Fossil demonstrate organisms, geological structure or formations, that may not be present in our lifetime, due to extinction. Usually these can be classified, as a long time ago, if no documented evidence can support such an organism etc, at a specific time E.g a certain bug infossilizedtree sap, which was not present at 300ad, therefore it was formed earlier. . However, withmillennium old fossils, the age can be found through carbon dating. Carbon dating uses samples of carbon within the fossil, to determine the age of the chemical compound, and therefore the time at which the fossil was formed. Fossils come from decomposed matter, hardening around an object underground and experiencing forces and heat for thousands of years.
Many fern fossils are found in the very northern parts ,and fish fossils have been found inland. Both indicate that there has been some major continental change.
Fossils indicate several things about Earth's past: - the organisms that lived then, and by extension the organisms in their food chain - the climate in the area where the organism lived - how plate tectonics have moved landmasses that once were joined together
They provide evidence for animals that existed before and do not now. It shows proof of the different evolution. It also gives us comparisons of organisms we have today and where they possibly came from.

The study of fossils represent the evolution of species by the time period between when they became fossils and what the ancestory line is
fossiles indicate how the earth ha changed. the older stuff is at the bottom, and the newer stuff is at the top. over time the top lyer erodes and the fossals are exposed.

fossils.
Organisms on Earth have evolved and changed significantly over time.
This indicates that the layers of sedimentary rock that constain fish fossils (or any other marine fossil for that matter) indicate there once was a body of water lying over that are of the earth whether it being an ocean or just simply a lake.
Paleontology is the scientific study of fossils to understand past life forms and environments. By analyzing fossils, paleontologists can reconstruct the evolutionary history of organisms and piece together the Earth's history. Fossils provide valuable insights into the diversity of life and how ecosystems have changed over time.
That animals have changed over time
In rocks in most parts of the Earth.
Fossils are the remains or traces of past life in Earth's crust.
They can learn about evolution, as many living fossils have changed quite a bit over time.
