How can you tell if a rock contains a fossil?
It is also a good idea to look for signs that the rock contains a fossil before trying to break it, part of a fossil may be visible on the surface of the rock. You can identify the limestone by it's lighter grey colour and hardness, it should be quite hard to break without a hammer.
What should you do if you find a fossil?
If you find a fossil, the location is as important as the fossil itself. Photograph it and note any visible features (for scale, include a coin or pen). Locate it on a map using permanent landmarks (use GPS if available). Leave it buried.
Does your tongue stick to fossils?
If your tongue sticks ever so slightly to the fossil-in-question, there's a good chance it could be fossil bone. If it doesn't, you just licked a dusty ol' rock, dude. The dino fossil lick will be stickier than a stone slobber because of the porous nature of bone.

Limestone is a sedimentary rock made almost entirely of fossils. Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago.
Fossils are not the remains of the organism itself! They are rocks. A fossil can preserve an entire organism or just part of one. Bones, shells, feathers, and leaves can all become fossils.
The paleontologist tells you that the fossil may be a different color than the rock and that the fossil is usually harder than the rock. The fossil bone will also have a different texture than the rock. That's the remnants of the internal bone structure.
