Some examples of non examples of fossils are as follows: knobby rocks, beautiful stones, bones. All fossils are rocks, and if bone fossils are found they will be much heavier than normal bone.
Non-examples of fossils can include but not limited to:•A seashell found on the beach•A piece of driftwood•A footprint that your dog left yesterday
tuna and salmon

Two examples of isotopes commonly used to date fossils are Carbon-14 and Potassium-40. Carbon-14 is effective for dating relatively recent organic materials (up to about 50,000 years old) due to its relatively short half-life of 5,730 years. Potassium-40, with a half-life of about 1.3 billion years, is used to date much older fossils and geological formations. Both isotopes help scientists estimate the age of fossils by measuring the remaining amounts of these isotopes in the sample.

Coal, petroleum, oil, natural gas.
Two kinds of fossils are body fossils, which preserve the actual remains or impressions of an ancient organism, and trace fossils, which are indirect evidence of an organism's activity, such as footprints or burrows.
There are a variety of types of fossils. These include cast fossils, mold fossils, petrified wood, as well as fossil fuels.
Yes, preserved footprints are examples of fossils.
