1/ you dig them up or crack them out of rocks - the earth must have changed to bury them.
2/ If you find a whole lot of fish fossils up in a mountain then there is a good chance that the mountain was once not as high as it is now
3/ If you find lots of a particular type of fossil all over the place in some strata, then none at all after that it suggests that conditions changed so that the animals/plants either died out or moved away (or that conditions changed so that their fossils were no longer preserved maybe they were completely consumed by mountain climbing jellyfish which leave no fossil record - would this count as a change in the earth or just a change?) - either way something changed.

Thousands of layers of sedimentary rock confirm the long history of the changing surface of the Earth and the changing life forms whose remains are found in successive layers. The youngest layers are not always found on top, because of folding, breaking, and uplift of layers.
Many thousands of layers of sedimentary rock provide evidence for the long history of the earth and for the long history of changing life forms whose remains are found in the rocks. More recently deposited rock layers are more likely to contain fossils resembling existing species
Fossils provide important evidence of how life and environmental conditions have changed.
Extinction of a species occurs when the environment changes and the adaptive characteristics of a species are insufficient to allow its survival. Fossils indicate that many organisms that lived long ago are extinct. Extinction of species is common; most of the species that have lived on the earth no longer exist.
Biological evolution accounts for the diversity of species developed through gradual processes over many generations. Species acquire many of their unique characteristics through biological adaptation, which involves the selection of naturally occurring variations in populations. Biological adaptations include changes in structures, behaviors, or physiology that enhance survival and reproductive success in a particular environment.
