How do you tell if you found a fossil?
Mostly, however, heavy and lightly colored objects are rocks, like flint. Paleontologists also examine the surfaces of potential fossils. If they are smooth and do not have any real texture, they are probably rocks. Even if it is shaped like a bone, if it does not have the right texture then it is probably a rock.
What kinds of things most often turn into a fossil?
The remains become fossilized. Fossilization usually occur in organisms with hard, bony body parts, such as skeletons, teeth, or shells. Soft-bodied organisms, such as worms, are rarely fossilized. Sometimes, however, the sticky resin of a tree can become fossilized.
What 2 things do fossils reveal?

What 3 things does a fossil record show?
The fossil record provides evidence for when organisms lived on Earth, how species evolved, and how some species have gone extinct.
What are spiral seashells called?
These shapes are called logarithmic spirals, and Nautilus shells are just one example. Nature forms these spirals in the most efficient way possible, and mathematicians have learned to describe them, using Fibonacci’s sequence.
