However, as the rock accumulates, less and less of the fossil in question occur. Again, we have to look at the situation here and ask ourselves some questions. The presence of disease would result in smaller, weaker animals.

ICR is grateful to its dedicated constituents for enabling these fascinating scientific discoveries for almost a half century.

In the case of fossils, these long-dead specimens can be perfect clues for figuring out changes in environment and life conditions.

If you've ever found a fossil, it's pretty clear that the world has changed a great deal since the organism that formed that fossil lived.

In fact, they often find predators and prey locked together in a fight not only with each other but also with the tar.

The fossils are so intertwined that it's hard to tell the bones apart!

At the bottom of the strata, or rock layer, that you're looking at, you notice a lot of tropical ferns as fossils. As such, this is probably a pretty good indication that there was some significant level of climate change to allow for this to happen.

Remember, the deeper you go in the rock, the older the fossils and rocks.Through radioactive dating, we can get a range of formation from the surrounding materials due to the amount of certain isotopes left in a mineral.Likewise, relative geological aging lets us say that the fossil is probably older than anything that formed on top of it but younger than anything under it. When most of us think of fossils, we think of the remains of the bones and teeth of an animal.Fossils are, first and foremost, surrounded by geology.Whether it's the remains of a tar pit, sand, or good old-fashioned rock, a fossil's surroundings offer plenty of clues.Fossils don't just show differences in climate but can also show changes in life conditions.
