i believe that the correct answer is culture based resources;
